What really happens when an organisation is hit by a major cyber attack and there is no playbook that fully applies?

 

 

 

 

Join us for an exclusive lunch in Westminster located in the heart of London with views of some of its most iconic landmarks. Senior security leaders from leading organisations will come together for a candid discussion on ransomware, leadership, and resilience.

Hear directly from our expert speakers. Stuart Okin, Director of Cyber Regulation and Emerging Technologies at Ofgem, will speak on the Cybersecurity Resilience Bill and the growing ransomware threat. Rob Newby, Head of Security Business Engagement and former CISO at Marks & Spencer, will share his real‑world experience of managing a major cyber attack and the lessons learned when theory meets reality.

This will be an unfiltered, in person conversation on ransomware, regulation, and the realities leaders face when plans fail and the stakes are highest. Expect candid insight, honest lessons learned, and an open discussion shaped as much by the room as the panel.
