HashiCorp Boundary vs HashiCorp Vault
HashiCorp Boundary
HashiCorp Boundary is an identity-aware session broker for remote access to infrastructure. It pairs naturally with HashiCorp Vault to provide just-in-time credential brokering: users authenticate with Boundary using their identity provider, Boundary requests short-lived credentials from Vault, and injects them into the session without exposing them. Boundary is open source (MPL 2.0) with a commercial HCP Boundary cloud offering.
Pros
- Natural fit for teams already running HashiCorp Vault
- Open source core with no license cost
- Terraform-native workflow for declarative access policies
- HCP option removes operational overhead
Cons
- Younger product; smaller community than Teleport
- Session recording requires Enterprise tier
- Best value comes bundled with Vault — less compelling standalone
- Fewer enterprise integrations than legacy PAM
Pricing: Free (OSS); HCP Boundary from $0.024/session/hr
