As organizations navigate the convergence of informational technology (IT) and operational technology (OT), one truth is becoming clear: what worked for the IT enterprise doesn’t translate to the plant floor. OT environments were not designed with cybersecurity in mind. They rely on legacy systems, proprietary protocols, and flat network architectures, making traditional IT security controls ill-suited, if not outright disruptive for these mission-critical environments.

Nowhere is this misalignment more evident than in traditional network segmentation approaches, where VLANs, firewalls, and NACs lack visibility into industrial devices, rely heavily on infrastructure-centric enforcement, and cannot scale across distributed or fragile systems. As a result, critical operations are left vulnerable.

This whitepaper presents a modern alternative: an integrated approach that merges Claroty xDome’s deep OT asset intelligence with Elisity’s identity-based microsegmentation platform, which enables organizations to implement Zero Trust without risking or disrupting production.
