About Julien

I secure your systems as if your business depended on it… because it does.

With over 6 years of experience in offensive and defensive cybersecurity, I support companies that want to sleep soundly… even when their infrastructures run 24/7.
My role: anticipate, detect, and neutralize threats before they become a problem.

What I bring to your projects:

Pentest (web, mobile, infra, cloud), audits that truly reveal vulnerabilities

Hardening & infrastructure security (Linux, Windows, Cloud, DevSecOps)

Implementation of SOC, SIEM, monitoring & detection tools

Risk analysis & compliance support (ISO 27001, GDPR, NIS2)

Incident response, forensics & rapid remediation

My style: pragmatic, rigorous, transparent.
I simplify what needs to be simplified, I get into the details when necessary.
No jargon, no buzzwords, only concrete and measurable solutions.

Why work with me?
Because I treat every mission as if I were the first and last line of defense between you and a cyberattack. And because I always deliver clean, documented, and directly actionable work.
