About HashiCorp Boundary

Boundary is an identity-aware proxy that provides a simple, secure way to access hosts and critical systems on your network.
With Boundary you can:
- Integrate with your IdP of choice using OpenID Connect, enabling users to securely sign-in to their Boundary environment
- Provide just-in-time network access to network resources, wherever they reside
- Manage session credentials via a native static credential store, or dynamically generate unique per-session credentials by integrating with HashiCorp Vault
- Automate discovery of new endpoints
- Manage privileged sessions using Boundary’s session controls
- Standardize your team's access workflow with a consistent experience for any type of infrastructure across any provider
Boundary is designed to be straightforward to understand, highly scalable, and resilient. It can run in clouds, on-prem, secure enclaves and more, and does not require an agent to be installed on every end host, making it suitable for access to managed/cloud services and container-based workflows in addition to traditional host systems and services.
