In this special rewind episode, Dino Busalachi and Jim Cook address the messy but critical reality of implementing Zero Trust in operational technology (OT) environments.

Drawing from years of hands-on experience, they break down why traditional IT frameworks often fail on the plant floor, especially when facing flat OT networks, legacy assets, and limited change windows.

They introduce a "bucket approach" to segmenting and securing OT networks from the ground up. With real-world insights into asset inventory, process integrity, remote access challenges, and cross-functional collaboration, this episode is invaluable.

Whether you're a CISO, CTO, an OT engineer, or IT expert; this episode offers solid advice on navigating the convergence of IT and OT in complex industrial systems and environments.
