Overview
Network segmentation splits your OT environment into discrete zones, each governed by tailored firewall rules. This approach stops threats from roaming freely, sharpens monitoring, and boosts performance.
Many OT networks were built in an “air-gap” era—with security by isolation. Today’s connected world and IT/OT convergence have exposed legacy systems to modern ransomware and advanced threats.
Why Deploy OT Network Segmentation?
Segmentation prevents unauthorized access and ransomware spread by isolating Safety Instrumented Systems (SIS), DCS, SCADA and other critical zones. Attackers hitting one segment can’t freely leapfrog into your crown-jewel assets.
We cordon off physical and logical networks—from corporate IT to third-party and plant-to-plant links—creating choke points and security zones that halt malware propagation.
Though live production processes add complexity, our proven tools, methodologies and phased rollout plans ensure you secure zones without unintended downtime.
Key Benefits
- Slows Attackers: Zonal barriers delay lateral movement, buying crucial response time.
- Least Privilege: Restrict user and machine access strictly to needed segments.
- Damage Containment: Isolate breaches to minimize impact on overall operations.
- Data Protection: Shield sensitive repositories behind dedicated security zones.
- Performance Gains: Granular traffic control reduces congestion and latency.
