BunkerWeb Open Source WAF vs ModSecurity Open Source WAF
Both BunkerWeb Open Source WAF and ModSecurity Open Source WAF are capable WAF solutions. The right choice depends on your specific infrastructure, budget, and feature requirements.
Overview
BunkerWeb and ModSecurity are both open-source WAFs, but they target different users. ModSecurity is the 20-year veteran: a WAF engine that runs as an Apache or Nginx module, powered by the OWASP Core Rule Set. It's the most widely deployed open-source WAF in the world, but configuration is entirely through text files.
BunkerWeb wraps ModSecurity's CRS rules in a modern, Docker-native package with a web UI. You get the same detection engine underneath, but with a visual configuration interface, built-in Let's Encrypt, rate limiting, and bot detection out of the box. It's what ModSecurity would look like if it were built today.
For experienced sysadmins who want maximum control, ModSecurity's raw flexibility is unmatched. For teams that want CRS protection without the configuration overhead, BunkerWeb is the faster path to production.
