Demystifying zero trust in OT
What happened
The article lays out why OT (operational technology) must move toward zero‑trust as OT/IT convergence and remote work increase exposure. It highlights that many industrial control systems were built to implicitly trust internal devices and that OEMs often require remote access for warranty and maintenance, making access controls an operational dependency. Watch whether suppliers push for broad remote rights in contracts and how buyers enforce continuous verification
Why the category manager should care
Require segmentation, MFA, logging and attestations for any vendor remote access rather than accepting broad access clauses
Key facts
- OT/IT convergence increases external access to formerly air‑gapped OT systems
- ICS often have multi‑decade lifecycles, so access controls must accommodate long device life
