Freelancer profile translated to English.
Back to original languageAbout Julien
I work with SMEs, mid-cap companies, and scale-ups to secure their systems, ensure their infrastructure runs smoothly, and prepare them for upcoming legal obligations: NIS 2, DORA, reinforced GDPR.
These are topics that affect thousands of companies in France today, whether they realize it or not.
Specifically, I work on:
- Cybersecurity audit and compliance (NIS 2, ISO 27001, ANSSI)
- Securing your Microsoft, Linux, and cloud environments
- Implementing SOC, SIEM, EDR - your eyes on the network 24/7
- Drafting IS Security Policies, BC/DR Plans - the documents that truly protect you
Supervision and operational maintenance of your infrastructures
What sets me apart? I don't just deliver a technical service.
I make sure you understand what I've done, why, and what it means for you.
