What to expect at DSEI - Defense Systems & Equipment International

Defense and security events are formal and often restricted. Badge checks, export rules and confidentiality shape what can be shown and discussed, and many conversations are with long-term partners.

Over four days, traffic usually peaks on the first two days and thins out on the last one. The quieter final day is a good time for longer conversations, visiting other stands and meeting suppliers. Expect most visitors to be government and military procurement officials and their colleagues, often with a short list of suppliers they want to see.

How exhibitors should prepare for DSEI - Defense Systems & Equipment International

Here is a working timeline counted back from the opening day, September 7, 2027:

1. 16 weeks before (May 18, 2027)
   Confirm your booth space and read the exhibitor manual. Book hotels in London while rates are still normal.
2. 8 weeks before (Jul 13, 2027)
   Order booth services (power, internet, furniture, cleaning) before the early-rate deadlines, and send graphics to print.
3. 4 weeks before (Aug 10, 2027)
   Ship freight to the advance warehouse if the organizer offers one. Book meetings with the visitors you most want to see. Set up lead capture and train the team on it.
4. One week before (Aug 31, 2027)
   Confirm freight arrived, share the staffing schedule, charge every device, and test your lead capture app with Wi-Fi turned off.

Preparation tips for defense and security shows

• Check registration, security clearance and export control rules for products you plan to display.
• Prepare unclassified briefing material suitable for a general audience.
• Schedule meetings with integrators and procurement officials in advance.

Booth tips for DSEI - Defense Systems & Equipment International

• Keep displays professional and factual; claims are scrutinized.
• Know which information you may and may not share at a public stand.
• Collect only professional contact details, and respect visitors who prefer not to have their badge scanned.
• Plan shifts of three to four hours. Standing and talking for four days wears people out, and tired staff let good leads walk past.
• Capture every conversation the moment it ends: scan the badge or card, add a one-line note about what the visitor needs, and rate the lead hot, warm or cold. Notes written that evening are already half forgotten.
