Demystifying zero trust in OT
What happened
The piece explains why OT environments need a zero‑trust security model as IT/OT convergence and remote workers increase external access. It highlights a concrete operational issue: long‑lifespan industrial control systems and required vendor remote access (for warranties and support) can conflict with zero‑trust controls. Watch whether OEMs and integrators publish tested compatibility plans or standard access procedures that can be put into LTSAs
Why the category manager should care
Treat zero‑trust as a contract design issue as much as a tech upgrade — capture access limits, verification steps and rollback duties in supplier agreements
Key facts
- OT historically air‑gapped but now increasingly connected to IT
- Operational lifecycles of ICS often far outlast typical IT refresh cycles
- OEM/service contracts commonly include remote access for warranty or maintenance
