Envoy Proxy

Envoy Proxy External Authorization API

The Envoy External Authorization API provides a gRPC or HTTP interface for delegating authorization decisions to an external service. When a request arrives, Envoy calls the ext_authz service, which can approve, deny, or modify the request before it is forwarded to the upstream. This enables policy-based access control enforced at the proxy layer.
