Identity-Aware Proxy (IAP) is a security layer that evaluates identity before allowing network access. Unlike traditional firewalls, it works at the application level and uses identity data—user accounts, roles, and policies—to control access. Under ISO 27001, access control is not optional; it is a central clause for meeting compliance. IAP delivers that control without exposing internal services to the public internet.
An ISO 27001-compliant IAP filters traffic against configured policies tied directly to identity providers. It integrates with OAuth, OpenID Connect, SAML, and enterprise directories. Every request is matched to the authenticated user, and every action is scoped to their permissions. Logging is built in, producing verifiable records for ISO 27001 audits. These logs trace who accessed what, when, and from where—ensuring you meet the standard’s requirement for detailed access monitoring.
Deployment is straightforward. Place the Identity-Aware Proxy between the user and the service. Configure the authentication source. Map roles to resources. From that point forward, there is no direct route around it. For ISO 27001, this enables controlled access, minimizes attack surface, and ensures that only authorized identities operate inside the defined system boundaries.
