The SANS Institute 2026 ICS/OT survey finds that 34% of industrial organizations had a cyber incident affecting OT/ICS environments in the past year, up from 22% the year before (infosecurity-magazine.com, helpnetsecurity.com). industrialcyber.co describes this as the largest increase recorded since tracking began. Impact is getting worse: safety disruptions and IP theft have increased (infosecurity-magazine.com), with safety incidents doubling and IP theft rising fivefold (industrialcyber.co). Downtime occurred in 72% of events (helpnetsecurity.com, industrialcyber.co). Detection speed has declined, and only 41% of incidents were detected within 24 hours, the first slowdown recorded (helpnetsecurity.com, industrialcyber.co). Shared credential compromise and ransomware are the leading incident types (infosecurity-magazine.com), each accounting for 31% of incidents, while supply chain compromises made up 21% (industrialcyber.co). The survey also shows a gap between leadership and the plant floor. All CISOs surveyed believe their plants would keep running through an IT compromise using islanded ICS/OT or manual controls, but only 15% of frontline operators are confident they could sustain safe manual operations beyond 48 hours (helpnetsecurity.com), and 40% of respondents are unsure (industrialcyber.co). Coverage was published between 2026-11-11 and 2026-11-13.
Detalhes técnicos
- Survey base: 696 industrial security professionals responded (industrialcyber.co).
- Incident mix: ransomware and shared IT/OT credential compromise at 31% each, supply chain compromise at 21% (industrialcyber.co). Supply chain risk is increasing due to regulatory focus and geopolitical tensions (industrialcyber.co).
- Contributing factors: poor visibility into OT systems and staffing shortages (infosecurity-magazine.com). Personnel and vendor dependencies add operational risk (helpnetsecurity.com). Poor integration of ICS/OT cyber resilience into business continuity and disaster recovery programs and insufficient supply chain risk management are also cited (industrialcyber.co).
- Validation gap: only 14% of organizations conduct routine ICS-specific threat hunting or red/purple teaming, which undermines confidence in resilience plans (helpnetsecurity.com).
- Detection tooling: dedicated ICS/OT detection platforms detected 38% of incidents but remain underutilized, as budget limits restrict their deployment (helpnetsecurity.com, industrialcyber.co). Trained operators detected 20% of incidents (industrialcyber.co).
- Resilience outcomes: organizations with better IT-OT visibility and integrated resilience plans recover faster and sustain operations longer (industrialcyber.co).
Remediação
- Test regularly, including technical validation exercises such as ICS-specific threat hunting and red/purple teaming (infosecurity-magazine.com, helpnetsecurity.com).
- Build integrated resilience planning and map dependencies, including personnel and vendors (infosecurity-magazine.com, helpnetsecurity.com). Integrate ICS/OT cyber resilience with business continuity and disaster recovery programs (industrialcyber.co).
- Improve OT visibility and strengthen collaboration between IT and OT teams (infosecurity-magazine.com, helpnetsecurity.com).
- Validate manual and islanded operating assumptions with engineers, not only with leadership (helpnetsecurity.com).
- Provide formal operator training and build strong supply chain cyber risk management (industrialcyber.co).
- Build ICS/OT-specific skills internally given workforce shortages, and adopt AI/automation tools to ease operational burdens (industrialcyber.co).
- Plan for worst-case scenarios such as a vendor disappearing, since transitioning to alternative vendors may take years (industrialcyber.co).

SANS 2026 Survey Reveals Sharp Rise in ICS/OT Cyber Incidents, Slower Detection, and Increased Operational Impact
ler a análise desta fonte ocultar
The SANS Institute's 2026 State of ICS/OT Security Survey indicates a significant increase in cyber incidents affecting Industrial Control Systems (ICS) and Operational Technology (OT), with 34% of respondents reporting incidents in the past year—the largest increase recorded since tracking began. Ransomware attacks and shared IT/OT credential compromises each accounted for 31% of incidents, while supply chain compromises made up 21%. Detection times have slowed for the first time, with only 41% of incidents detected within 24 hours, contributing to more severe impacts such as increased facility downtime (72%), doubling of safety incidents, and a fivefold rise in intellectual property theft. The survey highlights critical gaps in cyber resilience, including limited capabilities to sustain manual operations, poor integration of ICS/OT cyber resilience into business continuity and disaster recovery programs, and insufficient supply chain risk management. Organizations with better IT-OT visibility and integrated resilience plans recover faster and sustain operations longer, underscoring the need for enhanced cyber resilience strategies in industrial environments.
Technical Details
The survey involved 696 industrial security professionals, revealing ransomware and shared credential compromise are the top ICS/OT threats. Supply chain risks are notably increasing due to regulatory focus and geopolitical tensions. Manual operation sustainability beyond 48 hours is low (15%), with 40% of respondents unsure, posing operational risks if automated systems fail. Detection is most effective through ICS-specific tools (38%) and trained operators (20%), although budget constraints limit detection platform expansions.
Remediation
Emphasizing cyber resilience by integrating it with business continuity and disaster recovery programs, regular testing of resilience plans, enhanced IT-OT visibility, formal operator training, and developing strong supply chain cyber risk management can reduce downtime and facilitate faster recovery. Organizations are encouraged to build ICS/OT-specific skill sets internally due to workforce shortages and adopt AI/automation tools to alleviate operational burdens. Preparing for worst-case scenarios, such as vendor disappearance, requires robust planning as transition to alternative vendors may take years.

Discrepancies in ICS Cyberattack Resilience Confidence and Preparedness Revealed by SANS 2026 Survey
ler a análise desta fonte ocultar
The SANS 2026 ICS/OT survey highlights a significant gap between industrial cybersecurity leaders' confidence in operational continuity during cyberattacks and their engineers' more cautious assessments. While all CISOs surveyed believe their plants will continue running through IT compromises using islanded ICS/OT or manual controls, only 15% of frontline operators are confident in sustaining safe manual operations beyond 48 hours. Incident frequency has sharply increased with 34% experiencing ICS/OT incidents in the past year, resulting in downtime in 72% of events, while detection speed has declined. Confidence in resilience planning is undermined by limited technical validation exercises, with only 14% conducting routine ICS-specific threat hunting or red/purple teaming. Moreover, personnel and vendor dependencies pose operational risks, and budget limitations restrict the deployment of dedicated ICS/OT detection platforms, which, despite detecting 38% of incidents, are underutilized. The report urges enhanced collaboration between IT and OT teams and regular resilience testing to improve cyber incident response and recovery.

OT Incidents Reach a Third of Industrial Organizations, SANS Reports
ler a análise desta fonte ocultar
A recent survey by SANS Institute shows a significant increase in cyber incidents affecting OT and ICS environments, rising from 22% to 34% in a year. The impact of these incidents has become more severe, with increases in safety disruptions and IP theft. Shared credential compromise and ransomware are the leading incident types. Poor visibility into OT systems and staffing shortages are key contributing factors. The report emphasizes the importance of regular testing, integrated resilience planning, and dependency mapping to enhance security posture.
