Summary
Sébastien Ramella is an independent researcher, trainer and investigative journalist in cybersecurity with over 11 years of hands-on experience across systems, networks and security. He began as a systems administrator at Valeo and Thales and evolved into technical project lead roles at Solvay and Résiliences, delivering projects like 802.1x implementations and clustered Firewall/IDS solutions. Based on La Réunion, he consults for regional firms including Zeop and the local airport and has supported healthcare infrastructure security at the CHU de la Réunion.

Notably, his work blends investigative journalism with offensive-minded research, giving him a rare ability to communicate complex risks to both technical and non-technical audiences.
