News
(Keng) Panik am Netz!
Less is more! This is pretty much our philosophy regarding cryptoPartys. We'd rather see less people attending a cryptoParty of ours and dragging off with some new knowledge and implementing it, than a big crowd going home without having gained that much of new intel.
Our latest cryptoParty / security awareness conference in Ettelbréck ended exactly like the first one described above: 15 people - so no terrible big crowd - who had learned something that evening.
Topics like Apps to secure SmartPhones, Browser alternatives, Tor and much more were part of the program.
You might want to see the presentation, read the summary of recommended tips or simply have look at some impressions from the evening, so please visit the according wiki page. ;)
