HashiCorp Boundary

HashiCorp Boundary takes the zero standing privilege philosophy that StrongDM popularised and extends it into HashiCorp's broader infrastructure ecosystem, making it a natural fit for platform engineering teams already running Vault and Terraform. Every session is brokered dynamically with no permanent credentials to compromise, which is a genuinely more complete implementation of least privilege than vaulting-based PAM can achieve for infrastructure access specifically. The open source core tier also means technical teams can start evaluating without a sales conversation.

The honest limitation is scope. Boundary is not a credential vault, and organisations with legacy systems, mainframes, or requirements for visual session recording will need to pair it with a traditional PAM tool or Vault itself. It also has no Gartner Magic Quadrant presence, which matters for procurement processes that require analyst validation.

The verdict: HashiCorp Boundary is right for DevOps and platform engineering teams already invested in the HashiCorp ecosystem wanting the most modern infrastructure access model available. Organisations needing traditional vaulting or compliance-grade session recording should evaluate StrongDM or CyberArk instead.
