The Three Counties Regional Defence & Security Cluster (3CRDSC), is an association of security and defence SMEs, originally established to significantly raise the commercial and industrial capacity of the sector across the Three Counties of Herefordshire, Worcestershire and Gloucestershire. 

The group now has a UK-wide reach, and although not exclusive, it focuses on organisations specialising in products and services for the Specialist User.

3CRDSC originated the Specialist Defence and Security Convention UK (SDSC UK - formerly 3CDSE).

The Cluster provides an industry-specific platform to connect SMEs and organisations in the defence and security sector, creating opportunities to collaborate and identify partnerships and joint ventures.


  • Offers and opportunities relating to the UK's leading specialist  defence and security expo, SDSC-UK.
  • Complimentary bi-annual in-person networking events for two people per organisation and further online seminars and events.
  • Discounted rate for additional members of an organisation to attend 3CRDSC events.
  • Enhanced access to tender opportunities through collaborations.
  • Partner offers: legal, financial, marketing and training at preferential rates.
