About
I'm Sijmen Ruwhof and an independent IT security researcher and weblogger from The Netherlands. In my professional life I'm a freelance IT security consultant and ethical hacker (white hat). I've been hacking computers for the last 22 years (with permission of the owners).
This channel is created to host my PowerPoint presentations I've given on conferences.
