Beyond the lab
I am a 20-year-old Cyber Security student based in The Hague, Netherlands. I learn by building controlled environments where I can investigate Windows security, identity, network attacks, privilege escalation and defensive monitoring. Outside my studies, I take part in various sports and keep developing my practical security skills.
