Craig and Dino address one of the most overlooked problems in OT security: the IIoT devices your security tools don't automatically detect. Most OT intrusion detection platforms do a reasonable job of identifying core control-layer assets such as PLCs, drives, and motor control centers. The problem is everything else. Laptops plugged into the network, third-party devices brought in by contractors, and a growing range of connected IIoT equipment often go completely undetected. Those are the gaps where risk accumulates. Craig and Dino explain why the belief that machines are air-gapped is a dangerous myth, how PLCs acting as gateways prevent intrusion detection platforms from seeing the devices behind them, and why an asset inventory is not the same as knowing your real risk and CVE exposure in multi-vendor environments. They reframe OT cybersecurity as a process-integrity problem and show how unmanaged network activity, third-party remote access, and even routine IT security scans can quietly degrade OEE and trigger unplanned downtime that costs millions.
