Tenet Security
Tenet Security provides runtime protection for autonomous AI agents inside enterprises. Its platform, built around a technique it calls Agent-side Simulation, models an agent's likely next actions before they execute against live systems and can block actions judged risky before they occur, rather than alerting after the fact. It addresses threats specific to agentic AI, including unauthorized access, data exfiltration, agent manipulation and a technique the company calls Agentjacking, where malicious content hidden in emails, documents, logs or databases covertly alters agent behavior. The company was founded by former Cisco AI Defense researchers Barak Sternberg and Nevo Poran and emerged from stealth in 2026 with a six million dollar seed round.

The Picari read
Tenet Security places a runtime sensor inside AI agent environments and uses Agent-Side Simulation to predict an agent's next action and block risky moves before execution. It suits CISOs at enterprises deploying autonomous coding, cloud or customer-facing agents who need runtime visibility beyond EDR, IAM or AI gateways.
