Tenet Security ✓

Tenet Security is the agent behavior security platform. It protects AI agents while they act, governing what an agent does after it is authenticated and operating under its authorized intent. This is the behavioral layer that identity, posture, and prompt guardrails cannot see, and it is where the dangerous agentic attacks happen.

A single lightweight sensor runs inside the agent's own process, on the endpoint or in the cloud, with no gateways, proxies, or code changes. It correlates OS activity, network and API calls, and the model's reasoning into one live session timeline. When an action looks dangerous, Agent-Side Simulation (patent pending) predicts the agent's next moves and blocks the harmful step before it executes, backed by a real-time block and a live kill switch that actually stops the agent, not an alert after the fact. The sensor deploys in a few minutes, and a full agent risk assessment takes three hours or less.

Tenet covers coding agents and production cloud agents, protecting tens of millions of end-users across enterprise environments. The founding team built Cisco's AI Defense and leads original agent-security research, including the discovery of the agentjacking and ghostjacking attack classes. That research has been featured in The Hacker News, Dark Reading, and VentureBeat, and the ghostjacking agentic kill chain was presented at DEFCON.
