After a Hacking by Numbers course, participants will never again see IT security in the same light, as can be demonstrated by this selection of comments.

Instructors always are seasoned security experts, who take their experience from the field and not from textbooks. It makes all the difference. Not only does the course provide plenty of hands-on expertise, it is also much fun!

This selection of comments refers to past HBN Bootcamp sessions.
