## What it is
A lightweight Web Application Firewall (WAF) implemented with Nginx + Lua (OpenResty). It provides IP black/white lists, URL and User-Agent filtering, CC attack protection, and JSON-format attack logging.

## Use cases
- protect nginx-hosted sites from common web attacks
- block malicious IPs with a blacklist
- rate-limit requests to mitigate CC attacks
- filter suspicious URLs and query parameters
- log blocked requests in JSON for ELK analysis

## When to choose
- you already run Nginx or OpenResty and want simple built-in WAF protection
- you need lightweight, rule-based filtering without a separate appliance
- you want JSON attack logs for centralized analysis

## When to avoid
- you need advanced WAF features like full OWASP CRS coverage or machine-learning detection
- you want a managed or actively developed commercial-grade firewall
- you don't control your Nginx/OpenResty configuration
