Ransomware in manufacturing OT is a business continuity event, not just a data breach. A custom containment workflow automates the detection of anomalous file encryption on PLCs, HMIs, and SCADA historians, then triggers isolation before lateral movement halts production. The operational upside is measured in avoided downtime—minutes saved in containment translate directly to millions in preserved throughput and prevented asset damage. This requires integrating OT-specific security monitors (e.g., Nozomi, Claroty) with network segmentation controls and plant floor safety systems to execute a response that is both rapid and failsafe.
