Back to original languageAbout Antonin
Cybersecurity engineer, currently Technical Lead Cybersecurity Architect at MBDA France, with several years of experience in security architecture, CERT/SOC operations, and hardening demanding Windows/Linux environments.
What I bring to your projects:
- Attack surface audit & external exposure: mapping your internet exposure, identifying vulnerabilities, and prioritizing risks
- Security architecture: design and review of secure architectures
- System hardening: securing Windows/Linux, vulnerability management
- SOC/CERT operations: monitoring, EDR/SIEM, incident detection and response
- Automation & industrialization: Ansible, CI/CD (GitLab), Python scripts to streamline your security processes
Accustomed to demanding environments (defense sector), I deliver concrete and actionable recommendations, with a clear report and educational presentation adapted to non-security expert teams.
