Tenet Security Emerges From Stealth With $6 Million Seed Funding

Tenet Security has emerged from stealth mode with six million dollars in seed funding to address a critical gap in AI security: detecting and stopping dangerous behavior from AI agents in real time. Founded by former Cisco AI Defense researchers, the company uses its own AI agents to monitor and predict potentially harmful actions before they occur, whether from runaway automation or "agentjacking" attacks where adversaries manipulate agents to act within their authorized permissions. The platform has already proven valuable in early deployments, including blocking attacks at a billion-dollar legal enterprise and catching a runaway agent that racked up tens of thousands of dollars in unnecessary costs over a single weekend.
