Repello AI

Repello AI is an enterprise platform for autonomous AI red teaming, runtime guardrails, and continuous AI security across LLMs, agents, and MCP. It runs on a proprietary three-phase framework where each phase feeds the next: discovery catalogs all AI systems, models, and integrations to build an AI Bill of Materials and application graph and understand the threat model; automated red teaming (ARTEMIS) attacks that surface; and adaptive guardrails deploy runtime controls calibrated from the red-teaming results, with runtime insights in turn improving future testing. ARTEMIS is the autonomous red teamer: it profiles system capabilities to generate tailored attack strategies, builds threat models, runs parallel attack threads, chains exploits across integrations, and adapts tactics based on agent responses, discovering and validating multi-stage exploit chains in AI agents the way a human red-teamer would and visualizing the attack paths that show exactly where breaches happen. It draws on a proprietary threat-intelligence repository the company describes as 15M+ evolving attack patterns for roughly 15x more coverage than manual testing, offers multi-lingual and multi-modal testing across text, image, and audio, and safeguards against 270+ vulnerability types, with findings mapped to OWASP, NIST, and MITRE and delivered as risk scores, evidence, and compliance-mapped mitigations. Testing is black-box, needing no access to underlying algorithms or code, and integrates into CI/CD to catch AI-specific vulnerabilities before release. Repello also publishes open-source tooling (the Artemis GitHub Action, Whistleblower for system-prompt-leakage and capability discovery, and an awesome-llm-redteaming list) and original research on agentic-browser threats and the collapse of mean-time-to-exploit for AI vulnerabilities. Within the AI-agent-security cluster, Repello is a red-teaming-plus-guardrails entrant closing the discovery-to-runtime loop, comparable to the offensive-testing-for-AI positioning of Mindgard and the runtime posture of the agent-native platforms.
