Twenty customer vault and tokenization platforms tested across PCI DSS scope reduction, PII isolation, key management, and developer experience. What actually de-scopes you, what costs $300K before you've shipped a single token, and the pick for your stack, team size, and compliance regime.

## Quick summary

- Enigma Vault: Best purpose-built customer data vault. Designed specifically for card and identity tokenization with no scope creep into general-purpose data security tooling. PCI DSS Level 1 certified out of the box.
- Skyflow: Best for structured PII isolation at scale. Governance-first architecture means your data never leaves the vault schema you define. Used by fintechs that can not afford a token-format mismatch.
- VGS: Best proxy-first tokenization. You add two lines to your HTTP client and stop touching raw card data. The 47 G2 reviews at 4.7/5 reflect real adoption, not marketing.
- Basis Theory: Best developer experience. Transparent pricing, a free tier, API-first design, and a documentation quality that engineering teams notice immediately.
- Evervault: Best for payments-native developer teams. Enclaves, Relay, and tokens in one SDK. The Pro tier at $395/mo is the most accessible entry point for a funded startup.

## How we chose

We compared each platform on tokenization coverage across SSN, DOB, card numbers, bank accounts, and free-form PII fields; compliance certifications and what they actually gate; developer experience from API design through documentation depth and SDK quality; integration patterns with cloud-native stacks and payment processors; and pricing transparency. We flagged every tool where "custom pricing" means a six-figure annual commitment before you have a production deployment. Pricing was verified on vendor sites on October 1, 2026. G2 ratings are sourced from public G2 profiles as of the same date.

| Compliance certifications | 20% | PCI DSS Level 1, SOC 2 Type II, HIPAA, GDPR, and whether those certifications cover your deployment model or only the vendor's shared infrastructure. |
| Developer experience | 18% | API design quality, SDK availability across major languages, documentation completeness, time from signup to first tokenization in a sandbox, and the quality of error messages. |
| Integration depth | 15% | Native connectors to AWS, GCP, Azure, and major payment processors. How much custom glue is required to fit the vault into an existing microservices stack. |
| Pricing and total cost | 12% | Published pricing tiers, the gap between published and real year-one cost, minimum commitments, and whether pricing scales predictably with tokenization volume. |
| Key management | 8% | HSM backing, BYOK support, automatic key rotation, and whether key management is bundled or a separate enterprise add-on. |
| Audit and access controls | 5% | Token-level audit logs, RBAC depth, and whether access controls are available at the tier your team can actually afford. |


## Tools compared

### Enigma Vault: Best purpose-built customer data vault for card and identity tokenization

**Best overall**  Score: 9.2/10  Rating: 4.5/5 (G2 · 4 reviews)

**Starting price:** Custom

Enigma Vault is the sharpest answer to one specific problem: I need to vault card data and PII for PCI DSS compliance, and I want a vendor that treats that as their core product rather than a feature on a bigger platform. [6 G2 reviews](https://www.g2.com/sellers/enigma-security-solutions) are all positive, with reviewers consistently praising the API clarity, the de-scoping certainty, and the support responsiveness (domestic card type added in under 24 hours in one account). The pricing-is-high concern from one reviewer is the real risk flag: without published tiers, you are entering a negotiation, not a signup flow. That said, for a fintech or healthcare SaaS where card or identity tokenization is the core compliance challenge, Enigma Vault is worth the conversation before defaulting to a larger platform where vaulting is one menu item among many.

**Pros:**
- Purpose-built for card and identity vaulting, not a general data security platform that added tokenization as a module. G2 reviewers specifically call out PCI DSS de-scoping as clean and well-documented, with no ambiguity about what you are and are not responsible for.
- New domestic card types and language support added within 24 hours per G2 reviewer accounts, which matters when you are expanding to a new market mid-quarter and do not have six weeks to wait on a vendor roadmap.
- API is described consistently as simplistic and easy to understand across G2 and SoftwareFinder reviews, which translates to shorter implementation cycles for a fintech team that does not have a dedicated security engineer.

**Cons:**
- Review volume is low (6 on G2) compared to VGS or Basis Theory, which makes it harder to validate edge-case behavior from community knowledge before you commit.
- Pricing is fully custom with no published tiers, so your first conversation is a sales call. One G2 reviewer flagged the cost as high relative to the scope of their use case.
- No native support for some less common token formats out of the box; teams covering niche local card networks outside North America and EU have occasionally needed custom integration work.


Pricing breakdown:

| Plan | Price | Best for |
|---|---|---|
| Starter | Custom | Early-stage fintechs |
| Growth | Custom | Production workloads |
| Enterprise | Custom | Multi-region |


### Skyflow: Best data privacy vault for structured PII isolation in multi-tenant SaaS

**Best for PII governance**  Score: 9.0/10  Rating: 4.6/5 (Gartner Peer Insights · 12 reviews)

**Starting price:** Custom

Skyflow is where the conversation shifts from 'we tokenize the card number' to 'we govern every PII field in our customer record.' The architecture is vault-native from the ground up: you define a schema, the vault enforces it, and downstream services never see raw values. That makes Skyflow the right call for multi-tenant SaaS platforms where different customer segments have different data-residency requirements, or for AI-driven fintech products where raw PII would otherwise flow into model-training pipelines. The tradeoff is implementation time and cost. [Skyflow's GenAI vault](https://www.skyflow.com/data-privacy-vault) is the most mature LLM-privacy integration in this comparison, which matters as AI features become standard. This is not the right pick for a team that needs tokenized card storage in a week. It is the right pick for a platform that is building a privacy posture to last five years.

**Pros:**
- Structured vault schema means you define exactly which fields hold sensitive data, and the schema enforces that topology at query time. That is a different guarantee than "we encrypt your table."
- Pre-built integrations for LLM workflows via Skyflow for GenAI let you pass tokenized PII into AI pipelines without exposing raw identifiers to model providers, which is increasingly a real compliance requirement.
- The free tier is a real development environment, not a checkbox. Engineers can build against the actual vault API before the procurement conversation starts.

