What do you think? How much time does a potential attacker have to be detected on a foreign corporate network? How many minutes, days, hours? Appreciate!

There are exactly 56 days in which an attacker can change data, manipulate data or tap data. This is fatal, because digitization is more important than ever.

We are digital enlighteners: We raise awareness, create new impulses and encourage people to think. With a lot of wit, fresh wind and understandable for everyone.

Our presentations and keynotes have already taken place on stages at the Hannover Messe, CeBIT, re:publica, TedTalk, Code.Talks, it-sa as well as for various companies including IBM, Atos, Kyocera, LastPass, Berenberg Bank or Deutsche Telekom.
