Fabraix

Adversarial AI agents that continuously red-team your customer-facing AI to find security vulnerabilities before attackers do.

Fabraix is a web-based adversarial verification platform built for engineering and security teams deploying AI agents in production environments. Powered by Nyx, its autonomous red-teaming engine, Fabraix continuously probes customer-facing AI systems across security, logic, and alignment dimensions using pure blackbox testing that requires no special access or integration. Nyx executes multi-turn, adaptive attack campaigns spanning jailbreaks, prompt injections, data exfiltration, reasoning failures, and alignment drift across text, voice, and image modalities.
