Founder & Principal Security Consultant

I'm a Microsoft Security specialist, and I live in the detail of the defender's craft — hardening identity, hunting threats, and tuning the Microsoft security stack until it works as one. I pair hands-on engineering with a teacher's instinct, writing and speaking widely in the security community to make hard concepts land.
That depth is recognized by Microsoft itself: I hold the Microsoft MVP award in two security categories — a rare double that mirrors how I work end to end, from the identity perimeter to the detection that catches what slips through.

Robbe writes and speaks widely in the security community through Hybrid Brothers — long-form posts, public talks, and open community projects, outside the day-to-day of Cerberus.
