Summary

I am an experienced cybersecurity consultant with a strong background in ISO 27001 compliance, risk management, and audit coordination. I’ve worked in high-impact, international environments such as Euroclear and the Belgian Federal Government, where I led internal audits, supported ISO/NIS2 implementation, and delivered secure automation processes using tools like XSOAR and Sentinel. My technical foundation in cloud security, CI/CD, and vulnerability management, combined with my structured and proactive approach, makes me a strong fit for DHL’s information security compliance environment.
