Back to original languageAbout Benjamin
Experienced consultant in networks & cybersecurity, I work on IT transformation projects, from the scoping phase to deployment. I have managed LAN/WLAN infrastructure migrations, SD-WAN deployments, Zscaler solutions, and XDR architectures in international multi-site contexts.
I master complex project management (structuring, multi-team coordination, risk management, budget & schedule control) while bringing strong technical expertise in Palo Alto, Fortinet, Checkpoint, Zscaler environments, and monitoring tools.
My value: delivering secure, high-performing, and scalable projects, closely aligned with business objectives and operational constraints.