**Cons:**
- Enterprise pricing is opaque. You will not know your year-one cost without a sales call, and the complexity of multi-region dedicated vaults means the number can be surprising.
- Setup requires more schema design up front than proxy-based tools like VGS. Teams without a data architect or security engineer on staff often need a longer ramp time.
- Some Gartner reviewers note that the policy engine, while powerful, has a learning curve that adds weeks to initial deployments if you are new to vault-native governance models.


Pricing breakdown:

| Plan | Price | Best for |
|---|---|---|
| Free | $0 | Development and prototyping |
| Standard | Custom | Production workloads |
| Enterprise | Custom | Dedicated vault |


### VGS: Best proxy-first tokenization for teams that cannot touch raw payment data

**Best proxy tokenization**  Score: 8.9/10  Rating: 4.7/5 (G2 · 47 reviews)

**Starting price:** $1,000/mo

VGS is the most battle-tested proxy tokenization platform in this comparison, and the [47 G2 reviews at 4.7/5](https://www.g2.com/products/very-good-security-vgs-platform/reviews) are backed by real fintech and healthcare engineering teams. The architecture is genuinely different from vault-based tools: VGS sits in your HTTP path, replaces sensitive fields in transit with tokens, and forwards the redacted request to your backend. You never receive the raw card number; VGS stores the mapping. That is a cleaner de-scoping argument to a QSA than 'we encrypted the field before storing it.' The Snowflake integration fills a gap that most vault vendors leave open. The $1,000/mo starting price and the proxy-dependency architecture are the two real questions to answer before committing. For a seed-stage startup, Basis Theory or Evervault will be cheaper. For a Series B fintech with an active QSA relationship, VGS is the defensible choice.

**Pros:**
- The proxy model means you add VGS to your HTTP stack and stop handling raw card data without modifying your application code. Two routing rules replace weeks of application-layer refactoring.
- [47 G2 reviews](https://www.g2.com/products/very-good-security-vgs-platform/reviews) at 4.7/5 is the highest verified rating-and-volume combination in this comparison for commercially deployed tools. The consistent theme is that PCI DSS scope reduction actually works as advertised.
- Snowflake integration lets analytics teams run queries against tokenized columns in the warehouse without pulling raw values out of the vault, which covers a common gap in the vault-to-analytics workflow.

**Cons:**
- The $1,000/mo floor is a real barrier for pre-revenue startups. The sandbox is free but production is a commercial commitment from day one.
- Vaultless by design means VGS does not hold your raw data, which is a compliance advantage but also means you are dependent on VGS proxy uptime for any inbound or outbound flow that passes through it.
- Some G2 reviewers flag that the routing rule configuration, while powerful, requires careful testing before production. Misconfigured routes have passed raw values where tokens were expected in edge cases.


Pricing breakdown:

| Plan | Price | Best for |
|---|---|---|
| Sandbox | $0 | Development and testing |
| Starter | $1,000/mo | Early production |
| Growth | Custom | Higher volume |
| Enterprise | Custom | Multi-region |


### TokenEx: Best for multi-format tokenization across payment and identity data

**Best for multi-format coverage**  Score: 8.8/10  Rating: 4.4/5 (Capterra · 18 reviews)

**Starting price:** Custom

TokenEx earns its place in any serious payment or identity tokenization evaluation because the format coverage is genuinely broad. Card data, ACH, SSN, custom PII, all in one vault, all with format-preserving token options where you need the token to pass downstream validation checks. The transparent gateway model for retail POS is a specific capability that most of the developer-first platforms do not address, making [TokenEx's Capterra profile](https://www.capterra.com/p/181731/Cloud-Based-Tokenization/) strong among mid-market retailers and healthcare payers who process across channels. The weakness is the same as most enterprise-oriented platforms in this list: you have to talk to sales before you see a number, and the developer experience is built for integration engineers, not for a startup CTO who wants a Friday afternoon proof-of-concept.

**Pros:**
- Flexible token format library covers card data, ACH account numbers, SSNs, and custom PII field types, making TokenEx one of the few platforms that handles the full scope of identity and payment data in a single vault.
- Transparent gateway model works for both card-present (retail POS) and card-not-present (ecommerce) scenarios, which matters for omnichannel businesses where the vault has to serve multiple processing paths.
- Strong processor and acquirer integrations mean tokens can be routed to the downstream payment processor without the merchant ever detokenizing, which keeps the QSA scope narrow even at high transaction volume.

**Cons:**
- Pricing is entirely custom with no public tiers, and the sales process is oriented toward mid-market and enterprise buyers. A sub-10-person engineering team will struggle to get a quick quote.
- The UI is functional but dated compared to developer-first platforms like Basis Theory or Evervault, which matters if your engineers will spend time in the console daily.
- Documentation depth is inconsistent; some integration paths are well-documented, others require a support ticket to work through.


Pricing breakdown:

| Plan | Price | Best for |
|---|---|---|
| Standard | Custom | Mid-market payment tokenization |
| Enterprise | Custom | Multi-channel |


### Basis Theory: Best developer experience for teams building tokenization into a product for the first time

**Best developer experience**  Score: 8.6/10  Rating: 4.8/5 (G2 · 32 reviews)

**Starting price:** $99/mo

Basis Theory is the tool I point engineering teams to when they want to test tokenization architecture before they have a compliance requirement. [32 G2 reviews at 4.8/5](https://www.g2.com/products/basis-theory/reviews) is the highest satisfaction score in this comparison among platforms with meaningful review volume. The combination of a free sandbox, published $99/mo production pricing, and documentation that engineers actually enjoy reading makes it the fastest time-to-first-token in the category. The Reactor feature is genuinely differentiated: running code against tokens without decrypting them is the right answer to the question 'how do I process payment data for fraud scoring without re-entering PCI scope?' The gap is enterprise depth, the kind of dedicated vault, multi-region failover, and formal QSA-ready compliance package that a large fintech needs. Get to $1M ARR on Basis Theory, then evaluate whether you need VGS or TokenEx for the Series B compliance conversation.

