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.
Jonas now runs his own company called "Triop" and has a lot of fun side
projects that we dig into.
