Why OT Must Lead the Manufacturing Cybersecurity Conversation

Published on: 17th December, 2025

Katie O'Brien shares her unconventional journey from music teacher to industrial cybersecurity expert, bringing over 25 years of IT experience into the OT world.

In this conversation with Dino, Katie discusses the critical gaps in OT cybersecurity—from the lack of university programs teaching industrial security to the disconnect between IT and OT teams.

They explore why system integrators and OEMs fail to design cybersecurity into new manufacturing projects from the start, compare it to building cars without safety features, and discuss the emergence of managed services in the OT space.

Katie explains how Garland Technology helps organizations get visibility into aging infrastructure with unmanaged switches, and both hosts emphasize the urgent need for the OT ecosystem to drive cybersecurity conversations proactively rather than waiting for IT teams who may never have walked the plant floor.
