Editions of DSEI UK
Each edition has its own exhibitor list with its own record count. Past editions are not leftovers — exhibitor bases are sticky, so a completed edition is a reliable read on who returns next time, and it is available now rather than weeks before doors open.
Related security & defence shows
The same buyers cluster at several events across the year, and the overlap between them is smaller than most people assume. Covering two or three usually beats buying one list and hoping.
