NSIguy warns OT air-gap erosion

- NSIguy warns that OT environments are abandoning traditional air‑gaps as IT/OT converge, increasing exposure to network attacks. - He specifically urges rigorous segmentation inside OT networks because lateral movement risks grow when controllers and HMIs are reachable from IT. - The practical fix he recommends is designing segmented zones and enforced boundaries between IT and OT at the network layer.
