Overview

What is Fabraix?

Fabraix builds frontier red-teaming AI agents that continuously find security vulnerabilities in customer-facing AI systems. Its flagship agent, Nyx, performs autonomous blackbox adversarial testing across multi-turn interactions, voice, text, and images, surfacing failure modes like prompt injection, hallucination, and logic gaps that static benchmarks miss.
