Key Market Insights:

Incidents and intrusions in OT environments are being probed far more often.
Nearly one-third of surveyed organizations reported 6 intrusions (versus 11% the prior year), and intrusion types rose across the board, showing that OT estates are experiencing more frequent, repeat compromises.

IoT/IIoT malware and device-focused attacks have surged as attackers target OT entry points.
Analysis shows a 400% increase in IoT malware attacks across industries and high ransomware exposure (ransomware affected a large share of organizations in recent reporting), underlining that insecure IIoT devices and exposed OT endpoints are primary attack vectors. Deloitte

Vulnerability disclosures and active exploitation are growing attack surface is widening faster than patching. One major review found 31% more vulnerabilities disclosed year-over-year and roughly a 20% increase in active exploitation, meaning OT/ICS components are being found and exploited faster than defenders can remediate.

Industrial sectors (manufacturing, energy/utilities) remain top targets operational disruption is now a frontline risk. Independent reporting shows manufacturing was one of the hardest-hit industries (large shares reporting ransomware in 2023), and utilities saw a major uptick in attacks (examples with 70% year-over-year increases in attacks against utilities in recent periods). This underlines the immediate physical-risk exposure for revenue-critical assets.

New defense tech & program shifts: AI/ML for adaptive detection, IT–OT convergence controls, and asset-centric zero-trust are becoming standard.
