The Specialist Defence and Security Convention UK (SDSC-UK), previously known as the Three Counties Defence and Security Expo (3CDSE), is one of the UK’s most diverse and innovative defence and security events.
SDSC-UK serves as a key platform for innovative technology and strategic ideas, uniting the UK’s foremost innovators to facilitate mutually beneficial commercial discussions among industry, armed forces, government, law enforcement, and emergency services.
SDSC-UK collaborates closely with the UK Ministry of Defence (MoD), particularly the Specialist Operations Command (CSOC) and the NAD Group Delivery Teams. It engages with UK and foreign intelligence, government, and law enforcement agencies.
