sWAF
A simple Web Application Firewall docker image
...It runs NGINX as a dedicated reverse proxy embedding powerful WAF engines: ModSecurity 3, using OWASP® ModSecurity Core Rule Set (CRS) rules, and NAXSI. It uses acme.sh for Let's Encrypt and other free CA support. A lot of people are self-hosting their own cloud infrastructure (using Nextcloud, Synology, QNAP, a cloud lease server or home-made solutions...), but we can never be too much paranoid about web security for a lot of good reasons. Too much time security is left on the background, or only by using some basic - but not sufficient - options and applications are front-faced to the big bad Internet.
