  title: Istio Extensions AuthorizationPolicy WorkloadGroup API
  description: The Istio Extensions API (extensions.istio.io) provides configuration resources for extending the Istio service mesh with custom functionality. The WasmPlugin resource enables deploying WebAssembly (Wasm) modules as plugins to the Envoy sidecar proxies, allowing custom processing of network traffic at various phases of the request lifecycle. These resources are defined as Kubernetes Custom Resource Definitions (CRDs) and are accessed via the Kubernetes API server.
