Audience and statistics

Another reason why DSEI has become a big platform for supply and demand is the fact that there’s a lot of effort put into devising countermeasures against cyber-crimes. Security is one of the big subjects with 6 seminars tackling current challenges while CYBER HUB dives deep into subjects like electronic warfare, telecommunication systems and high-tech surveillance. The audience breaks down into influencers, decision makers, military buyers and a whole line-up of VIP guests.
