Jonas Lejon is an amazing mind in the Swedish security world. A

great entrepreneur, hacker, and security-expert!

We had the pleasure of talking with him in this episode of Security Headlines.

he wanted to specialize in security so he packed his bag and headed over

to the capital city to work more in-dept with security. He wanted to

go deeper and deeper, so spent his extra hours learning the assembly programming

and getting into the low-level brain of the computer system. He managed

to land a job working for the Swedish version of NSA.
