Which to pick

Pick BunkerWeb when
You self-host web apps on Docker or Kubernetes and want a WAF with sensible security defaults instead of hand-tuning ModSecurity.

Side by side

What it does

A web application firewall built on nginx and ModSecurity that sits in front of your sites as a reverse proxy, with bot protection, DNS blocklists and a web admin panel.

Shares local web services, TCP or UDP services and folders publicly or privately through a zero-trust overlay network, without opening firewall ports.

Watch out

It is AGPL-licensed and some features are in the paid PRO edition.

Self-hosting means running OpenZiti infrastructure, and the free zrok.io service has usage limits.
