About Tenet Security
Tenet Security builds a runtime security platform for AI agents, providing real-time visibility and defense for autonomous agents that hold elevated privileges inside enterprises. Its Agent-Side Simulation engine intercepts agent tool calls and execution paths to stop hijacked or rogue behavior before it reaches infrastructure, a layer existing tools like EDR, WAF and IAM cannot observe. Founded in 2025 by security researchers with offensive backgrounds from Unit 8200 and Cisco AI Defense, the company is known for its Agentjacking research on hijacking AI coding agents.
