OT: Control risk, achieve compliance
Operational technology (OT) now runs far more than factories – from logistics to healthcare – and its tight coupling with IT brings both efficiency and new cyber risk. This webinar distils what’s unique about OT, what regulators expect, and how to turn a mixed, legacy-heavy environment into a managed, compliant one. We explained how a critical asset inventory, zone definition and segmentation, and a pragmatic, standards-based programme aligned with IEC 62443 can help you with NIS2 compliance. We shared our experience and best practices for secure remote access, segmentation, patching windows,and lifecycle governance that respect safety and uptime constraints. What […]

What you will learn
- Why OT security is different from IT
- Real world OT challenges: insecure remote access, flat networks, protocol quirks, maintenance windows
- Management approaches that work in practice: governance, change control, maintenance planning, backup/restore,
secure remote access patterns - Standards-based programme with IEC 62443: what parts matter most (secure development/components)
- Risk & compliance in practice: asset inventory, zones & conduits, segmentation, monitoring, continuous improvement; evidence for audits (NIS2).
Watch the webinar recording and walk away with a concise checklist to make OT a source of pride—not headaches.
