Trust Me, It’s Air-Gapped cuts through OT cybersecurity buzzwords with plant-floor insights from Scott Christensen and Tom Walker of GrayMatter. Scott and Tom explore how risk-averse operational technology networks are built and how assumptions like “we’re air-gapped” fall apart in practice. Drawing on hundreds of in-the-field projects they tackle real OT cyber challenges such as outdated asset maps, flat networks, undocumented data flows, cyber insurance and the disconnect between IT and OT.This show is for engineers and leaders who want straight talk about security.
