What is OT network segmentation?
OT network segmentation separates industrial networks into zones by function and risk, and controls traffic between them. It often follows the Purdue model and IEC 62443 zones and conduits, so an attack on office IT cannot easily reach controllers. A review checks the design, firewall rules and real traffic paths.

Flat networks let attacks spread.
We check that your zones and firewalls really stop the paths that matter.
