Stakeholder
Senior Leadership
For leaders deciding which OT risks need immediate action, planned investment or explicit residual-risk acceptance.
Decisions and constraints for this role
Questions likely to need resolution
- operational risk
- project delays
- regulatory exposure
- reputation
- investment justification
- prioritisation of improvement work
Review focus
Meridian sets out the risks, available evidence and improvement options so leaders can decide what needs action and when.
Work and outputs
Engineering work
- Turn OT cybersecurity uncertainty into clear risk themes, practical priorities, and evidence-based decisions.
- Separate immediate exposure concerns from longer-term improvement work and project assurance needs.
- Explain trade-offs around resilience, regulatory exposure, investment timing, and brownfield implementation constraints.
- Provide leadership-ready summaries without overstating what any single control or project can achieve.
