A lot of us have one, without even noticing: the challenge that started as a joke and turned into years of work.
For Razvan Ionescu, our Head of Offensive Security Services, it was a bet with a former colleague. Who wins? First one to earn the GIAC Security Expert (GSE).
Then COVID froze the exams right before his final lab. (Brutal timing.) He kept going. Today he’s GSE #298.
Ask him what stuck and he forgets about the badge to talk about how systems really break.
The bet got him started. The learning is what he’d tell you to chase.
