UUSEC WAF

UUSEC WAF is a self‑hostable, open‑source web application firewall and API security gateway built as a fork of nginx. It provides industrial‑grade protection across three layers – traffic, system, and runtime – and incorporates AI‑driven anomaly detection to distinguish normal from malicious HTTP traffic without requiring manual rule updates for new vulnerabilities.

The product includes a cache‑cleaning feature that supports regular‑expression URL matching, offering more flexible CDN acceleration than the commercial nginx proxy_cache_purge. It also integrates host‑level intrusion prevention and runtime application self‑protection (HIPS and RASP) to block low‑level system attacks and zero‑day exploits in Java and PHP environments.

Security administrators can define rules through a traditional UI or write Lua scripts for advanced, programmable protection. Built‑in semantic analysis engines target SQL injection, XSS, remote code execution, and local file inclusion, decoding complex payloads such as base64 and JSON to achieve high detection accuracy with low false‑positive rates.
