Demystifying zero trust in OT
What happened
The article explains why 'zero trust' cybersecurity should be applied to operational technology (OT) as OT and IT converge. It notes that many OT systems were designed to implicitly trust internal devices and that remote vendor access is increasingly common, which raises cyber and operational risks. Watch for supplier‑required remote access in warranties or maintenance contracts and for the need to balance long-lived ICS equipment with newer zero-trust controls
Why the category manager should care
Treat remote OEM/vendor access as a contractual risk vector; procurement should demand defined access windows, logging and liability limits rather than accepting implicit trust
