À propos

Introduction

Passionate about IT threats, I am a cybersecurity engineer specialized in threat detection (SOC), incident response (CERT/CSIRT), and audits. More especially, my daily work is to help organisations protect their business against cyber threats with both auditor and SecOps mindsets (hardening, SOAR, security architectures, sensors, tools, processes). In parallel, I give classes at engineering schools such as EPITA, and have been the creator of the IT security program at EFREI.
