C-suite Takes the Helm in Operational Technology Cybersecurity
Fortinet's latest report reveals a striking shift in operational technology (OT) cybersecurity, where organizational leaders are actively engaging with OT security strategies. The 2025 State of Operational Technology and Cybersecurity Report indicates a rapid increase in responsibilities for Chief Information Security Officers (CISOs) and Chief Security Officers (CSOs); now, 52% of organizations have placed these roles directly in charge of OT security, a dramatic rise from just 16% in 2022.
Growing Executive Accountability for OT Security
Notably, OT risk is now under broader oversight from the C-suite, with 95% of companies recognizing its significance compared to only 41% two years prior. This newfound executive ownership correlates with a significant enhancement in cybersecurity frameworks, leading to a decline in operational outages affecting revenue—from 52% to 42% year-over-year. By implementing advanced security practices such as vendor consolidation and threat intelligence integration, organizations are bolstering their defenses against cyber threats.
The Basics of Cyber Hygiene: A New Imperative
Organizations reporting higher security levels are also under fewer attacks from common threats like phishing, demonstrating that improved cybersecurity hygiene is critical. Enhanced training and integrated defenses have led to a notable decrease in business email compromise incidents, as firms streamline the number of OT vendors they engage with.
Future Challenges: The Legacy Systems Dilemma
However, the report doesn’t gloss over challenges. Legacy systems pose a serious risk, as many organizations still depend on outdated infrastructure ill-equipped for modern cybersecurity threats. Tim Mackey of Black Duck Software highlighted the troubling inertia of legacy devices, which cannot adapt to increasingly sophisticated attack vectors. He cautions that what was once considered a best practice can easily become a vulnerability.
Compliance and Best Practices for Optimal Security
Fortinet's report stresses the need for comprehensive network visibility and protective controls. The recommendation of segmentation according to ISA/IEC 62443 standards is foundational for integrating OT systems into Security Operations (SecOps) and aligning with incident response planning. Organizations are encouraged to adopt AI-powered threat intelligence feeds specifically designed for OT, enhancing their ability to guard against potential breaches.
As the implications of these changes resonate through various industries, the convergence of security responsibilities with executive leadership is a trend that cannot be ignored.
