Boundary vs. software-defined perimeter

Software-defined perimeter (SDP) solutions secure access to applications and infrastructure based on user identity.

How Boundary implements SDP principles

Boundary is fundamentally a software-defined perimeter (SDP) solution built on zero trust principles: access to services is granted based on a user's verified identity and intent, not network location or perimeter trust. Boundary is a scalable proxy that enables identity-based access with multiple layers of security controls including dynamic credentials, context-based access, automated host discovery, and access auditing to name a few.
