- A strong understanding of AI-related cyber threats, emerging attack vectors and associated controls.
- Experience engaging directly with regulators, Boards and executive committees.
- Outstanding communication skills and the ability to simplify complex technical concepts for non-technical audiences.
- A pragmatic, delivery-focused approach suited to fast-paced and evolving environments.
- Why Consider This Assignment?High-profile interim leadership role with significant executive exposure.
- Opportunity to influence long-term cyber strategy and security architecture.
