About Xavier

Cybersecurity analyst with hands-on experience in a SOC environment. For two years, I was operationally responsible for the security of a multi-site hospital association with 3,000 users (Association Sainte-Marie, Nice), under the direction of the CISO. My responsibilities included daily analysis of security alerts, incident qualification, management of Fortinet and Cybereason solutions, and governance: updating the PGSSI, risk mapping, user awareness training, and cyber crisis exercises. Holding a Master's degree in Cybersecurity Expert (Sup de Vinci, 2024) and bilingual in English, I work as a freelancer for companies looking to strengthen their operational security with method and rigor.
