Zero Trust for Operational Technology extends identity-centric access control to industrial control systems, SCADA networks, and plant-floor assets that were never designed with network authentication in mind, closing the air-gap assumption that attackers have repeatedly exploited. Regulatory pressure from NERC CIP, IEC-62443, and TSA Pipeline Security Directives is accelerating OT Zero Trust adoption across energy, utilities, and manufacturing.
