ABOUT SDSC-UK

Built for a Changing Threat Landscape

SDSC-UK, formerly the Three Counties Defence & Security Expo, has evolved in response to a fundamental shift in global security dynamics.

Modern threats are multi-domain, fast-moving and increasingly complex. From state-on-state conflict and cyber warfare to AI-enabled operations and supply chain vulnerability, effective response demands integrated collaboration across sectors and nations.

SDSC-UK provides a platform where:

  • Defence and security priorities are explored in real-world context

  • Emerging technologies are aligned with operational need

  • Strategic relationships are formed between government, military and industry

MOD & GOVERNMENT ENGAGEMENT

Aligned with Defence Priorities

SDSC-UK works in close collaboration with the UK Ministry of Defence, including Cyber & Specialist Operations Command (CSOC) and National Armaments Director Group (NAD Group) Delivery Teams, ensuring alignment with current operational priorities and future capability requirements.

The event also engages UK and international intelligence communities, alongside government, law enforcement and security agencies , creating a secure, high-trust environment for cross-sector collaboration.

Engagement is structured to support:

  • Operational relevance

  • Strategic alignment

  • Capability-driven outcomes

Why Visit

SDSC-UK brings together the organisations and individuals shaping the future of defence and security in a highly targeted and operationally relevant environment.

The event connects:

  • Senior military leaders responsible for capability development and procurement

  • Law enforcement leading the response to cyber and organised crime

  • Intelligence and security agencies

  • Industry innovators delivering next-generation solutions

This is not a general exhibition. It is a focused forum for strategic engagement, insight and real-world collaboration.

SDSC-UK is focused on the realities of today’s evolving threat landscape, where capability must operate seamlessly across air, land, sea, cyber and space.

As defence priorities shift in response to near-peer conflict, hybrid threats and rapid technological advancement, SDSC-UK provides a forum to explore how capability is adapting to meet current operational demands and future strategic requirements.
