Frenos

Frenos is an operational technology (OT) security company that provides a simulated penetration testing platform for industrial and critical infrastructure environments. The platform builds a digital twin of a customer's OT network from existing data such as firewall configurations, asset inventories and known vulnerabilities, then uses an AI reasoning agent to simulate adversary behavior and chain exploits across that model. It can run large numbers of attack path simulations without touching live systems, reducing the risk and downtime of traditional OT penetration testing. The product targets energy, manufacturing, government and healthcare organizations running SCADA, industrial control systems or connected medical devices, and can be deployed on a laptop, on-premises server or in the cloud with data kept on-prem.
