CONFidence is an annual IT security conference that will take place on 28-29th May, 2013 in Krakow. This is one of the biggest and most valuable conference in Central and East Europe. This event is famous not only from the good quality of presentations, but also (maybe most of all) from the great atmosphere of the conference itself and the after party 🙂
A lot of great speakers will attend to the conference this year. Details can be found here.
