Demystifying zero trust in OT
What happened
The article argues OT environments should move toward a zero‑trust model as IT/OT convergence and remote work expose formerly air‑gapped systems. It flags practical hurdles—long device lifecycles and OEM remote‑access requirements under warranty—that make zero‑trust a procurement and contract issue. Watch whether vendors propose architectures that require controller changes or expanded permanent remote‑access clauses
Why the category manager should care
Treat zero‑trust as a contractual verification item: confirm what remote access, patching and integration work OEMs will insist on before award
Key facts
- Notes OT device lifecycles can remain in service for long periods
- Recommends continuous verification of users and devices in converged IT/OT
- Points out OEMs may require remote access for warranty and O&M
