The short version

  • Only Rust has a free tier, so it costs nothing to try first.
  • Each has a real cost: Rust compile times significantly longer than languages like Go or C; Very Good Security vGS sits in the live path of every request carrying sensitive data, so its latency and availability become yours, and an outage in the proxy is a payment outage no matter how healthy your own systems are.
  • They diverge on capability: Rust covers Memory safety, Very Good Security covers Aliasing proxy.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

Rust

  • Performance-critical applicationsnot Very Good Security
  • Embedded systems and firmwarenot Very Good Security
  • Network services and concurrent applicationsnot Very Good Security

Very Good Security

  • A marketplace facing its first PCI DSS Level 1 assessment that wants to keep card data off its own estate rather than harden a dozen servicesnot Rust
  • A merchant negotiating with a second acquirer that needs card credentials portable so the negotiation is real rather than theoreticalnot Rust
  • A fintech collecting bank account and identity documents that wants sensitive fields absent from logs, backups and analytics warehouses by constructionnot Rust
  • A card issuer that must display a full PAN in its own mobile app without the app or its backend touching cardholder datanot Rust

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Rust

  • Compile times significantly longer than languages like Go or C
  • Smaller ecosystem of libraries and frameworks compared to Python or JavaScript
  • Community still smaller than mainstream languages, reducing available third-party resources

Very Good Security

  • VGS sits in the live path of every request carrying sensitive data, so its latency and availability become yours, and an outage in the proxy is a payment outage no matter how healthy your own systems are.
  • Token portability is the whole selling point yet leaving VGS means migrating tokens back out, a project the vendor has no incentive to streamline, so the lock-in you removed from your acquirer partly moves to VGS.
  • Entry pricing at around one thousand US dollars a month is real money for a pre-revenue fintech, and it buys volume-limited throughput, so cost scales with exactly the growth that made you buy it.
  • Scope reduction is not scope elimination: your QSA still assesses how you integrate, and teams regularly discover that a support tool or an internal admin screen pulled plaintext back in and dragged systems into scope again.
  • Proxy-based interception constrains how you design request flows, and non-standard payloads, streaming uploads or binary formats often need custom routing rules that make debugging production issues noticeably harder.

Answered from the vendors’ own pages

Rust: Is Rust free?

Yes, Rust is free and open-source. The Rust Foundation provides institutional support for this community-driven project, and there are no costs associated with using the programming language.

Source
Very Good Security: Does VGS make me PCI compliant?

No. It removes cardholder data from your systems so your assessment covers a far smaller boundary, but you still complete an assessment and your integration is part of it.

Rust: What license does Rust use?

Rust is open-source and operated under an open-source license. Full license details are available in the policies section of the Rust website.

Source
Very Good Security: Can I move to another processor without re-collecting cards?

Yes, that is a core reason people buy it. The vault reveals stored credentials to whichever processor you route to.

Very Good Security: What does it cost?

Published entry pricing is about one thousand US dollars per month; growth and enterprise tiers are quoted.

Very Good Security: Is it only for card data?

No. The proxy handles any sensitive field, including bank details, national identifiers and documents, though payments is where the product is now focused.