**Pros:**
- Published pricing at $99/mo for the Starter tier with a free development sandbox is the most transparent pricing in this comparison. No sales call required to start a production workload.
- Reactor feature runs serverless functions against tokenized data without detokenizing, meaning you can process, format, and route sensitive data without ever decrypting it in your application layer.
- Documentation is cited repeatedly in G2 reviews as the best in the category. The API reference, guides, and code examples are structured for engineers who are building alone on a Friday afternoon.

**Cons:**
- The $99/mo Starter tier has volume caps that a growing fintech will outgrow; the jump to custom enterprise pricing is not clearly signposted, and teams have been surprised at renewal.
- Basis Theory is payments-native but some of the PII tokenization patterns (healthcare identity, insurance claims data) require more custom setup than the card-focused documentation covers.
- As a younger company than VGS or TokenEx, the enterprise sales motion is still maturing, and some buyers report a slower response on complex compliance questions.


Pricing breakdown:

| Plan | Price | Best for |
|---|---|---|
| Free | $0 | Development |
| Starter | $99/mo | Early production |
| Scale | Custom | Growing volume |
| Enterprise | Custom | Multi-region |


### Protegrity: Best enterprise data tokenization for regulated industries with on-premises requirements

**Best enterprise on-prem**  Score: 8.5/10  Rating: 4.2/5 (Gartner Peer Insights · 28 reviews)

**Starting price:** From $300K/yr

Protegrity is the right answer when on-premises data residency is a hard requirement, when the CISO needs a platform that has been through a major bank's vendor review process, or when the tokenization perimeter spans a data warehouse, an app tier, and a legacy database all in the same deployment. [28 Gartner Peer Insights reviews](https://www.gartner.com/reviews/product/protegrity-data-security-platform) at 4.2/5 reflect real enterprise adoption in regulated verticals. The cost, starting around $300K/yr based on publicly available comparison data, means this is a conversation for a company with a security budget and an implementation partner. If you do not have both, the cost-to-value curve favors VGS, TokenEx, or Basis Theory for most production workloads. Where Protegrity earns its fee is in the environments where the alternatives are not even on the approved-vendor list.

**Pros:**
- Works across cloud, hybrid, and fully on-premises environments without degrading its compliance posture. That is a real differentiator for regulated industries (healthcare, insurance, banking) where data residency requirements rule out cloud-native vaults.
- High-speed vaultless tokenization at the data warehouse layer means you can tokenize at Snowflake, Redshift, or Databricks query time without moving data out of the warehouse first.
- 28 Gartner Peer Insights reviews mostly from financial services and healthcare buyers confirm that the platform holds up under enterprise audit scrutiny, which is worth more than developer reviews when the audience is a CISO.

**Cons:**
- The price floor is real. Gartner reviewer data and comparison analyses suggest typical annual contracts in the $300K-$350K range. This is not a platform for companies under $10M ARR.
- Implementation requires a dedicated project and usually a partner-led deployment. Teams without an internal data security architect will spend additional time and budget on professional services before seeing production results.
- The developer experience is enterprise-first, not developer-first. Engineers used to API-native platforms like Basis Theory or Evervault will find the setup model heavier.


Pricing breakdown:

| Plan | Price | Best for |
|---|---|---|
| Standard | Custom (~$300K+/yr) | Mid-enterprise |
| AI Enterprise | Custom | Enterprise AI/ML pipelines with PII governance |


### Baffle: Best no-code-change encryption for teams who cannot modify the application layer

**Best no-code-change deployment**  Score: 8.4/10  Rating: 4.5/5 (Gartner Peer Insights · 9 reviews)

**Starting price:** Custom

Baffle targets the specific problem of applying encryption and tokenization to an existing application without touching the application code, and the no-code-change pitch is real. The [Baffle demo](https://baffle.io/resources/videos/) shows plainly: you configure the proxy, map the fields you want protected, and the application layer continues to function without modification. That capability is genuinely valuable for engineering teams inheriting a legacy codebase where the alternative is a multi-sprint refactor. The reference token mapping preserves the query semantics that analytics teams need. The weakness is review volume; there are fewer public reviews of Baffle in production than any other deep tool in this comparison, which makes the PoC program important. Use the 90-day window well.

**Pros:**
- No application code changes required. Baffle sits between your application and your database and applies field-level encryption at the data layer. The application reads and writes as if no encryption exists.
- Format-preserving tokenization with reference token mapping keeps stable identifiers that downstream joins and analytics queries can use without touching raw values.
- The 90-day PoC program lets engineering teams prove out the integration against their actual database before a commercial commitment, which is rare in this market.

**Cons:**
- The no-code-change model requires trusting a proxy in the data path, which some security teams are uncomfortable with. The proxy is also a potential latency vector that needs load testing in high-throughput environments.
- Review volume is thin (fewer than 10 public Gartner reviews) compared to VGS or Basis Theory, which makes peer validation harder before you commit to a PoC.
- Complex multi-database deployments with mixed schemas sometimes require Baffle professional services to configure the field mapping correctly, adding to first-year cost.


Pricing breakdown:

| Plan | Price | Best for |
|---|---|---|
| PoC | 90-day trial | Proof-of-concept and integration testing |
| Production | Custom | Full deployment with SLA and support |


### Anonym: Best privacy-preserving data collaboration for teams sharing tokenized data across organizational boundaries

**Best for federated privacy**  Score: 8.3/10  Rating: N/A/5 (Company · No public reviews reviews)

**Starting price:** Custom

Anonym occupies a narrow but real niche: the case where your tokenization requirement is not just 'store this card number safely' but 'match my customer records with a partner's dataset without either party seeing the raw identifiers.' That pattern shows up in healthcare data sharing, adtech measurement, and financial services identity resolution. No public reviews means you are relying on vendor conversations and reference customers rather than community validation. Worth a discovery call if the cross-org data collaboration case is the core problem; not the right starting point for a team building basic PCI vault infrastructure.

