Simple and Non-Disruptive Zero Trust Segmentation for OT

Traditional approaches for securing OT (operational technology) devices on OT and ICS networks have long been dependent on maintaining the separation of industrial applications from IT networks and remote-access users.

However, as OT organizations modernize their infrastructure with new technologies, such as Cloud SCADA, DCS and advanced Manufacturing Execution Systems (MES), traditional zoning strategies are no longer sufficient to keep OT environments safe.

Challenges in OT environments include:

• Risk of lateral movement of malware and malicious actors, interzone threats crossing over from IT, and remote users impacting cyber-physical and OT infrastructure
• Detection and mitigation of malware spread and inter-zone threats that affect cyber-physical and OT infrastructure
• Multivendor operational complexity and inconsistency in segmentation controls across extended OT environments
