S4x26 Case Study

At the S4x26 POC Pavilion, Frenos completed 154,000 OT attack path simulations in 17 minutes and 7 seconds in a documented engagement. From three assumed-breach starting points (iDMZ, Plant Operations, Enterprise), the platform validated 18 attack paths into the critical Rockwell and Siemens zone. Those paths are exploitable given the actual controls, firewall rules, routing, and configurations modeled in the digital twin.
