## What it is
UUSEC WAF is a free, high-performance web application firewall and API security gateway (WAAP) that combines AI/semantic detection engines with traditional rule-based protection. It provides three-layer defense across traffic, system (HIPS), and application runtime (RASP) layers, with features like machine-learning-based 0-day defense and CDN cache purging.

## Use cases
- protect websites from sql injection and xss attacks
- block zero-day exploits without updating rules
- secure and rate-limit apis behind a gateway
- self-host a web application firewall in front of nginx services
- prevent ddos and bot traffic
- automatically provision https certificates with letsencrypt
- add runtime application self-protection to block server-side attacks

## When to choose
- you need a free self-hosted WAF with AI and semantic detection
- you want layered defense including HIPS and RASP beyond traffic filtering
- you run nginx-based sites and want integrated CDN cache purging and API protection

## When to avoid
- you need a managed cloud WAF with vendor support and SLAs
- your stack is Windows-only since it targets Linux deployments
- you only need simple rate limiting without full WAF complexity
