Think of AI agents as new employees who can access your company’s most sensitive systems, execute code, and make decisions autonomously. Now imagine those employees have no background checks, no supervision, and no off switch. That’s roughly the security problem Tenet Security wants to solve.
The cybersecurity startup emerged from stealth on June 17 with $6 million in seed funding led by The Westly Group and MizMaa Ventures. Its pitch: detect and neutralize dangerous AI agentic behavior in real time, before autonomous systems can exfiltrate data, hijack other agents, or simply go off-script in ways that cause real damage.
What Tenet actually does
At the core of Tenet’s platform is something the company calls Agent-Side Simulation, a patent-pending technology designed to predict harmful actions before they happen. Instead of waiting for an AI agent to do something catastrophic and then cleaning up the mess, Tenet’s system simulates what the agent is about to do and blocks it if the outcome looks dangerous.
The approach works across cloud and endpoint environments. Tenet claims it deploys in hours or even minutes, with no code changes required on the customer’s side. The company says its platform can scale from monitoring two agents to more than 20, and that it has already blocked real attacks in production environments. Tenet reports that its deployments currently protect systems serving over 24 million users.
