Our hardened Roundcube Docker image runs as nobody, can chown nothing, and treats every request as hostile. Here is the full unprivileged + WAF security model — and why default webmail containers are a liability.

Default Docker is barely a container at all — root, mutable, all caps, shared kernel. This is the ten-flag hardening checklist that turns it into something a real attacker has to work to break: rootless, read-only, cap-drop, no-new-privileges, distroless, secrets, segmentation, scanning. With a worked NGINX + PHP-FPM compose example.

The complete WordPress + NGINX + PHP-FPM setup for Debian and Ubuntu: server block config, pool tuning, FastCGI caching for anonymous traffic, Redis object cache, Brotli compression, and security hardening with ModSecurity and Snuffleupagus.

A friendly, jargon-free walkthrough: install Snuffleupagus from the myguard APT repo, pick the right rulebook for your stack (WordPress, Roundcube, generic PHP, internal agent), wire it into a PHP-FPM pool, and avoid the 5 traps that bite everyone the first time.
