About Jean-Christophe

I work in two areas:

- Consulting, for which I carry out risk analysis and improvement recommendation missions. I develop this in the experience section.

and

- Training, for which I provide courses on Networks, systems, and cybersecurity in various training centers such as Supdevinci, Simplon, IPREC, Cyber Management School, and in 3 other IT schools in the Ile de France region, covering pathways from technician to network expert.

I am a lead trainer for the 2 cybersecurity paths: Secure Infrastructure Administrator (Simplon-Microsoft partnership).

The areas I cover are (not exhaustive, trainer profile available on request):

Introduction to networks, IPv4 and subnetting, network security, dynamic routing, network vulnerabilities, Windows Server, asset management, the cybersecurity path, Azure Cloud, ISO27001-27002 and 27005 standards.

In parallel, I am a GDPR consultant. I offer to support companies in their compliance.
(creation of the processing register, necessity of a DPO, impact assessment...).

I also provide one or two-day training sessions (depending on needs) on the introduction to GDPR (who is concerned by GDPR?, GDPR stakes and objectives, DPO designation, steps for compliance...).

Possibility of IT security awareness training.
