# 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](/boundary/tutorials/hcp-administration/hcp-ssh-cred-injection), [context-based access](/boundary/tutorials/access-management/oidc-idp-groups), [automated host discovery](/boundary/docs/concepts/host-discovery), and [access auditing](/hcp/docs/boundary/audit-logging) to name a few. |