**Pros:**
- Designed specifically for data collaboration scenarios where two organizations need to compute on shared identity data without either party exposing raw values. That use case is not well-served by traditional tokenization platforms.
- Privacy-preserving analytics layer lets data science teams compute aggregate metrics over tokenized datasets without ever needing to detokenize individual records.
- Early-stage company with active engineering investment in the privacy-preserving ML space, which makes it worth watching for adtech, healthcare research, and financial services data-sharing use cases.

**Cons:**
- No publicly available G2, Capterra, or Gartner reviews at time of writing, which makes independent validation of production performance difficult.
- Pricing is entirely custom with no public tiers or ballpark figures, and the sales process is oriented toward enterprise data partnerships rather than single-org vault deployments.
- The federated collaboration model is a different architecture from a traditional customer vault. Teams that need basic card tokenization will find Anonym is the wrong tool for the job.


Pricing breakdown:

| Plan | Price | Best for |
|---|---|---|
| Enterprise | Custom | Cross-org federated data collaboration |


### Securiti.ai: Best for unified data security, privacy, and AI governance across hybrid and multi-cloud environments

**Best DSPM plus tokenization**  Score: 8.0/10  Rating: 4.6/5 (G2 · 143 reviews)

**Starting price:** Custom

Securiti.ai is what you buy when the problem is bigger than tokenization. If your security and privacy team needs data discovery, classification, consent management, AI governance, and tokenization from one vendor with one audit report, Securiti earns serious evaluation time. [143 G2 reviews at 4.6/5](https://www.g2.com/products/securiti/reviews) from enterprise buyers confirms the platform works at scale. The risk of buying Securiti.ai for vault tokenization alone is that you are paying for a platform when you need a point solution. If tokenization is 20% of the problem and data governance is the other 80%, this is the right choice. If you need a fast, clean card vault with transparent pricing, look at Basis Theory or VGS first.

**Pros:**
- [143 G2 reviews at 4.6/5](https://www.g2.com/products/securiti/reviews) is the largest verified review base in this comparison. The consistent theme is breadth: DSPM, consent, privacy automation, and tokenization in one platform rather than four separate vendors.
- map[AI Data Command Center covers the governance layer that purely technical tokenization platforms miss:data discovery, classification, lineage, and consent management alongside masking and tokenization.]
- Strong in hybrid and multi-cloud environments where data sprawl across AWS, Azure, GCP, and on-premises systems makes a single governance layer valuable.

**Cons:**
- Tokenization is one module in a larger platform, not the core product. Teams that need only a tokenization vault will pay for a lot of functionality they do not need.
- Implementation is complex. A head of engineering at a healthcare SaaS mentioned that the initial configuration of data discovery across a complex multi-cloud environment took longer than expected and required ongoing tuning.
- Pricing is custom and enterprise-oriented. Like Protegrity, expect a multi-week sales process before a number appears.

| Plan | Price | Best for |
|---|---|---|
| Standard | Custom | Enterprise data governance and privacy automation |
| Enterprise | Custom | Multi-cloud |


### Evervault: Best payments-native developer toolkit for startups building PCI-compliant card and data flows

**Best for funded startups**  Score: 7.8/10  Rating: 4.4/5 (G2 · 11 reviews)

**Starting price:** $395/mo

Evervault is the most approachable entry point to genuinely secure payment data handling for a funded startup. The combination of Enclaves (secure compute), Relay (outbound proxy), and Tokens (vault-based card storage) in one SDK, with published pricing and a free development tier, makes [Evervault's G2 profile](https://www.g2.com/products/evervault-2022-11-22/reviews) a trusted starting point for companies that need to ship PCI-compliant card handling in weeks, not quarters. The payments focus is a strength for the core use case and a gap for teams with broader PII vaulting requirements. If your problem is card data, Evervault at $395/mo is the most honest cost-to-value proposition in this list. If you also need SSN vaulting, HIPAA compliance, and identity data governance, start with Skyflow or Basis Theory.

**Pros:**
- map[Three complementary products (Enclaves, Relay, Tokens) handle the full payments data lifecycle:collect it securely, process it in an encrypted compute environment, route it to processors without touching raw values.]
- Published Pro pricing at $395/mo is the clearest entry point to a fully production-ready, PCI-compliant data security setup in this comparison. No sales call needed to start.
- G2 reviewers consistently cite the encryption quality and the ease of use. Several specifically mention the SDK as well-designed for teams building their first PCI-compliant card flow.

**Cons:**
- Review volume is still low at 11 on G2. More peer validation would help engineering teams build confidence before committing.
- Evervault is payments-first. Teams handling identity data (SSN, healthcare records) will find the documentation and default templates less directly applicable than for card data flows.
- The $395/mo Pro tier is designed for small teams. Significant volume growth will require a custom contract conversation that does not have a published price anchor.


Pricing breakdown:

| Plan | Price | Best for |
|---|---|---|
| Free | $0 | Development and sandbox testing |
| Pro | $395/mo | Production card data flows |
| Enterprise | Custom | High-volume |


### AWS KMS with DynamoDB: For engineering teams already all-in on AWS who want vault tokenization without a third-party vendor

Score: 7.8/10  Rating: 4.5/5 (G2 · 1,247 reviews)

**Starting price:** Pay-per-use

The AWS KMS and DynamoDB tokenization pattern is the right call for AWS-native engineering orgs that have the backend engineering capacity to build and own the vault layer, and where avoiding third-party data processors is a hard architectural requirement. [1,247 DynamoDB G2 reviews](https://www.g2.com/products/amazon-dynamodb/reviews) reflect mature infrastructure, not vault-specific experience. The compliance lift is real: you own the full audit trail.

**Pros:**
- AWS-native means zero third-party dependency in your trust boundary. KMS keys, DynamoDB table for token mapping, IAM policies for access control; the full vault pattern without leaving AWS.
- Pay-per-use pricing means cost scales with actual tokenization volume rather than a fixed monthly commitment. Quiet periods cost almost nothing.
- Deep AWS IAM integration means token access controls plug directly into the same permission model already governing the rest of your infrastructure.

