Cairn

General state-space search engine for AI agents, validated on autonomous penetration testing.

Servicefreeglobal

Cairn is a general-purpose AI problem-solving engine that searches an unknown path from a known starting point to a defined goal, with autonomous penetration testing as its first validated use case. Agent workers explore and write confirmed findings to a shared board that other workers build on, with no fixed roles or predefined workflow. It is intended for security researchers and penetration testers operating with explicit authorization on the systems they test.
