About me


I started this weblog in 2010 to tell stories about things I come across during security research I perform in my free time. To create more awareness about insecurity in computer systems and their threat to our daily lives. But also to take lessons from it, and learn how you can protect yourself against risks.

In my professional life I’m an IT security consultant and ethical hacker and help organizations te get more secure.
