The CNI Cyber Security Summit 2025

As the UK’s Critical National Infrastructure (CNI) faces a rising tide of sophisticated cyber threats, from geopolitical tensions to ransomware attacks driven by criminal organisations, resilience has never been more critical.

While new technologies continue to evolve, it is the collective strength of people, partnerships, and preparedness that forms the backbone of CNI security.

Collaborating Against Critical Threats: Securing the Future of UK CNI

The theme of the 2025 CNI Cyber Security Summit focused on real-world threats facing CNI organisations and look at ways in which they can collaborate to protect themselves against ever-evolving risks.

From the increasing complexity of nation-state attacks from countries like China, North Korea, and Russia to the vulnerabilities within global supply chains, the summit explored the most pressing challenges facing the sector today.

"Bridewell’s CNI Summit is my only must attend event each year. The carefully curated list of speakers, workshops and attendees in the inaugural summit were second to none. You’ll find bigger events, and you may find events which cover more topics, but you’ll seriously struggle to find anything which is more worthy of a day of your time.”
