SECURE WITH CONFIDENCE

Guardrails That Sit Between AI and the Real World

Repello intercepts threats where they actually happen — between your AI model’s decisions and the outside world. Whether it’s user prompts, agent actions, or API interactions, our guardrails operate in real time, powered by world’s largest AI-specific threat intelligence by Repello AI.

RED TEAMED. REAL-TIME.

Born Offensive. Built Defensive.

Repello’s AI Guardrails are informed by battle-tested adversarial insights from the world’s most advanced AI red teaming engine. The same system used to discover critical vulnerabilities in enterprise AI now powers real-time protection.

No handoff. No lag. Just seamless transition from discovery to defense.
