Envoy is a cloud-native proxy with many networking features but does not come with built-in features for Web Application Firewall (WAF). Luckily, Envoy provides a plugin interface via WebAssembly - it is possible to customize request handling by implementing a plugin in one of several languages that can compile to WebAssembly. This presentation will show how we brought WAF to Envoy by compiling the off-the-shelf WAF library, Coraza, to WebAssembly.
