The short version

  • Only HashiCorp Boundary has a free tier, so it costs nothing to try first.
  • Each has a real cost: HashiCorp Boundary hashiCorp was acquired by IBM in February 2025 and Enterprise licensing now runs through IBM Passport Advantage; IBM has already retired HCP Vault Secrets, so Boundary's roadmap depends on IBM portfolio decisions rather than HashiCorp's own product strategy.; ThetaRay unsupervised models are harder to justify to an examiner than explicit rules, and some regulators still expect documented threshold logic, which can force you to run both systems.
  • They diverge on capability: HashiCorp Boundary covers Identity-based access, ThetaRay covers Unsupervised detection.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

HashiCorp Boundary

  • HashiCorp was acquired by IBM in February 2025 and Enterprise licensing now runs through IBM Passport Advantage; IBM has already retired HCP Vault Secrets, so Boundary's roadmap depends on IBM portfolio decisions rather than HashiCorp's own product strategy.
  • Enterprise pricing is not published anywhere, and the features most organisations actually need for compliance, notably session recording, are Enterprise only, so the free community edition is rarely the version you end up buying.
  • It solves access to infrastructure, not to applications; browser-based internal tools, SaaS admin consoles and APIs need a separate control, so Boundary is one component of a zero-trust programme rather than the whole thing.
  • Running it yourself means operating controllers, worker nodes and a Postgres database in a highly available configuration, and if that control plane is down nobody can reach production, which makes it a new critical dependency.
  • It is materially easier to adopt if you already run Vault and Terraform; teams without that ecosystem face a steeper learning curve than a device-based mesh product like Tailscale, for a similar access outcome.

ThetaRay

  • Unsupervised models are harder to justify to an examiner than explicit rules, and some regulators still expect documented threshold logic, which can force you to run both systems.
  • The alert reduction claim depends heavily on your data, so a parallel run is essential and adds months and cost before you can decommission the incumbent.
  • Coverage is strongest in cross-border and correspondent flows; institutions whose risk is domestic retail fraud will find the fit weaker than a general-purpose monitoring platform.
  • It is a smaller vendor than the incumbents, so integration connectors into legacy core banking systems are often bespoke work rather than a supported adapter.
  • Model retraining and tuning are vendor-led, which means changing detection behaviour is a support conversation rather than something your own analysts can do that afternoon.

Answered from the vendors’ own pages

HashiCorp Boundary: Is Boundary open source?

The community edition is, under MPL 2.0. Boundary Enterprise is commercial and is now sold through IBM Passport Advantage.

ThetaRay: Does it replace a rules engine entirely?

Rarely on day one. Most institutions run it alongside existing rules during a parallel period, and some keep specific regulator-mandated rules permanently.

HashiCorp Boundary: Does it replace a VPN?

For infrastructure access, largely yes. It grants a session to a specific target rather than putting the user on a network, but it does not cover browser-based internal applications.

ThetaRay: Where is the data processed?

SaaS runs on Microsoft Azure with regional deployment options, which is the mechanism for meeting data residency conditions in regulated markets.

HashiCorp Boundary: What does Boundary Enterprise cost?

HashiCorp does not publish Boundary pricing. It is quoted, and since the IBM acquisition it is transacted on IBM licensing paper.

ThetaRay: Is sanctions screening included?

Screening is available on the same platform but licensed as part of the commercial package rather than bundled by default. Confirm it is in your quote.

HashiCorp Boundary: Do I need Vault to use it?

No, but the just-in-time credential brokering that makes Boundary worthwhile depends on Vault or an equivalent secrets store.
