Tenet Security Emerges From Stealth With $6M Seed to Stop Rogue AI Agents Before They Execute

Tenet Security emerged from stealth on June 17 with $6 million in seed funding led by The Westly Group to prevent autonomous AI agents from taking dangerous or costly actions in enterprise environments. Founded by Unit 8200 alumni who previously built Cisco's AI Defense research team, Tenet's patent-pending Agent-side Simulation technology predicts an agent's likely next actions before execution and blocks malicious or wasteful paths in real time. One Fortune 1000 early customer used the platform to catch a runaway agent consuming tens of thousands of dollars in unnecessary tokens over a weekend. The startup addresses threats including agentjacking, prompt injection, unauthorized data exfiltration, and agent-to-agent manipulation.
