The convergence of information technology (IT) and operational technology (OT) has unlocked new efficiencies across healthcare, energy, manufacturing, and other critical sectors—but it has also dissolved the air gaps that once shielded operational systems from cyber threats. Today, a single compromised endpoint can cascade from the enterprise network into the systems that run infusion pumps, power grids, and production lines, placing safety and continuity at risk. This session examines the security challenges of hyperconnected IT/OT environments, where legacy devices, real-time constraints, and expanding attack surfaces demand a rethinking of traditional defenses. Attendees will explore practical strategies for visibility, network segmentation, threat detection, and cross-functional collaboration between IT and OT teams. The discussion emphasizes building cyber resilience that protects not just data, but the physical processes and human lives that depend on critical infrastructure.
