Honeywell released its 2026 OT Cybersecurity Benchmark Report on Tuesday, and the findings point to a disconnect between how industrial organizations rate their operational technology (OT) security programs and how prepared they actually are. The report also examines AI’s impact on OT security.
Among 603 surveyed leaders across critical infrastructure sectors, 88% characterized their OT security programs as mature or design-led, yet only 21% maintain a complete inventory of their OT assets.
Respondents worked across critical infrastructure sectors, including energy, oil and gas, healthcare, maritime, and manufacturing, with participation spanning the Americas, EMEA and APAC regions.
Visibility gaps showed up in monitoring as well as inventory. Just 33% of respondents said OT is fully integrated into a centralized security operations center, and only 20% continuously monitor more than three-quarters of connected IoT devices.
Organizations that experienced a significant OT cybersecurity incident reported an average of 16.2 hours of downtime. Among incident-affected respondents, 21% estimated downtime costs above $100,000 per hour, and 4% put losses above $500,000 per hour.
