"That OT Security Guy" is an educational initiative dedicated to bridging the gap between IT security and the physical world of Operational Technology (OT).

We believe that the best way to secure a system is to understand how it works—and how it can be broken. Our goal is to make industrial security accessible to everyone, whether you are a network engineer, a penetration tester, or just curious about how factories and power grids work.

We focus on practical, hands-on learning. No complex jargon or endless theory—just real-world skills.
