Policy Enforcement Point
A Policy Enforcement Point, or PEP, is the component that intercepts access attempts and enforces the decision returned by the authorization engine.

Definition
A Policy Enforcement Point is the control point located in an application, API, gateway, proxy, service, or integration layer that captures an access request, sends the relevant context to a Policy Decision Point, and then enforces the returned decision in the protected system. It is where policy becomes action.
Why it matters
The PEP is the gateway to protected resources; if it is bypassed or misconfigured, the entire authorization architecture is compromised.
The Ariovis perspective
Authorization policies should be separated from application code when consistency, auditability or scale require it. Enforcement remains close to the resource while the decision is governed independently.
