About Julien

Professional, experienced, and rigorous profile, with over 20 years in the IT field. I am an expert in cybersecurity and infrastructure, specializing in GRC (ISO27001, ISO27002, Dora, Nis2, CRA, and AI Act). My 360° transverse vision of IT allows me to ensure the strategic protection of digital assets by defining, maintaining, and steering the implementation of information system security policies and standards. Adaptable to contexts, environments, and teams, I have worked in multiple sectors such as banking, insurance, industry, education, and military. As an expert in systems, infrastructure, and cybersecurity architecture, I also develop cybersecurity solutions.