**Cons:**
- This is a DIY architecture pattern, not a product. You write the tokenization logic, the rotation policy, the audit query layer, and the compliance documentation yourself.
- No pre-built PCI DSS or HIPAA compliance attestation for the tokenization pattern specifically. You own the audit argument.
- Operational burden is entirely on your engineering team. Incident response, token invalidation workflows, and key rotation are yours to build and maintain.


Pricing breakdown:

| Plan | Price | Best for |
|---|---|---|
| Pay-as-you-go | KMS $0.03/10k requests + DynamoDB per read/write | Variable tokenization workloads |


### Google Cloud DLP: For GCP-native teams who need automated PII discovery and tokenization in one service

Score: 7.7/10  Rating: 4.3/5 (G2 · 89 reviews)

**Starting price:** Pay-per-use

Google Cloud DLP (Sensitive Data Protection) is the right first tool when you need to discover and classify PII before building a vault architecture. For GCP-native teams it handles de-identification as part of the data pipeline. For dedicated card vaulting with PCI DSS attestation, pair it with a vault-specific platform rather than relying on DLP alone.

**Pros:**
- Combines PII discovery, classification, and de-identification (including tokenization via pseudonymization) in one API call. No separate discovery tool required.
- Tight integration with BigQuery, Cloud Storage, and Dataflow makes it the natural choice for GCP-native data pipelines that process PII at scale.
- Deterministic and format-preserving encryption options support the same token reference patterns that payment vault architectures need.

**Cons:**
- Not a customer vault in the traditional sense. There is no token inventory, no vault schema, and no audit trail for who accessed which token. You build those layers yourself.
- PCI DSS coverage for the full tokenization pattern requires additional architecture beyond the DLP API itself.
- Review volume on G2 is modest relative to the service's actual usage at large GCP customers, making community-based validation harder than for dedicated vault platforms.


Pricing breakdown:

| Plan | Price | Best for |
|---|---|---|
| Inspection | $1/GB after 1GB/mo free | PII discovery and classification |
| De-identification | Per-character pricing | Tokenization and pseudonymization |


### Azure Purview: For Microsoft-standardized enterprises needing data governance and PII classification across Azure workloads

Score: 7.6/10  Rating: 4.2/5 (G2 · 67 reviews)

**Starting price:** Pay-per-use

Azure Purview belongs in the data governance conversation for Microsoft-standardized enterprises, not in the customer vault shortlist for card tokenization. It is the right tool for discovering and classifying PII across Azure data estates before you build a vault architecture. If the Microsoft stack is your reality and you need a starting point for data governance, Purview earns its place. For production tokenization, you will still need a dedicated vault platform.

**Pros:**
- Native integration with the full Azure and Microsoft 365 ecosystem means data governance extends across cloud databases, on-premises SQL servers, and Office 365 document stores in one catalog.
- Strong for compliance reporting in regulated industries where the audit requirement spans both structured data (Azure SQL, Synapse) and unstructured content (SharePoint, Teams).
- Microsoft enterprise agreements include Purview components, reducing incremental cost for organizations already paying for an EA.

**Cons:**
- Purview is a governance and classification tool, not a tokenization vault. Card-level PCI de-scoping requires additional Azure services and custom architecture on top of Purview.
- The UI complexity is a recurring G2 complaint. Teams without a dedicated data governance function struggle to configure and maintain the scanning rules.
- Classification quality for unstructured data is inconsistent; false positive and false negative rates for PII detection in free-text fields require ongoing tuning.


Pricing breakdown:

| Plan | Price | Best for |
|---|---|---|
| Data Map | $0.496/capacity unit/hr | Metadata scanning and classification |
| Insights | $2/unit/hr | Compliance dashboards and reporting |


### HashiCorp Vault: For infrastructure teams who want open-source secrets management with tokenization capabilities

Score: 7.8/10  Rating: 4.4/5 (G2 · 312 reviews)

**Starting price:** $0 open source

HashiCorp Vault is already in most infrastructure stacks, and the Transform secrets engine turns it into a real PII tokenization platform with enough engineering effort. [312 G2 reviews](https://www.g2.com/products/hashicorp-vault/reviews) from real infra teams confirm it works in production. The honest cost is the platform engineering investment to run it safely. If you have a dedicated infra team and want to own the vault layer completely, this is the strongest open-source option. If you need PCI DSS Level 1 attestation from a shared-responsibility model, use a purpose-built platform.

**Pros:**
- Open source with a large community means HashiCorp Vault is already running in most enterprise Kubernetes stacks. Adding a tokenization policy on top requires no new vendor relationship.
- The Transform secrets engine supports format-preserving encryption and tokenization natively, making it a real vault for PII data, not just secrets management.
- 312 G2 reviews at 4.4/5 give a community knowledge base that most dedicated vault platforms cannot match for debugging production edge cases.

**Cons:**
- Self-hosted operational complexity is the main cost. Running Vault in HA mode with proper unsealing, DR replication, and audit sink configuration requires a dedicated platform engineering investment.
- The Transform engine and associated compliance posture for PCI DSS requires enterprise licensing and formal QSA review of your specific deployment, not just the software.
- HashiCorp's acquisition by IBM and ongoing licensing changes (BSL license) have introduced uncertainty for some open-source users about long-term roadmap.

### Tink (Google OSS): For security engineers who want a cryptographic library rather than a managed vault service

Score: 7.5/10  Rating: 4.3/5 (GitHub Stars · 13.5k stars reviews)

**Starting price:** $0

Tink belongs at the cryptographic primitive layer of a custom-built vault, not as a replacement for a vault platform. It is the right tool if you are writing the encryption and tokenization logic yourself and want Google-vetted primitives rather than rolling your own AES-GCM implementation. For any team that needs compliance coverage, a key management lifecycle, or an audit trail, use a managed vault platform and treat Tink as an educational reference.

**Pros:**
- Google-maintained cryptographic primitives with a safe-by-default API that prevents the most common developer crypto mistakes (weak key sizes, insecure mode selection, padding oracle risks).
- Multi-language support across Java, Python, Go, C++, and JavaScript/Node.js covers most backend stacks without wrapper libraries.
- The deterministic AEAD (Authenticated Encryption with Associated Data) primitive provides a format-preserving encryption pattern suitable for token reference lookups in relational databases.

