CISO at Thales securing operational systems, cloud environments, and AI tools for engineering.
FranceWhat I'm looking for
At Thales, I’m responsible for information systems security across the TSGF operations domain and beyond the Business Line. My current work includes securing cloud environments and AI and agentic tools for engineering.
At NATO Allied Command Transformation and OTAN, I coordinated cyber capability development programmes and projects. That work helped operationalize cyber defence as a domain of confrontation.
At ANSSI, I worked on certification of security products and trusted service providers, security accreditations for observation and listening satellites, and support for government programmes. I also represented the Agency in international bodies.
Earlier in my career, I served in the armed forces, including as a unit chief supervising more than 100 people. I hold CISSP and CISM certifications and value collaboration between teams in tackling complex cybersecurity challenges.
