An Identity-Aware Proxy (IAP) enforces restricted access by verifying identity before allowing a connection. It goes beyond network-level controls. It ensures every request comes from a known, authorized user, tied to a verified identity. This eliminates blind trust in IP addresses, VPNs, or static credentials.
Identity-Aware Proxy restricted access combines authentication and authorization at the edge. Policies can check user identity, group membership, device status, and context before granting access. This keeps sensitive systems isolated from unverified traffic, even inside private networks.
Traditional access models rely on perimeter security. Once inside the network, users often have unrestricted access. IAP changes the model to verify identity on every request, whether it originates from inside or outside. This supports Zero Trust architecture and addresses lateral movement attacks.
Implementing IAP restricted access requires integration with an identity provider. OAuth 2.0 and OpenID Connect are common standards for that link. Role-based and attribute-based access control policies define who can connect and what they can see.