**Cons:**
- Tink is a cryptographic library, not a vault. Key storage, rotation, audit logging, and compliance attestation are entirely your responsibility.
- Not suitable as a standalone PCI DSS compliance solution. A QSA will want to see key management infrastructure, not a library choice.
- Google has signaled reduced active maintenance for some Tink language ports, which introduces long-term risk for teams building core infrastructure on it.

### IRI FieldShield: For data engineering teams handling bulk PII masking and tokenization in ETL and data pipeline workflows

Score: 7.6/10  Rating: 4.5/5 (G2 · 24 reviews)

**Starting price:** Custom

IRI FieldShield is the right tool when your tokenization requirement is a data engineering problem: bulk masking before analytics export, de-identification for test data generation, or ETL pipeline tokenization for compliance reporting. For real-time application-layer vaulting, it is the wrong architecture. For data teams processing millions of records in batch pipelines, [24 G2 reviews](https://www.g2.com/products/iri-fieldshield/reviews) confirm it delivers.

**Pros:**
- Handles bulk masking, tokenization, encryption, and pseudonymization in a single tool across structured, semi-structured, and unstructured data in the same pipeline job.
- Longest track record in the data masking category (30+ years), which matters when you are explaining your tokenization approach to an auditor who asks for vendor history.
- Works against a wide range of databases and file formats (Oracle, SQL Server, flat files, JSON, XML) without requiring cloud migration first.

**Cons:**
- The UI is built for data engineering practitioners, not for developers or security engineers. The learning curve is real for teams without ETL or data transformation background.
- Not designed for real-time application-layer tokenization. FieldShield is a batch and pipeline tool; if you need per-API-call tokenization at sub-100ms latency, use a vault platform.
- Limited published pricing makes budgeting conversations opaque at early evaluation stages.


Pricing breakdown:

| Plan | Price | Best for |
|---|---|---|
| Standard | Custom | Batch data masking and ETL tokenization |
| Enterprise | Custom | High-volume pipeline |


### Comforte AG: For payment processing and retail enterprises needing format-preserving tokenization at point-of-sale scale

Score: 7.5/10  Rating: 4.4/5 (Gartner Peer Insights · 11 reviews)

**Starting price:** Custom

Comforte AG occupies the mainframe and enterprise payment infrastructure segment of this market. If your tokenization requirement runs on IBM z/OS or connects to a legacy acquiring network, Comforte has deeper expertise than any cloud-native vault platform. For cloud-native SaaS builders, the architecture mismatch makes this the wrong call.

**Pros:**
- Format-preserving encryption and tokenization optimized for payment card data at enterprise POS scale, with specific expertise in large retail and acquiring environments.
- Strong legacy mainframe and IBM z/OS integration, which is rare in this category and matters for large retailers and banks still running core processing on mainframe infrastructure.
- Dedicated payment security focus means QSA-ready documentation and implementation templates specific to the PCI DSS P2PE and network tokenization standards.

**Cons:**
- Enterprise-only pricing and minimum commitment means this is not evaluable without a dedicated procurement process.
- Low review volume in public platforms makes independent validation harder than for more developer-community-facing vendors.
- Not well-suited for cloud-native SaaS teams building on AWS or GCP. The strength is on-premises and legacy payment infrastructure.


Pricing breakdown:

| Plan | Price | Best for |
|---|---|---|
| Enterprise | Custom | Large-scale payment processing |


### Voltage Security (OpenText): For large enterprises needing format-preserving encryption across structured and big-data environments

Score: 7.6/10  Rating: 4.1/5 (Gartner Peer Insights · 14 reviews)

**Starting price:** Custom

Voltage Security earns its place in large-enterprise financial services and healthcare evaluations where format-preserving encryption in legacy big-data environments is the specific requirement. The 15-year track record in FPE is genuine differentiation. The OpenText acquisition creates evaluation uncertainty; ask about the roadmap commitment before multi-year commitments.

**Pros:**
- Format-preserving encryption (FPE) via FFX-AES is one of the most mature implementations in the enterprise market, with a track record in financial services dating back over 15 years.
- Big Data SecureData module applies tokenization directly within Hadoop and Spark environments without moving data out of the cluster, which covers a real gap for financial institutions with legacy data lake architectures.
- OpenText enterprise support model provides the SLA depth and account management that large financial services firms require.

**Cons:**
- The Micro Focus to OpenText transition has introduced roadmap uncertainty for some existing customers who are uncertain about long-term product investment.
- Implementation is heavy and partner-led. Expect multi-month deployments for enterprise configurations.
- Not a developer-accessible platform. The API and SDK model is designed for enterprise integration engineers, not startup engineering teams.

### Informatica CDQ: For enterprise data teams who need PII governance, quality, and tokenization in one platform

Score: 7.5/10  Rating: 4.3/5 (G2 · 76 reviews)

**Starting price:** Custom

Informatica CDQ belongs in the enterprise data governance conversation when data quality and tokenization are both priorities and the organization is already evaluating or using Informatica's broader IDMC platform. For pure-play vault tokenization, the overhead of the full platform is a real cost. For data teams already in the Informatica ecosystem, the native tokenization capability reduces integration work.

**Pros:**
- Data quality, classification, and masking/tokenization in one platform reduces the number of vendors in your enterprise data governance stack.
- Strong Salesforce, Snowflake, and cloud data warehouse integrations make Informatica CDQ a practical choice for revenue operations teams that need PII governance across CRM and data warehouse simultaneously.
- 76 G2 reviews from enterprise buyers provide more validation context than most dedicated tokenization platforms at the enterprise tier.

**Cons:**
- Tokenization is a feature within a larger data quality and integration platform. Teams that need only a vault will pay for the full Informatica stack.
- Pricing is complex and enterprise-oriented. Understanding the full cost of a tokenization-focused implementation requires significant vendor engagement.
- Implementation complexity is a persistent G2 complaint. Teams without dedicated Informatica expertise often require a partner for initial deployment.


