Summary

BunkerWeb is an open-source web application firewall and NGINX-based web server that sits in front of web services as a reverse proxy. Its protections include HTTPS with automated Let's Encrypt, HTTP security headers, TLS hardening, ModSecurity with the OWASP Core Rule Set, and automatic bans for suspicious behavior. It can challenge bots using cookies, JavaScript, CAPTCHA, hCaptcha, reCAPTCHA, or Turnstile, and block known malicious IPs through external blacklists and DNS-based blackhole lists. Supported deployment integrations include Docker, Docker autoconf, Swarm, Kubernetes, and Linux. An optional web UI manages instances and configurations, currently with Docker and Linux integrations. The open-source plan is free under the AGPLv3 license. PRO pricing is based on the number of protected services; its Standard option has no technical support, while Enterprise includes dedicated technical support. Kubernetes Gateway API mode is beta. The API documentation recommends limiting access with an IP whitelist and optionally an API token.
