open-policy-agent/opa-envoy-plugin — A plugin to enforce OPA policies with Envoy

Description and use

The **OPA Envoy Plugin** is an open‑source extension that integrates the Open Policy Agent (OPA) with Envoy proxy, allowing real‑time enforcement of fine‑grained security and compliance policies on inbound and outbound traffic. By offloading policy evaluation to OPA, the plugin enables dynamic, context‑aware decisions for authentication, authorization, and other security controls without modifying application code. It is particularly useful for cloud‑native environments where consistent, programmable policy enforcement across microservices is required.

Problem
