Why OT Resilience Is Now a Boardroom Imperative
Palo Alto Networks, Tuesday, September 29th, 2026
Palo Alto Networks telemetry shows a 332% surge in internet-exposed OT devices, making industrial cyber risk a board-level issue.
The post argues the air gap that once protected operational technology is gone as industrial systems integrate with IT and cloud for efficiency, predictive maintenance and AI automation, and long-lived industrial machinery is now instrumented with IoT sensors and managed remotely.
Palo Alto Networks telemetry shows a 332% surge in unique internet-exposed OT devices and services, putting nearly 20 million OT-related assets on the public internet.
The author says this makes OT resilience an existential risk requiring board oversight.
