A new CISA‑led guide explains how zero‑trust security can be applied to operational technology, balancing cyber defence with safety and system availability
CS4CA USA Summit Speaker Daryl Haegley on Zero Trust and OT VisibilityCritical infrastructure operators face constant cyber probing from state adversaries targeting energy, water and industrial systems. A U.S. Air Force cyber resiliency leader explains why zero trust, IT-OT separation and stronger anomaly detection are essential to defend mission-critical operations.
Recent Cybersecurity Conferences Highlight Resilience and Shoring Up Critical Infrastructure SystemsLearn how recent cybersecurity conferences focused on resilience and shoring up critical infrastructure systems spotlight the need for virtual segmentation, OT visibility and zero trust adoption.
CS4CA Summit Highlights How IT, OT Teams Can Come Together to Implement Zero TrustThe first step in securing OT networks is gaining full visibility into all assets, then segmenting them based on workflows rather than physical locations. Today, AI can reduce much of that workload. But IT and OT teams will need to meet in the middle - on the process boundary, not the network diagram.
The Evolving Healthcare Cybersecurity Landscape Healthcare organizations face unprecedented cybersecurity challenges in 2025. With operational technology (OT) environments increasingly targeted and the convergence of IT and medical systems creating an expanded attack surface, traditional security approaches are proving inadequate. According to recent statistics, the healthcare sector
