About Xavier

Hello everyone!

Being passionate about "hacking" for many years now, I naturally chose to make it my profession, and this led me to the position of Pentester auditor.

Being also very attracted by the sharing of knowledge, I give training and courses ranging from training in secure development to SI attack and internal audit/Red Team methods!

Don't hesitate and stay secured!
