Diamond Systems at DSEI 2025

This September, our Business Development team travelled to London for DSEI UK, the world-leading defence and security exhibition held biennially at ExCeL.

DSEI is unlike any other event – a global forum where governments, national armed forces, industry leaders, and academics come together to explore the latest innovations shaping the future of defence and security. The sheer scale and energy of the exhibition is something that needs to be experienced in person.

Representing Northern Ireland on the Global Stage

It was fantastic to see Northern Ireland so well represented at DSEI, with a superb Invest Northern Ireland stand showcasing the strength and diversity of companies from across the region. From advanced manufacturing and engineering to cyber security and communications, local firms stood shoulder to shoulder with global players.

As members of ADS Group NI, Diamond Systems is proud to be part of this ecosystem, supporting aerospace and defence clients with trusted, cyber-secure, and fully accredited life safety and security solutions.

Building Connections and Sharing Expertise

Throughout the event, our team met with existing clients, industry partners, and new connections from across the defence and security community. These conversations underline the importance of collaboration and innovation in keeping people, assets, and infrastructure safe in a fast-changing world.
