What to Expect at the CNI Cyber Security Summit
The CNI Cyber Security Summit will return on 19th March 2026 and will once again take place in Central London.
It will bring together operators of essential services, regulators, CNI cyber security experts and technology providers, to discuss the latest threats, issues and challenges facing the CNI industry. The event will also provide an opportunity for collaboration and the sharing of insight and ideas on how to counter the growing tide of threats and adversaries.
Defending CNI: Stories from the Frontline
Cyber attacks never fail to make headlines, but rarely do we hear from the cyber security professionals dealing with these incidents.
At our 2026 CNI Cyber Security Summit, you'll hear first-hand accounts from the people defending our critical national infrastructure. Sharing their personal experiences from a range of cyber threats and challenges, you'll gain unique insight into their struggles, triumphs, and lessons learned.
As well as hearing from CNI operators, we'll be joined by regulators, researchers, and other bodies for a rounded view of the CNI cyber security landscape.
Event Speakers
Below are the speakers confirmed to-date for the 2026 CNI Cyber Security Summit, with more to be announced.
Breakout Sessions
Engage directly with leading experts in focused breakout sessions designed to tackle today’s most pressing cyber security challenges.
1. Insider Risk - Live Demo: From Alert to Investigation
In this interactive session, we’ll walk through a real-world scenario, from the moment an alert is triggered to a full investigation, showing best practices for mitigating data leaks, policy violations, and potential security threats.
2. Hiding in Plain Sight – OSINT Risks to Critical Infrastructure
Organisations invest significant sums of money to strengthen and protect their systems and data, but many continue to overlook publicly available information that can help attackers to breach their defences. Join this engaging workshop that will explore how these risks materialise and the lengths that attackers will go to.
3. Gridlock: The CNI Crisis Room
An immersive escape-room challenge where you must work with your team to unravel a coordinated cyber-attack on the national power grid before cascading failures plunge the country into darkness.
4. Bridging IT and OT: CTEM as the Foundation for Resilient Critical Infrastructure
Join us for a strategic discussion on how Continuous Threat Exposure Management (CTEM) is transforming security in Critical National Infrastructure. As IT and OT environments converge, organisations face unprecedented challenges in understanding their attack surface, managing risk, and meeting evolving regulatory demands.
"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.”
