Boundary vs. software-defined perimeter

Software-defined perimeter (SDP) solutions secure access to applications and infrastructure based on user identity. Boundary is fundamentally an SDP solution that takes a zero trust approach to security design for system access; access to services is granted based on the scoped identity and intent of a user. 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.
