Score: 3.8/10 (Innovation: 4, Technical: 4, Documentation: 4, Utility: 3)

Prolog-WAF (Aethel-Core) is a SWI-Prolog based reverse proxy WAF that performs multi-layer URL/HTML/hex decoding and matches incoming traffic against n-gram tokenized threat signatures with sliding-window DDoS detection. The idea of using a logic language for a WAF perimeter is unusual, but the deployment model is unfinished, much of the 'enterprise' knowledge base is proprietary, and the readme leans heavily on unverifiable benchmark claims rather than reproducible examples.

Target audience: security engineers, backend developers
