Ex-Cisco researchers launch Tenet Security to lock down rogue AI agents

Former Cisco artificial intelligence security researchers have launched a new company to tackle a problem that barely existed a year ago: securing the autonomous AI agents enterprises are handing the keys to their most critical systems.

Tenet Security Inc. today formally launched a platform designed to stop malicious AI agent behavior before it reaches production systems. Its core technology, called Agent-Side Simulation, simulates an agent’s likely next moves before they hit live infrastructure.

If a path looks risky, Tenet intervenes before damage occurs and ships a trace explaining why the action was blocked. Most security tools raise an alarm after something suspicious has already happened. Tenet tries to catch the problem first, before the agent actually does anything.

Companies are giving AI agents real power to act on their own. The agents run code, pull from databases and make changes to live systems. The catch is that once an agent is loose in the environment, security teams mostly cannot tell what it’s doing. Tenet says organizations often have as many as five times more AI agents operating than their security teams realize.
