The short version

  • Each has a real cost: Chainguard containers Catalog at 19,000 USD/year expensive for teams under 10 people; 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.
  • They diverge on capability: Chainguard covers Hardened container images, HashiCorp Boundary covers Identity-based access.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Chainguard

  • Containers Catalog at 19,000 USD/year expensive for teams under 10 people
  • Per-image pricing for containers requires custom quotes with no transparency
  • Free tier limited to 5 container images for testing
  • Libraries pricing by ecosystem and developer count lacks transparent per-developer cost
  • VM image catalog pricing opacity makes cost estimation difficult

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.

Answered from the vendors’ own pages

Chainguard: How much is the Chainguard Containers Catalog?

The Containers Catalog is 19,000 USD per year for 10-person engineering teams, providing access to 2,000+ hardened container images.

Source
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.

Chainguard: What SLAs does Chainguard offer?

Chainguard provides contractual CVE remediation SLAs: 7 days for critical vulnerabilities, 14 days for high/medium/low severity, all with priority support.

Source
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.

Chainguard: Can I try Chainguard before purchasing?

Yes. The free tier includes five container images for testing and deployment, allowing hands-on evaluation.

Source
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.

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.
