Back to original languageAbout Stephane
I was aSystems and Network Administratorin a group that works for various service and transport companies. During my professional experiences, I was responsible for various IT departments, virtual infrastructures under Vmware and Proxmox, and a hybrid cloud infrastructure under Microsoft Azure / Office 365. The tools and technologies used were most often open source: **EDR, SIEM, Firewall, VPN**, but I also used proprietary tools as needed (MDM, antispam, antivirus, backups). I master server operating systems as well as the implementation of network services. I am passionate about IT security, creator and player of CTF (**Capture The Flag**).
I specialized in offensive and defensive security by creating or integrating labs to train IT teams, then I launched myself in 2023 intoweb pentestingand web APIs. My latest missions: setting up an on-premise infrastructure powered by open-source services with a touch of DevOps to manage user sessions. I am also working on a Flask application to introduce younger people to ethical hacking.
