Stefan works for the Internet Security Team at German company DATEV eG. Having started with computers and starting to be puzzled by reality in the 80s, he started out as a programmer in the early 90s. Since 2000 he has been securing networks and computers for various enterprises in Germany and Scotland.
His main focus nowadays is raising security awareness, coming up with creative solutions to security problems and discussing new ideas concerning risk intelligence and threat mitigation. When not trying to do any of the stuff mentioned above, he is either travelling, procrastinating or trying to beat some hacking challenge. Stefan also writes blog posts (in English and German) on his site https://cyberstuff.org.
