The 2025 OT Security Financial Risk Report

Worst-case scenarios for global financial risk from OT cyber incidents are estimated at as much as $329.5 billion.

In a severe, but plausible scenario (a 1-in-250-year tail event), global OT cyber losses could reach $329.5 billion, with $172.4 billion specifically from OT-related business interruption.

The three OT cybersecurity controls most correlated with risk reduction are: Incident Response Planning (up to 18.5% average risk reduction), Defensible Architecture (up to 17.09%), ICS Network Visibility and Monitoring (up to 16.47%).

Indirect losses impact up to 70% of OT-related breaches.
