Back to original languageAbout Frédéric
Today a network and security engineer, I started by carrying out IPBX deployments, administration of storage environments, backup, virtualization, before focusing on network infrastructure (including infra servers) and network security.
I therefore know all the layers that make up the infrastructure of an information system, as well as administration issues.
My various experiences, particularly with integrators, allow me to understand different situations and to provide the right solutions, whether from manufacturers such as HP, Aruba, Cisco, Fortinet, Palo Alto, Checkpoint, Brocade, or open-source solutions like Linux/Debian, OpenBSD (DNS, NTP), OPNSense, or even Icinga2 and LibreNMS for monitoring.
My latest notable projects include: the implementation of a complete Campus-type infrastructure (LAN, WAN, Firewall, Wi-Fi), the replacement of "core network" Firewalls in a Datacenter (replacing 2 Fortinet firewall clusters undersized for the needs with a single Palo Alto cluster), and the replacement of obsolete equipment at remote sites, in an international context (documentation and technical lead for micro-network technicians on sites).
