About Julien

I've worked in cyber security for many years now and in many aspects of it. I am now using this acquired experience in large companies to explore new horizons as a full-time freelancer. I've been doing this for many years as a part time but this now my main activity. I'll be able to help you and your company on many projects from penetration testing/red team/source code audits to other type of projects like architecture audits and cloud security.

I also have acquired many certifications and knowledges ( OSCE3/OSCP/CEH) from my experience and always open to teach and help your team if they have any questions.

If your interested and have a project for me don't hesitate to contact me and I'll will answer quickly.
