Model flows before enforcing boundaries
Trust shaped around operations
Industrial Segmentation & Zero Trust
Redesign zones, conduits, identity, privileged access, remote connectivity, and detection so compromise is contained without breaking the processes the network exists to support.
Operational context
The problem
Why this is an architecture challenge
Flat networks and inherited remote-access paths allow routine dependencies to become enterprise-wide exposure. Conventional IT segmentation often ignores industrial protocols, availability, vendor support, and maintenance realities.
Business and operational drivers
What brings organizations to this work
- Contain cyber and operational disruption
- Modernize remote and vendor access
- Make trust boundaries visible and governable
- Support brownfield modernization without unsafe network change
What SecurePlane assesses or designs
Evidence across the operating environment
- 01Purdue levels, zones, conduits, routing, and firewall policy
- 02Interactive and machine identities across OT boundaries
- 03Vendor, engineering, and privileged access workflows
- 04Protocol and application dependency behavior
- 05Detection coverage and operational response paths

Architecture approach
From operational context to governed decisions
Define zones by function, criticality, and consequence
Use identity and device context where technically supportable
Place inspection and broker services at deliberate trust boundaries
Pilot rules, observe impact, and validate rollback with operations

From architecture to implementation
Engineering proves the path
Segmentation is introduced through flow discovery, representative policy, monitored pilots, maintenance-window planning, and explicit rollback—not through an untested firewall-rule migration.

How the work proceeds
SecurePlane develops the target segmentation model, validates critical flows with site teams, prototypes representative controls, and sequences rollout around operational windows.
