Top Highlights
- Industrial organizations are increasingly shifting OT cybersecurity responsibility to the C-suite, with over 80% planning to place OT under CISO oversight within a year, highlighting its rise to a board-level concern.
- Higher OT security maturity correlates with fewer cyber attacks and less operational disruption, yet many organizations still struggle with visibility, segmentation, and incident response.
- Despite progress, a significant portion of organizations remain reactive, with increased detection of intrusions, longer attacker dwell times, and growing threats from sophisticated cyber adversaries.
- To bolster OT security, companies are modernizing systems, implementing network segmentation, secure remote access, and integrating OT into broader security and incident response strategies, emphasizing ongoing improvement and strategic resource allocation.
Key Challenge
According to Fortinet’s 2026 State of Operational Technology and Cybersecurity Report, industrial organizations are progressively strengthening their OT security programs, with responsibility increasingly shifting to executive leadership, notably the CISO and CSO. More than 80% plan to place OT security under CISO oversight within a year, highlighting its rise to a board-level concern. The report explains that this shift is driven by the growing connectivity of cyber-physical systems, which, although offering efficiency gains, also expand the attack surface for cybercriminals, ransomware groups, and nation-state actors. Organizations with advanced security practices—such as segmentation and threat intelligence—are experiencing fewer attacks and less operational disruption. However, despite progress, many still struggle with visibility, segmentation, and incident response, often relying on reactive measures. This is compounded by evolving regulations and increasing attacker dwell times, which threaten critical infrastructure and business continuity. Reporting these findings, Fortinet emphasizes that higher cybersecurity maturity correlates with reduced attack impacts and better preparedness, but warns that ongoing investment, strategic planning, and leadership commitment are vital to closing remaining security gaps and safeguarding industrial operations.
The report also notes a notable rise in organizations modernizing their OT systems, with 40% now using systems under five years old, reflecting a proactive approach toward digital transformation. Nonetheless, legacy systems continue to pose risks, necessitating strict patching and monitoring. Recommendations include adopting microsegmentation, zero-trust remote access, and integrating OT into comprehensive security and incident response frameworks. Fortinet advocates for a platform-based security model that consolidates threats intelligence and automates responses—crucial steps considering the proliferation of longer dwell times and increasing regulatory demands. Overall, the report underscores that while the convergence of IT and OT generates operational benefits, it also requires a robust, organization-wide commitment to cybersecurity, especially as threats evolve and attack surfaces expand, making sustained leadership and resource allocation essential for resilient industrial environments.
Potential Risks
As operational technology (OT) systems grow more interconnected and vital to business operations, cybersecurity risks escalate accordingly. When industrial security maturity rises without proper oversight, cybersecurity can suddenly become a board-level concern—something Fortinet highlights. If your business neglects this shift, malicious cyberattacks could disrupt production, compromise safety, or steal sensitive data. As a result, operational downtime costs skyrocket, reputation takes a hit, and regulatory penalties become likely. Therefore, ignoring the growing importance of OT cybersecurity at leadership levels leaves your entire enterprise vulnerable to costly, damaging breaches—an outcome no company can afford.
Possible Remediation Steps
Timely remediation in operational technology (OT) cybersecurity is crucial because delays can lead to significant operational disruptions, safety hazards, and escalating security risks. As industrial security maturity advances, it is vital that organizations prioritize swift response and correction to maintain resilience and trust at the executive level.
Mitigation Strategies
-
Rapid Detection
Implement continuous monitoring tools to identify vulnerabilities or breaches promptly. -
Prioritized Response
Develop and follow clear incident response plans emphasizing quick action on critical issues. -
Patching Procedures
Regularly update and patch OT systems to address known vulnerabilities without delay. -
Segmentation
Isolate OT networks from other enterprise systems to contain breaches. -
Automated Remediation
Use automation to accelerate response measures, such as shutting down compromised assets. -
Training & Awareness
Educate staff on recognizing and addressing security incidents swiftly. -
Regular Testing
Conduct frequent drills and simulations to ensure readiness for prompt remediation. - Incident Tracking
Maintain meticulous logs to analyze response efficacy and prevent recurrence.
Ensuring these steps are followed efficiently enhances industrial security maturity, aligning operational resilience with board-level priorities.
