International Security Expo is the UK's leading annual exhibition and conference for the global security industry, held at Olympia London on 29-30 September 2026. The event brings together over 10,000 professionals from more than 100 countries, including 300+ exhibiting brands, to address the full spectrum of physical security, counter-terrorism, cyber security, border protection, and critical infrastructure resilience. It is co-located with International Cyber Expo and enjoys formal backing from UK Defence and Security Exports and the Department for Business and Trade.
International Security Expo (ISE) is an annual two-day exhibition and conference held at Olympia London in the United Kingdom. It is organised by Nineteen Group and serves as the UK's premier gathering for security professionals, government officials, policymakers, and technology suppliers working across physical security, counter-terrorism, border and homeland security, cyber security, and critical infrastructure protection. The 2026 edition will be held on 29-30 September 2026. It is co-located with International Cyber Expo (ICE) and formally supported by UK Defence and Security Exports and the Department for Business and Trade.
International Security Expo was established by Nineteen Group as a successor to earlier UK security trade events, positioning itself specifically at the intersection of government security requirements, critical national infrastructure (CNI) protection, and international industry. Its venue, Olympia London, has hosted the event consistently, providing a central London location easily accessible to government, law enforcement, and diplomatic communities. Over successive editions, ISE has built a distinctive identity centred on its international delegations programme and its co-location with International Cyber Expo, reflecting the convergence of physical and digital security.
For 2026, ISE has announced Figen Murray OBE, the initiator and lead campaigner for Martyn's Law (the UK's Protect Duty legislation on venue security), as the new Chair of the event and head of the Advisory Council. The 2026 Live Demonstrator, developed in partnership with CrisisCast, will take visitors through an immersive, narrated incident experience set inside a data centre under attack, demonstrating security products and techniques in a realistic scenario. The event continues its partnership with UK Defence and Security Exports for the International Delegations Programme. Visitor registration is free and open.
ISE occupies the late-September slot in the UK and European security calendar, arriving just after DSEI (London, biennial, September) and before Milipol (Paris, biennial, November). Its annual cadence and focus on the broad security market -- rather than purely military procurement -- distinguish it from the defence-focused events. The co-location with International Cyber Expo makes the combined event one of the few venues where physical and cyber security professionals and suppliers share a floor, reflecting the increasingly integrated nature of security threats to critical infrastructure.
Visitors are security managers, risk and resilience professionals, procurement officers, law enforcement and government officials, and heads of security for corporates, public venues, critical infrastructure operators, and government departments. The International Delegations Programme, backed by UK Defence and Security Exports and the Department for Business and Trade, brings vetted purchasing delegations from international markets to the show. Exhibitors include global brands such as Abloy, Astrophysics, Rohde and Schwarz, Smiths Detection, Rapiscan, Gallagher Security, and many specialist SMEs. 92% of exhibitors in recent editions reported meeting good-quality visitors, and 86% said they generated a good number of leads.
The event is structured across the Olympia Grand Hall exhibition floor, a co-located summit and conference, and multiple live demonstration areas. Format elements include:
Technology and topic areas: access control, video surveillance and analytics, perimeter protection, counter-drone and counter-UAV, CBRNE detection, screening and scanning, body armour and PPE, border security, smart locks and physical credentials, incident response technology, cyber-physical convergence, critical infrastructure protection, counter-terrorism policy, maritime and port security, and occupational safety.
