Quantifying OT Cyber Risk in Financial Terms: Executive Action in Critical Energy Infrastructure

Wednesday, October 7, 2026
2:05 PM - 2:35 PM
Focus Track (Strategy Room)

About This Session

As energy systems become more distributed, digital and interconnected, operational technology is now central to the resilience of critical infrastructure. Wind, solar, battery storage, grid-connected assets, gas, data centres and other energy environments depend on complex OT ecosystems that were often not designed with today’s cyber risk in mind.

For many operators, the challenge is no longer whether cyber risk exists. The challenge is understanding what is connected, where exposure sits, which risks could affect operations, and how to translate technical findings into decisions that boards, investors, compliance teams and asset managers can act on.

This session will present a practical, vendor-neutral approach to OT cyber risk management across critical energy infrastructure. It will explore how organisations can move from fragmented asset lists and one-off assessments towards continuous visibility, risk prioritisation, compliance evidence and executive reporting.

The presentation will focus on the operational realities of energy infrastructure: distributed sites, mixed vendor environments, limited local cyber expertise, evolving regulation and the need to protect uptime, safety, compliance and business continuity. Rather than focusing on a single technology or product, the session will give attendees a repeatable framework for connecting OT visibility with cyber resilience and business action.
