The Zeroed-In Podcast, by Thing-Zero
Before you can secure your OT network, you have to understand it. In this episode of the Zeroed-In Podcast, our host Olivier Bloch sits down with Dan Frechette, OT security expert and former member of the CyberX Labs team (now Microsoft Defender for IoT). Together, they unpack the fundamentals of OT visibility, asset discovery, and passive network monitoring. They also cover how modern tools like Microsoft Defender for IoT help organizations identify risks before attackers exploit them. Topics Include: • Why you can’t secure what you don’t know exists • The critical differences between IT and OT networks • Real-world OT cyberattacks like TRITON • How to passively discover every device in your plant network • Why security may actually bridge IT and OT, not divide them If you work in manufacturing, utilities, or industrial cybersecurity... this is your crash course in understanding what’s really running on your network, and how to defend it.
