About Arnaud

18 years in SSI and business continuity, including 15 years of consulting and support in the banking, telecom, national defense, and public service sectors.

My last position as an employee was Group CISO of a large ESN (10,000 employees).
In 3.5 years, I led our French activities to a sufficient maturity level to obtain the ISO27001 certification required by many clients.
The main projects involved implementing risk management, audit, and control processes, managing the ISMS, and on a more operational level, incident management (including SIEM/SOC), vulnerability management, awareness training, integrating security into projects, and strong authentication.

A first career part of about ten years of expertise in systems, networks, and IT architecture gives me full legitimacy in discussions with CIOs or Operations Management.

I maintain this dual SSI and IT expertise.

I can support you on an ISO27001 certification project, your risk analysis, or your SSI maturity assessment, as a part-time CISO.
