The short version

  • 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.; HashiCorp Vault policies are written in HCL with no graphical user interface for policy management or editing
  • They diverge on capability: HashiCorp Boundary covers Just-in-time credentials, HashiCorp Vault covers Secret storage.

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.

HashiCorp Vault

  • Policies are written in HCL with no graphical user interface for policy management or editing
  • Unsealing requires managing multiple key shares and coordinating a quorum of operators
  • Community Edition lacks enterprise features like namespaces and disaster recovery replication
  • Requires additional monitoring solutions for alerting and observability

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.

HashiCorp Vault: Does HashiCorp Vault have a free version?

Yes. The open-source Community Edition is completely free and includes core secrets management, dynamic secrets, and encryption as a service. It is self-hosted with no licensing fees or secret count limits, but lacks enterprise features like namespaces, disaster recovery replication, and Sentinel policies.

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.

HashiCorp Vault: Can I use HashiCorp Vault in production?

The Community Edition is suitable for non-production environments and small teams. For production deployments, organizations typically use HCP Vault Dedicated (managed cloud service starting at approximately 22 USD per month) or Vault Enterprise with custom pricing that includes disaster recovery, performance replication, and 24/7 support.

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 Vault: What are the main integrations available?

Vault integrates with AWS, Azure, Google Cloud, Active Directory, Okta, and 80+ other platforms. It supports dynamic credential generation for cloud providers, database systems, and identity services, enabling centralized secret management across multi-cloud infrastructure.

Source
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.

HashiCorp Vault: Does Vault work offline?

Vault requires network connectivity to function as it is a centralized secrets management server. However, it can be deployed on-premises for air-gapped environments, and clients can cache short-lived tokens for temporary offline access once authenticated.
