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.

Microsoft Defender for Endpoint

  • Pricing not published on public websites; quote required from Microsoft sales
  • Defender for Endpoint Plan 1 and Plan 2 do not include server licenses; additional licensing required for server protection
  • Specific feature differences between Plan 1 and Plan 2 require consulting Microsoft documentation
