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.
The world's frontier hacker for AI agents.
Core Features
Pure blackbox testing: no special access, source code, or model weights required
Multi-turn adaptive stress tests that reason across interactions and adapt to agent logic
Multi-modal testing: voice, text, and images, including deploying test websites and custom files
Massively parallel simulations running thousands of concurrent attack campaigns
Self-learning loop: every attack feeds back to sharpen the red team over time
CI/CD integration: re-tests every agent update, prompt change, and tool integration before shipping
Popular Use Cases
- 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
