Block Web Attacks Live: Open-Source WAF with Automatic HTTPS
Putting a Web Application Firewall in front of your app usually means wrestling
certificates, cryptic rules, and a per-request cloud bill. In this video I deploy
a fully self-hosted, open-source WAF in about 10 minutes — automatic TLS, the
OWASP Core Rule Set built in, and a real management UI — then block live attacks
and tune a false positive without opening a hole.
Built on Caddy + Coraza (a ModSecurity-compatible engine) + OWASP CRS v4, with a
FastAPI + React control panel. Runs from prebuilt Docker images. No vendor lock-in,
no per-request fees.

✅ What you'll learn
• Deploy a self-hosted WAF from prebuilt images in minutes
• Get automatic, auto-renewing HTTPS with zero certbot/PEM wrangling
• Block SQL injection, XSS, path traversal, RCE and more with OWASP CRS v4
• See exactly what's blocked and why — rule ID, category, client IP, country
• Tune false positives with a scoped exclusion (no disabling rules, no config files)
• Roll out safely with detection-only mode before switching to blocking
