Defence and Security Equipment International (DSEI) is recognised as the world’s largest land, sea and air biennial defence and security exhibition, bringing together senior international trade and military experts from across the entire supply chain in an optimal business environment.

DSEI connects governments, national armed forces, industry thought leaders and the entire defence & security supply chain on a global scale. With a range of valuable opportunities for networking, a platform for business, access to relevant content & live-action demonstrations, the DSEI community can strengthen relationships, share knowledge and engage in the latest capabilities across the exhibition’s Aerospace, Land, Naval, Security & Joint Zones.

Why visit DSEI?
