"We didn’t even call it OT back then."
That one line says a LOT.
Because OT security isn’t new we just finally have a name for it.
And more people are paying attention.
In Episode 72, Aaron C Crow sat down with Patrick Gillespie, OT Practice Director at GuidePoint Security, to talk shop on:
✅ How legacy systems create modern risks
✅ Why patching isn’t the fix-all for OT
✅ Balancing availability, safety & security
✅ The real challenge: people and process, not just tech
✅ Breaking into OT — and building talent for the future
From freight trains to firewalls...
Patrick’s lived it.
And now he’s helping orgs and veterans thrive in this world.
Whether you’re new to OT or knee-deep in controls,
this one’s packed with lessons you can use right now.
