Matthias Deeg is interested in information technology - especially IT security - since his early days and has a great interest in seeing whether security assumptions in soft-, firm- or hardware hold true when taking a closer look. Since 2007 he works as IT security consultant for the IT security company SySS GmbH and is head of Research & Development.

His research results concerning different IT security topics were presented on different national and international IT security conferences (e.g. Black Alps, BSidesVienna, Chaos Communication Congress, CONFidence, DeepSec, Hacktivity, Hack.lu, PHDays, Ruxcon, t2, ZeroNights). He also published several IT security papers, security advisories, and security-related YouTube videos.
