Feature comparison by criteria

What EnigmaVault and Skyflow actually cost

This comparison starts and nearly ends on pricing transparency, because the two companies take opposite approaches.

EnigmaVault publishes its pricing in full. The Lite tier is free, with no credit card required, built for development and initial testing against real PII. Plus runs $49.99/month for production use. Premium runs $249.99/month for high-volume, multi-tenant deployments. You can model your annual cost today, before writing a line of integration code.

Skyflow publishes nothing. Every tier, including the “evaluation available” entry point, requires a sales conversation. There is no free tier, no self-serve signup, and no public number to put in a budget spreadsheet. If you’re trying to get LLM PII tokenization into a product roadmap, that opacity is itself a cost: you can’t scope the project financially until after a sales call.

The practical takeaway: if your team needs to prototype a PII tokenization layer this week, EnigmaVault’s free Lite tier lets you start immediately. Skyflow requires you to request access and wait.

Where the tokenization models actually differ

EnigmaVault does field-level, vault-backed reversible tokenization. A value goes in, a stable token comes out, and the same input always maps to the same token, deterministic by design. That token transits to the LLM; the real value stays in the vault until your application de-tokenizes the response.

Skyflow’s differentiator is polymorphic encryption: a single stored value can be revealed in different forms depending on who, or what system, is asking. A customer service rep might see a masked card number, a billing system might see the full value, and an analytics pipeline might see a format-preserving token that is neither. This is a genuinely more sophisticated access-control model than EnigmaVault’s straightforward tokenize/de-tokenize pattern.

Whether that sophistication matters to you depends entirely on your architecture. If you have one application tier that needs the real value back after an LLM call, EnigmaVault’s model is simpler and does the job. If you have multiple internal consumers of the same underlying data who each need a different view, billing sees one thing, support sees another, analytics sees a third, Skyflow’s polymorphic model removes the need to build that access-control logic yourself.

Feature-by-feature comparison

Two rows do most of the deciding for you. If “built-in entity detection” and “polymorphic token views” aren’t requirements, EnigmaVault matches Skyflow everywhere else and adds a free tier, PCI DSS Level 1, and AWS Marketplace availability on top. If you need either of those two capabilities specifically, Skyflow is the only one of the two that offers them.

Where EnigmaVault wins

Transparent, accessible pricing. Free to start, $49.99/mo to go to production. No sales call required to understand your cost structure. If you’re evaluating a tokenization vendor, this alone removes the biggest friction point in the buying process.

Certification breadth in one vault. PCI DSS Level 1, SOC 2 Type II, and ISO 27001 are included, and the vault handles cards, documents, e-signatures, and general PII under one policy, not just LLM-adjacent data. If your product touches payment data anywhere alongside PII, EnigmaVault’s broader scope means one vendor relationship instead of two.

A real, if small, review base. 6 G2 reviews isn’t a lot by enterprise SaaS standards, but it’s three times Skyflow’s sample size, and the documented pros and cons (collection flow quality, certification depth, thin review count as a real limitation) read as an honest account rather than marketing copy.

Faster time to first integration. Free tier, public API docs, no evaluation-request gate. You can be tokenizing test data against the Data Vault API today.

Where Skyflow wins

Polymorphic encryption for multi-consumer data. If your architecture genuinely needs the same underlying value to resolve differently for different callers, full value for one system, masked for another, Skyflow’s vault handles that natively. Building the equivalent access-control logic on top of a simpler vault is real engineering work Skyflow removes for you.

Purpose-built LLM PII Gateway. Skyflow’s gateway detects 50+ data types and is specifically architected to sit in front of an LLM API call, auto-masking per policy before the prompt is sent. EnigmaVault’s Data Vault API requires you to call tokenization explicitly in your application code rather than sitting as a transparent proxy.

Enterprise-oriented positioning. Skyflow’s custom-quote-only model and evaluation-gated access signal a product built for larger enterprise procurement processes, which may fit your organization if you prefer a guided sales engagement over a self-serve signup.

Where EnigmaVault and Skyflow are a wash

• Reversible, vault-backed tokenization. Both store the real value and hand back a token; neither is a redaction-only tool.
• HIPAA alignment. Both offer HIPAA-aligned deployments, with BAAs available on request.
• API-first architecture. Both integrate via REST API into your existing application or LLM pipeline rather than requiring new infrastructure.
• No FedRAMP. Neither currently carries FedRAMP authorization, so neither is a fit if you need a federal government deployment out of the box.

What reviewers report

EnigmaVault holds a 4.4/5 across 6 G2 reviews. The documented praise centers on its branded intake flow and certification depth for the price; the clearest documented weakness is review volume itself. 6 reviews is thin relative to platforms like Stripe or TokenEx that have thousands.

Skyflow holds a 5.0/5 across exactly 2 G2 reviews. At that sample size, the rating isn’t statistically meaningful; a single additional review in either direction would swing the average substantially. I’d treat a 2-review 5.0 as “no independent signal yet” rather than as evidence of superior satisfaction.

Security and compliance side by side

EnigmaVault’s PCI DSS Level 1 certification is the clearer differentiator here if your tokenization need spans payment data as well as general PII. Skyflow’s certification set is strong but doesn’t lead with payment-specific compliance the way EnigmaVault’s does.

Switching cost and what you keep if you leave

Neither vendor ships a one-click migration tool from the other, which is standard for tokenization vaults: the token mappings themselves are the lock-in, not just the integration code. Moving from either platform means re-tokenizing your live data against the new vault and updating every application call site that references a token.

EnigmaVault’s lower starting cost and free tier make the “try before you build deep integration” path cheaper if you want to validate fit before committing. Skyflow’s sales-gated access means you’re committing earlier in your evaluation process, before you’ve necessarily proven the integration works for your use case.

Who should pick which

Which one I would actually deploy

If you’re building a PII tokenization layer in front of an LLM, I’d point you to EnigmaVault as the better default for most of you. You can start free today, the paid tiers are affordable and transparent, and the certification stack, PCI DSS Level 1, SOC 2 Type II, ISO 27001, covers more ground than most teams need from a single vault. The 6-review G2 base is thin, but it’s real, documented, and three times deeper than the alternative.

Skyflow’s polymorphic encryption is a genuinely interesting piece of engineering, and if your architecture specifically needs one token to resolve differently for different internal consumers, it’s worth your evaluation. But that’s a narrow requirement, and you’d be committing to a custom-quoted, sales-gated product with only 2 public reviews to validate your decision against.

Unless polymorphic role-based token reveal is a named requirement in your architecture, I’d start with EnigmaVault. You can be tokenizing real PII against the free tier before Skyflow’s sales team has returned your evaluation request.

Both sit alongside eight other platforms in my best PII tokenization software for LLM roundup, where Microsoft Presidio and Nightfall AI cover the detection-only end of the spectrum these two vault-backed tools go beyond.
