I am a cybersec veteran with decades of practical experience (CSO, CISO, ISO) and theoretical background (CISSP, CISA, CISM, CSSLP, CCSP - from 2002 till 2023).

It used to be my work and my hobby, now it's only my hobby. My work about managing security by using own tools was presented, among other places, also at Information Security Forum and DeepSec.
