Overview

BunkerWeb is a next-generation, open-source Web Application Firewall (WAF).

As a full-featured web server (based on NGINX under the hood), it protects your web services to make them "secure by default." BunkerWeb integrates seamlessly into your existing environments (Linux, Docker, Swarm, Kubernetes, …) as a reverse proxy and is fully configurable (don't panic, there is an awesome web UI if you don't like the CLI) to meet your specific use cases. In other words, cybersecurity is no longer a hassle.

BunkerWeb includes primary security features as part of the core but can be easily extended with additional ones thanks to a plugin system.
