While OT security is maturing, risk is not slowing down
What happened
Fortinet's 2026 OT security report finds organisations are reassessing maturity and reporting more intrusions, shifting many programs from optimistic ratings to more realistic ones. The survey—sourced from more than 700 OT professionals—shows increases in lower maturity bands and a higher share reporting one-to-nine intrusions, making this operationally real for buyers with OT dependencies. Watch whether suppliers produce concrete segmentation and incident-response evidence when procurement requests it
Why the category manager should care
Treat this as an operational signal: many OT estates are less mature than previously claimed, so procurement should require demonstrable controls and remediation commitments from suppliers
Key facts
- Survey of over 700 OT professionals worldwide
