About Axel

I secure your critical infrastructures by adopting the attacker's perspective. SI Architect by day, Forensic Expert by night.

WHO AM I? Lead Tech and SI Architect with 5 years of experience on large-scale critical infrastructures (250,000 users, 120,000 endpoints). My approach is hybrid: I design robust architectures (Build) because I master the techniques used to compromise them (Offensive Security).

MY ADDED VALUE: Unlike a traditional architect, I don't rely solely on theory. My daily practice in Forensics, Malware Analysis, and OSINT (Top 2% globally on Root-Me) allows me to audit and harden your systems against real threats.

MY AREAS OF EXPERTISE:

1. Architecture & Cloud (Azure / M365):

- Design of secure architectures (SecNumCloud, HDS).

- Migration and security of M365 / Entra ID (Azure AD) environments.

- Hardening of workstations and servers.

- Industrialization and Performance Monitoring (DEX).

2. Operational Cybersecurity:

- Malware Analysis & Reverse Engineering.

- Digital Forensics & Incident Response (Level 2/3).

- OSINT (Open Source Intelligence) for investigation.

REFERENCES & CONTEXT: I have worked within Essential Service Operator (OSE) infrastructures, with a strong culture of sovereignty, high availability, and confidentiality.

Available for audit, architecture, or complex investigation missions.
