About Marc-Arthur

Hello,

Trilingual cybersecurity consultant (French, English, Spanish), I support companies in strengthening their operational security, their IS security governance, and their vulnerability management within critical and demanding environments.

Currently on assignment at BNP Paribas as an Operational Security Engineer, I work on sensitive applications in production, particularly SWIFT environments, with responsibilities in security assessments, patch management, critical vulnerability remediation, and maintaining the security of infrastructures.

My background has also allowed me to work on governance, compliance, and risk management topics at Orange Business, supporting major clients such as LVMH and Engie on issues related to GDPR, ISO 27001, and ISO 27005.

I possess a strong ability to adapt to complex and multicultural environments, as well as a results-oriented, pragmatic, and collaborative approach. I work on both technical issues and coordination, analysis, and team support topics.

Key skills:
• Vulnerability management & remediation
• Patch management & operational security
• IS security governance & compliance
• Security audits & risk management
• Tanium, Nessus, Microsoft Sentinel, Ansible, SCCM, PowerShell
• Critical environments & production

Available for freelance missions remotely, hybrid, or on-site, I am open to discussing your needs to provide reliable, proactive, and business-oriented cybersecurity expertise.
