Fabraix

Our agents hack your AI before attackers do

Pure blackbox testing

Point Nyx at any AI system with no integration or internal access — test agents exactly how real users interact with them.

Multi-turn adaptive attacks

Nyx reasons across turns and adapts to your agent's logic, drawing on 10,000+ offensive strategies in long-context campaigns instead of canned prompts.

Multi-modal interaction surfaces

Test across voice, text and images, with websites deployed on the fly for browser agents and custom files for document-processing agents.

Massively parallel coverage

Run thousands of concurrent simulations; coverage scales with compute rather than headcount, with first exploits often found in under an hour.