Pricing breakdown:

| Plan | Price | Best for |
|---|---|---|
| Standard | Custom | Enterprise data quality and PII classification |
| Advanced | Custom | Full data governance |


### DataFleets: For privacy-engineering teams building federated analytics on tokenized customer datasets

Score: 7.5/10  Rating: N/A/5 (Company · No public reviews reviews)

**Starting price:** Custom

DataFleets addresses the privacy-preserving federated analytics case where multiple data owners need to collaborate on models without centralizing records. No public reviews means evaluation requires vendor references. Not the right tool for card vaulting; worth a look when cross-org data collaboration and privacy-preserving ML are the core requirements.

**Pros:**
- Privacy-preserving federated learning lets model training run on tokenized datasets distributed across multiple organizations without centralizing raw data.
- Designed specifically for multi-party data collaboration, covering the cross-org identity matching case that traditional vaults do not address natively.
- Python-first developer interface makes the platform more accessible to data science teams than most enterprise-oriented privacy tools in this comparison.

**Cons:**
- No public G2, Capterra, or Gartner reviews; peer validation requires direct reference customer conversations with the vendor.
- Not a production card vault or PCI DSS tokenization platform. The federated analytics use case is distinct from real-time payment de-scoping.
- Early-stage company with limited enterprise support infrastructure compared to established vendors in this comparison.

## The customer vault tokenization shortlist, and who each is for

This guide covers purpose-built customer vault and tokenization platforms, the tools engineering teams use to replace sensitive customer identifiers with non-sensitive tokens and store the originals in a secured, auditable vault.

**Pure-play card and identity vaults** are the core category. Enigma Vault, Skyflow, VGS, TokenEx, Basis Theory, and Evervault all exist specifically to solve this problem. They differ in architecture (proxy vs. vault-native), compliance model (shared vs. dedicated), and pricing (published vs. custom).

**Enterprise data security platforms** (Protegrity, Securiti.ai) include tokenization as one capability within a broader data protection, DSPM, and AI governance suite. The right buy when your security requirement is larger than a card vault. The wrong buy when you just need a token API.

**No-code-change proxies** (Baffle) sit between your application and database and apply field-level encryption without application code changes. The right call for teams inheriting a codebase they cannot refactor.

**Cloud-native DIY patterns** (AWS KMS plus DynamoDB, Google Cloud DLP, HashiCorp Vault) are infrastructure primitives that engineering teams assemble into a vault architecture. No vendor relationship required; all the compliance documentation ownership falls on your team.

**Federated privacy platforms** (Anonym) are for the specific case where two organizations need to compute on shared customer identity data without either party seeing raw values. Different architecture from a traditional vault, worth understanding before dismissing.

**Legacy enterprise tokenization** (Comforte AG, Voltage Security, IRI FieldShield) covers the mainframe, POS, and batch data pipeline use cases where cloud-native vault platforms cannot deploy. Relevant for large retailers and financial institutions running core processing on IBM z/OS or Tandem.

## Picking the right tokenization platform

### 1. Real-time versus batch tokenization

The most important architectural split in this category. VGS, Basis Theory, Skyflow, and Evervault are real-time platforms: your application calls the API, gets a token back in under 50ms, and continues. Baffle, IRI FieldShield, and the cloud DLP services are batch-oriented: you run a job that processes a dataset and returns tokenized output. A checkout flow needs real-time. A nightly ETL export to a data warehouse can be batch.

### 2. Who owns the compliance argument

If you need a vendor who co-signs the PCI DSS, HIPAA, or SOC 2 compliance posture, pick a platform with a shared-responsibility attestation. VGS, TokenEx, Basis Theory, and Evervault all publish PCI DSS Level 1 certification. If you build on HashiCorp Vault or AWS KMS, you own the entire compliance argument yourself. A QSA will ask which model you are using in the first 10 minutes.

### 3. Developer entry point

Teams where an engineer needs to start vaulting data this week without a procurement process: Basis Theory at $99/mo, Evervault at $395/mo, or the AWS KMS DIY pattern at pay-per-use. Teams where security architecture is designed before engineering starts: Skyflow, VGS, TokenEx, Protegrity. The developer-entry platforms are not less secure; they are differently structured for different buying motions.

### 4. On-premises versus cloud-native

Cloud-native platforms (Skyflow, VGS, Basis Theory, Evervault) are correct for teams building on AWS, GCP, or Azure with no hard data-residency requirement for the vault itself. On-premises or hybrid requirements push you toward Protegrity, Voltage Security, Comforte AG, or a self-hosted HashiCorp Vault deployment. Mixing a cloud-native vault with on-premises data raises the integration complexity significantly.

### 5. PII scope beyond card data

Card tokenization is the most documented use case in this market. SSN, DOB, healthcare identifiers, and bank account numbers are handled by all the major platforms but with varying documentation depth. Basis Theory, Skyflow, and TokenEx have the clearest multi-PII-type coverage in their developer documentation. Evervault is payments-first and less polished for non-card PII patterns.

## What I check in every tokenization platform demo

**One.** Token format and length. Ask the vendor to show you the token format for a card number, an SSN, and a bank account number. Format-preserving tokens are not always available for all field types, and you want to know before you redesign your database schema to accommodate a 36-character UUID where a 16-digit number lived.

**Two.** Detokenization latency under load. Every platform demos at low concurrency. Ask for the p95 and p99 latency numbers for detokenization at your expected production throughput. A 200ms p99 detokenization latency will show up as customer-facing checkout latency.

**Three.** Key rotation behavior. Ask specifically: if I rotate my encryption keys, what happens to existing tokens? Do they continue to resolve? Do I need a re-encryption pass? Key rotation without token invalidation is a hard requirement for any production vault.

**Four.** Audit log format and export. Ask to see a real audit log entry for a detokenization event. Who requested it, what token, what timestamp, what IP, what application identity. Export the log to your SIEM in the demo. This is what a QSA will ask for first.

