OT Ransomware: Are You Prepared?
The numbers paint a stark reality: Downtime from an ICS/OT ransomware attack costs an average of $4.73 million per incident—and that’s before factoring in safety risks, regulatory penalties, and reputational damage.
Yet, many organizations remain unprepared:
- 52% of ICS facilities lack a dedicated incident response plan
- 20% of ICS operators are unaware if they even have one
- 45% of ICS network compromises stem from IT networks, where attackers exploit weak IT-OT integrations to infiltrate industrial systems. Despite this, many organizations still rely on IT-centric security controls that fail to address ICS-specific threats—leading to false positives, operational disruptions, and ineffective defenses.
Unlike IT breaches that lock up data, ICS/OT ransomware shuts down operations—disrupting power grids, crippling supply chains—putting lives at risk. Attackers don’t just want access; they leverage operational importance for maximum extortion.
Will your organization be ready to respond?
Your Guide for an OT-Specific Incident Response
IT incident response plans aren’t built for the realities of ICS/OT environments. This white paper provides a practical, engineering-driven framework for developing ransomware response playbooks tailored to critical infrastructure — emphasizing life safety, operational continuity, and realistic ICS tabletop exercises. With a focus on cross-disciplinary collaboration and sector-specific threats, the guide outlines how to detect, contain, eradicate, and recover from ransomware attacks without compromising industrial operations. It also underscores the importance of treating response plans as living documents — continually tested and refined as environments and threats evolve.

Learn from Those Leading the Front Lines
Available to watch OnDemand starting May 16, this webcast features top ICS/OT security experts — Tim Conway, Robert M. Lee, Jason Christopher, and Lesley Carhart — discussing how to protect industrial operations against the growing threat of ransomware.
You’ll hear about the real-world business and safety consequences of an attack, how to apply the Five ICS Cybersecurity Critical Controls, and where to invest in training to improve your team’s readiness. Whether you’re building or refining your OT ransomware playbook, this session will equip you with the insight needed to lead a confident, real-world response.
OT Ransomware Response Starts with Prepared People
Defending against ICS-specific threats requires more than general cybersecurity knowledge—it demands specialized OT expertise and strategies that enhance security without disrupting operations.
SANS ICS Security training and GIAC certifications equip engineers, analysts, responders, and security leaders with the hands-on skills to protect industrial environments across the full threat landscape. From foundational ICS concepts to advanced detection and response, these courses prepare professionals at all levels to meet modern ICS/OT cyber threats head-on—while empowering their organizations to detect, respond to, and recover from attacks with confidence through a proven, structured learning path.
