Petr Juhaňák - instructor

Hackerlab founder and lead instructor. Peter is ethical hacker and security professional holding CISSP, CEH and eCPPT certifications.

I began as web and PL/SQL developer. After few years I became Oracle database administrator. I was interested in technical security from the begining and I started to build hacking labs at home. Every single day I read security books or practice in my lab. That's how Hackerlab was initialy created. Now it serves as learning platform for junior ethical hackers.
