Open source Firewalls

BunkerWeb

BunkerWeb is a next-generation and open-source Web Application Firewall (WAF). Being a full-featured web server (based on NGINX under the hood), it will protect your web services to make them "secure by default". BunkerWeb integrates seamlessly into your existing environments (Linux, Docker, Swarm, Kubernetes, …) and is fully configurable (don't panic, there is an awesome web UI if you don't like the CLI) to meet your own use-cases . In other words, cybersecurity is no more a hassle. (AGPL)
