OWASP Coraza WAF
OWASP Coraza WAF is a free, open-source Web Application Firewall for APIs and web applications. It supports ModSecurity SecLang rulesets and is fully compatible with the OWASP Core Rule Set. That ruleset covers threats including SQL injection, cross-site scripting, code injection, HTTPoxy, Shellshock and scanner or bot activity. Coraza can run as a sidecar, proxy or library in Go, C++ and WebAssembly. Official connectors are listed for NGINX, Envoy, Caddy, Apache APISIX, proxy-wasm, HAProxy, Traefik and libcoraza. Documentation describes extension points for audit loggers, persistence engines, operators, actions and plugins, with examples for GeoIP and a package containing the Core Rule Set and recommended configuration. The Quick Start requires Go 1.24 or later. Platforms listed are API, Linux, macOS and self-hosted. Coraza offers managed rule sets, API protection and bot management. The v3 internals documentation says persistent collections such as IP, SESSION and RESOURCE are not currently supported. Coraza Playground provides a sandbox web interface for testing rules. The Open source plan is listed at free.
