HOW TO ENGAGE
Advice, delivery, or managed service
Engage DESSS at whatever depth the work needs — independent advice before budget is committed, full delivery against an agreed blueprint, or ongoing support from the team that built it.
Consulting & Advisory
Assessment, platform selection, business case, and roadmap — before you commit budget.
Implementation Services
Full delivery to an agreed blueprint, with weekly demos and named deliverables at every step.
Integration & Migration
Connecting and modernizing the systems the work depends on, with validated data and monitored interfaces.
Managed Support Services
Monitoring, incident handling, enhancements, and release management from the team that built it.
A typical DESSS Purdue Model Segmentation delivery runs 6 steps, with the final step reached around ongoing. Complex integrations, multi-entity scope, or regulated environments extend that — the discovery session produces a dated plan for your case rather than an average.
Every step closes with named deliverables — Access model, Application dependency map, Change governance, Diagram corrections, Enforcement stages, Monitor deployment, Operations runbook, Policy design — so progress is visible, auditable, and reviewable rather than a status colour on a slide.
Yes. Integration with the systems your OT segmentation depends on is designed early and delivered with validation, monitoring, and error handling, so failures are visible and recoverable.
No. Purdue Model Segmentation is often delivered alongside the other OT, ICS & IoT Security products listed below, in a phased roadmap that avoids rebuilding earlier phases. DESSS sequences them so each phase stands on its own.
