Dr. Stefan is a security consultant who enjoy security problem solving and to help customers continuously improve their security. To educate is a passion that Stefan practices in a wide range of activities, from University lecture halls, during security testing debriefings, work-shops or during lunch time with his colleagues.

Stefan derives the base of this knowledge from a varied mix of assignments, for instance security tests of connected devices, non-standard fulls-stack solutions and security code reviews. To be at the fore-front of any field is a major driver for Stefan.

When not on assignments, Stefan enjoys to write tools to help out colleagues in the field and to automate repetitive tasks.
