Key Takeaways People

In nearly all organizations surveyed , CISOs are now or will soon be responsible for OT cybersecurity . Also noteworthy , more OT cybersecurity professionals now come from IT security leadership rather than the operations team .

Cybersecurity Incidents

While the number of organizations that did not incur a cybersecurity intrusion improved dramatically YoY ( from 6 % in 2022 to 25 % in 2023 ), there is still significant room for improvement . In fact , three-fourths of OT organizations reported at least one intrusion in the last year , and nearly one-third of respondents reported being victims of a ransomware attack ( 32 %, unchanged from 2022 ). Intrusions from malware and phishing increased 12 % and 9 %, respectively .

The Impact of Intrusions

When a cyberattack occurred earlier this year , nearly one-third ( 32 %) of respondents indicated both IT and OT systems were impacted – up from only 21 % last year . To combat intrusions , OT professionals are increasing cybersecurity solutions in their industrial networks .

Advanced persistent threats , internal network segmentation , and secure remote access have increased the most , while threat intelligence has declined as a solution .

How Cybersecurity Helps

While survey findings reveal that cybersecurity solutions continue to aid in the success of most ( 76 %) OT professionals , particularly by improving efficiency ( 67 %) and flexibility ( 68 %), the data also shows that solution sprawl makes it more difficult to consistently protect their converged IT / OT landscape .
