Repello AI is a cybersecurity company focused on securing artificial intelligence systems for enterprise deployments. The company develops products designed to identify vulnerabilities in AI applications and protect AI interactions from adversarial threats. Their product portfolio includes several distinct tools: ARTEMIS, a platform for adversarial red teaming and testing of AI systems; ARGUS, a monitoring and protection product; an AI Asset Inventory tool for cataloging and managing AI assets within an organization; an MCP Gateway for securing model context protocol interactions; and Agent Wiz, targeted at securing AI agent workflows. The company's approach combines proactive adversarial testing with automated, scalable protection mechanisms. Their stated methodology draws on offensive security expertise — finding vulnerabilities before attackers can exploit them — applied specifically to generative AI and large language model (LLM) deployments. Repello AI targets enterprises that are deploying generative AI across business functions and need security coverage tailored to AI-specific threat vectors, such as prompt injection, model abuse, and unsafe AI agent behavior. The company is incorporated in Delaware, USA, and is backed by investors including General Catalyst, Venture Highway, Pi Ventures, and Entrepreneur First. It is also part of the NVIDIA Inception Program and Microsoft for Startups. Advisers include figures from Palo Alto Networks, Meta, and the UK AI Safety Summit.
