Secure OT Network Architecture for Critical Infrastructure

TAS architected a comprehensive OT cybersecurity framework for a 1,200 MW power plant. The project delivered network segmentation with DMZ, unidirectional security gateways, PAM solutions for privileged access, and continuous monitoring via an industrial SOC. Achieved IEC 62443-3-3 SL2 certification and reduced attack surface by 85% compared to the legacy flat network.
