Operational Technology (OT) environments have become extensively connected over the past two decades due to IT/OT convergence, vendor homogenization, and the economic and operational benefits of remote monitoring and control across wide geographic areas. This widespread connectivity, driven by needs for efficiency, cost savings, real-time telemetry, and regulatory compliance, has introduced significant security exposure as many systems rely on legacy technologies with limited security, lack budgets for modern protections, and often require persistent remote access for vendor support. Consequently, critical infrastructure and industrial control systems face escalating cyber risks, with attacks increasingly automated and leveraged by AI, posing complex challenges for securing and managing these interconnected, yet often under-resourced, environments.
