Now in its third year 3CDSE has grown significantly from its origin as a networking forum to introduce SME’s to procurement decision-makers and influencers in the MoD and Law Enforcement agencies and to foster commercial discussion between SME’s and Primes.


3CDSE 2019 will be engaging both UK and foreign intelligence, including the further Five Eyes of USA, Canada, Australia and New Zealand, and European intelligence agencies, as well as Government and Law enforcement agencies.


The theme of 3CDSE is Innovation, with a focus on cyber security, hardware and vehicles, UAV and counter-UAV, technology and communications.

The Three Counties of Herefordshire, Worcestershire and Gloucestershire comprise the hub of the UK’s defence and security industry – the “golden triangle” – with MoD based in Herefordshire, Qinetiq and the Malvern Cyber Cluster in Worcestershire and GCHQ in Gloucestershire, plus all the satellite industries which have grown up around them.

Several sources record that 90% of the UK’s defence and security innovation has its home in this triangle and at 3CDSE, there is a focus on business development.

"It's an opportunity to meet with end users and hear about the problems they are facing, the technology they are using and what does and doesn't work."

— Nicholas Hill, Plextek CEO

3CDSE is a unique showcase for this hub of innovation to share new ideas and host those involved in the industry nationally and internationally on their “home turf”. The show brings together senior military leading forces development and procurement, senior police engaged in the fight against cyber-crime, the intelligence and security agencies, and the industry innovators who supply them, to identify future strategies and needs.

In 2019 3CDSE will become a 2-day event with the addition of the JFC CAP SP & DE&S Special Projects Industry Day, historically held at Shrivenham and now securing a new home at 3CDSE. There will be restricted entry for this classified briefing, the first such held since 2016, individuals will need to hold an extant SC clearance to attend.

The 2018 event saw over 1000 delegates and 105 exhibitors and cemented 3CDSE’s reputation as a forum for the military, suppliers, law enforcement and security agencies to identify common interests, solutions and opportunities.

3CDSE 2018







The 2019 event follows on from the success of the first Herefordshire Defence & Security Expo HDSE, which was held in Hereford in February 2017 and which became the Three Counties Defence & Security Expo 3CDSE when it moved to its new and current home of the Three Counties Showground, Malvern in 2018.
