Stefan Frei refines and exercises his pentesting, consulting, and security research skills daily, for more than a decade. After several years with the ISS X-Force, he decided to go for a PhD to combine academic research with his experience gained in the field. His research interests are the vulnerability ecosystem, security econometrics, and networking security. As a licensed helicopter and fixed wing aerobatic pilot he is used to look ahead and think out of the box. He is a frequent contributor to security conferences, such as BlackHat or FIRST.
