About
Tenet Security provides a platform for runtime protection of autonomous AI agents, helping enterprises discover, assess, and protect these agents across their environments. The company's patent-pending Agent-side Simulation technology predicts and simulates an agent's likely next actions, intervening to block risky behaviors before they execute. This allows organizations to deploy AI agents at scale by providing visibility, runtime protection, and threat prevention for agent-driven workflows, addressing the challenge of existing security tools lacking visibility into autonomous agent behavior.
