OT network segmentation and IEC 62443 zoning
We partition your OT network into defensible IEC 62443 zones and conduits — turning a flat or ad-hoc network into a risk-justified segmentation with the evidence to back it.
From flat network to zone-and-conduit
We map the current estate, group assets into zones by required security level, define and control every conduit, and derive each zone's SL-T from an IEC 62443-3-2 risk assessment — then validate the result automatically.
- Asset and flow discovery mapped onto a Purdue-aligned zone model
- Risk-derived SL-T per zone (consequence × likelihood)
- Flat-network, duplicate-IP and any-any-conduit issues identified and resolved
Evidence, not assertions
You get the zone-and-conduit diagram, the requirement-by-requirement coverage analysis, and a prioritised gap list — each control traceable to what satisfies it.
Frequently asked questions
What is OT network segmentation?+
It is dividing an operational-technology network into security zones separated by controlled conduits, so that a compromise in one area cannot move freely across the plant. IEC 62443 formalises this as zones, conduits and target security levels.
How does this relate to the Purdue model?+
The Purdue model gives the layered reference (enterprise, DMZ, supervisory, control, field). IEC 62443 zoning applies security levels and conduits to those layers. We align the segmentation to both.
What do I receive at the end?+
A validated zone-and-conduit design, the IEC 62443-3-3 coverage report, a prioritised remediation list, and a living model you can re-check whenever the site changes.
