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.
The world's frontier hacker for AI agents.
- Security auditing of customer-facing AI agents (support bots, code agents, browser agents)
- Continuous adversarial testing in CI/CD pipelines for AI deployments
- Probing for prompt injection, hallucination, policy drift, and logic gaps in multi-turn flows
- Stress-testing AI systems in regulated industries like healthcare, finance, and legal
- Evaluating agent-to-agent coordination and orchestration vulnerabilities
- Point Nyx at any AI system via its blackbox interface—no integration or source code needed
- Select the appropriate blueprint for your domain (support bot, code agent, RL system, browser agent, etc.)
- Run massively parallel attack campaigns across multi-turn interactions, voice, text, and images
- Review surfaced failure modes including jailbreaks, injections, exfiltration, reasoning gaps, and alignment issues
- Integrate Nyx into your CI/CD pipeline to automatically re-test every agent update before shipping
