Score: 6.3/10 (Innovation: 7, Technical: 6, Documentation: 2, Utility: 6)

hCAWN is a zero-regex AI-powered Web Application Firewall (WAF) that uses a hybrid approach combining a quantized LLM (Gated Attention) for anomaly detection and a mathematical 'syntax jitter' measure to detect 0-day attacks without signatures. It runs on under 200MB VRAM via dynamic batching and is being offered as a live challenge to test bypasses, indicating a novel and lightweight security tool.

Target audience: security engineers, devops, backend developers