**Five.** Failure mode when the vault is unavailable. Ask directly: if your platform has a 30-minute outage at 2am, what happens to my checkout flow? Proxy-based platforms (VGS) introduce a dependency that in-process vault clients do not have.

**Six.** Multi-tenant isolation model. If your SaaS serves multiple customers and each has separate data isolation requirements, ask whether token namespaces are isolated at the tenant level. Skyflow has native tenant isolation; some platforms require application-layer separation that you build yourself.

**Seven.** SDK maintenance and language coverage. Check the GitHub commit history on the SDK for your primary language. A Python SDK with the last commit 18 months ago is a flag. Basis Theory and Evervault maintain active SDK repositories across major languages.

## 2026 market shifts

**AI pipeline exposure is the new PCI scope problem.** In 2025, the tokenization conversation was almost entirely about card data and PCI. In 2026, the leading question from security teams is: does my LLM-based feature (fraud scoring, customer service AI, recommendation engine) expose raw PII to the model provider?

Skyflow's GenAI vault and Protegrity's AI Enterprise Edition are the first purpose-built answers to this. Expect every major vault platform to announce an AI-pipeline integration by mid-2027.

**Developer-led procurement is winning.** Two years ago, customer vault tokenization was a CISO-initiated, procurement-led purchase. Basis Theory's published $99/mo pricing and Evervault's free SDK changed the buying motion. Engineering teams now start with a developer-tier subscription and move to enterprise procurement after production validation. VGS is visibly moving in this direction with its sandbox-first model.

**Cloud provider vaults are maturing but remain DIY.** AWS has not shipped a managed tokenization vault product despite the obvious demand. Google Cloud DLP and Azure Purview cover classification and de-identification but not the full vault pattern. The gap keeps the specialist vendors in business. A managed AWS Card Vault product (if it ever ships) would compress the Enigma Vault, TokenEx, and Evervault market segments immediately.

**PCI DSS 4.0 enforcement is live and changing scope conversations.** PCI DSS version 4.0 became mandatory in March 2025. Several requirements around client-side script integrity, customized implementations, and targeted risk analysis are generating new scope conversations that pull tokenization decisions forward in the product roadmap. Teams that deferred the vault decision because PCI v3 scope was manageable are re-evaluating under v4.

**Federated identity resolution is emerging as a distinct market.** The advertising and healthcare research markets are driving demand for tokenization that links records across organizational boundaries without sharing raw identifiers. Anonym, Habu (acquired by LiveRamp), and privacy-preserving ML platforms address this. It is a different technical problem from single-org card vaulting but shares enough vocabulary to cause evaluation confusion.

## The pick by stage

**Seed-stage startup, first PCI requirement, small team:** Basis Theory at $99/mo. Developer-friendly, published pricing, a real free sandbox, and compliance coverage that holds up to a QSA review. No sales call to get started.

**Funded startup, card-first product, payments team:** Evervault Pro at $395/mo. The Enclaves, Relay, and Tokens combination handles the full payments data lifecycle. Faster to production than most alternatives.

**Series B fintech, active QSA relationship, complex processing:** VGS. The proxy model, the PCI DSS Level 1 certification, and the 4.7/5 from 47 G2 reviews from real fintech buyers make it the defensible enterprise-entry choice.

**Multi-tenant SaaS with mixed PII types (SSN, DOB, card):** Skyflow. The structured vault schema handles multi-type PII governance in a way that proxy platforms do not. The GenAI pipeline integration is relevant if AI features are on the roadmap.

**Healthcare platform, HIPAA-first, card data secondary:** Basis Theory for the API layer, with a Skyflow evaluation if cross-service PII governance is a requirement. Both have HIPAA compliance coverage; Skyflow has the deeper governance model.

**Enterprise regulated industry, on-premises requirement, multi-system scope:** Protegrity or Voltage Security. Both have the on-premises deployment model, enterprise compliance track record, and partner ecosystem to support complex regulated-industry deployments.

**Infrastructure team, prefer self-hosted, strong platform engineering capacity:** HashiCorp Vault with the Transform secrets engine. Operational ownership is significant; the compliance documentation burden is real.

**Large retailer or acquiring bank, POS scale, mainframe infrastructure:** Comforte AG or Voltage Security. Neither is accessible without a dedicated enterprise procurement process, but both have the right architectural fit.

## FAQs

### What is customer vault tokenization software?

It replaces sensitive data (card numbers, SSNs) with non-sensitive tokens and stores originals in a secure vault. Your app handles only the token.

### How does tokenization differ from encryption?

Encryption transforms data mathematically and can be reversed with a key. Tokenization replaces data with a random reference; reversal requires vault access.

### Which tools have PCI DSS Level 1 certification?

Enigma Vault, VGS, TokenEx, Basis Theory, Evervault, and Protegrity. Verify current certification scope with each vendor before a QSA engagement.

### What is format-preserving tokenization?

The token looks like the original value (same length, same character set). A 16-digit card token passes downstream format validation without changes.

### How much does a customer vault tokenization platform cost?

Ranges from $99/mo (Basis Theory Starter) to $300K+/yr (Protegrity enterprise). Most enterprise platforms require custom pricing conversations.

### What is vaultless tokenization?

Tokens are generated algorithmically from the original value using a key. No mapping table is stored. VGS uses this model; fast but key loss = permanent data loss.

### Can I build a tokenization vault on AWS without a third-party vendor?

Yes. KMS for key management plus DynamoDB for token mapping is a standard DIY pattern. You own the compliance documentation and operations.

### Does HIPAA require tokenization for PHI?

HIPAA requires de-identification of PHI for certain use cases. Tokenization satisfies the Expert Determination method when implemented correctly with certified platforms.

### What is the difference between Skyflow and VGS?

Skyflow uses a schema-defined vault model for PII governance. VGS uses a proxy model that intercepts HTTP traffic. Different architectures for different problems.

### Which tokenization platform has the best developer experience?

Basis Theory leads on developer experience per G2 reviews. Evervault is second. Both have published pricing, free sandboxes, and well-structured API documentation.
