The extraordinary IT Security Congress with top-class speakers from the USA and Europe is now taking place for the 17th time. IT Defense is different: It's not a conference with sponsors and promotional presentations, but an interesting mix of lectures that focus on content. At the same time, high-quality evening events guarantee an exchange with speakers and other participants. Especially the participants from industry, military and administration appreciate the possibility to network during the breaks and evening events. Here the IT security officers can exchange views and discuss technical issues among their peers. The IT Defense program is always a mix of very technical lectures, strategic presentations and entertaining speakers on IT security.
