Summary
🤩
Rockstar🎓
Top SchoolLeon S is a seasoned physical security leader with 9 years of experience designing and operating security programs for datacenters and large campus environments, currently managing Campus Security at Booking.com in Amsterdam. He blends a deep practical grasp of risk management (MSc in Security & Risk Management) with people leadership and a penchant for automation—optimizing control center operations to drive cost reduction, ROI, and measurable compliance gains. Leon created a pragmatic service delivery method that maps organizational context to ISO 31000/27001-aligned controls and daily-to-strategic reporting. Unusually for a physical security manager, he contributes to open-source security tooling and reverse-engineering projects (Python, IDA, Ghidra), including work on an undetected Chromedriver focused on bypassing bot mitigations, which demonstrates hands-on technical skills in DevOps and NetSec as well as operational security.
