OT network segmentation reduces incident impact by 70% in critical infrastructure

OT network segmentation reduces incident impact by 70% in critical infrastructure by isolating operational systems from IT-based threats. The mechanism relies on strict separation of control systems and limiting communication pathways between zones. Case studies from energy and water sectors show significantly reduced operational disruption when segmentation policies are enforced. For practitioners, this means prioritising segmentation as a foundational control to protect safety-critical systems and maintain continuity during cyber events.
