Kevin Kumpf started out strapping steel under gantry cranes, found the crane control systems had never been updated, and has worked in OT security ever since, including leading OT security at a large US utility. He and Aaron spend this episode on the things that do not show up in a tool: safety culture, knowing what good looks like, and walking the floor.
Why an IT data center would never post a "days since last incident" sign, and why OT treats safety as the job. Two engineers at one plant who count 50 and 200 control cabinets. Ten engines on one ship, one running different. Why plants protect the most expensive asset instead of the most critical one, and the five-cent part nobody budgets for.
Then data and AI: a boiler tube failure spreadsheet that decided outage plans without ever being on a critical asset list, why AI without context is just numbers, and why a human who can check the work still matters. Aaron's zip tie that left a core switch failed for months, the only backup server sitting next to a space heater, and how to sell OT security to the business: uptime, reliability and competitive advantage, done securely.
Key takeaways- Count it yourself. If two people at the same plant give you 50 and 200, you do not have an inventory, and a tool will not settle it.
- Know what good looks like. A baseline of temperatures, flows, RPMs and who talks to whom is what makes the odd one out visible.
- Criticality is not price. Ask what stops production, including the small part and the small site on the same network.
- Walk the floor and ask what the red light means. If nobody knows, find out or remove the light.
- AI needs context and a human who can check its answer.
- Lead with uptime and reliability. Security comes along with it.
