Profile
Cybersecurity consultant, I bring 14 years dedicated to the operational security of sensitive environments and 10 years of delivering viable projects across our territories.
I support executive management and executive committees in mastering their cyber risk. By translating technical challenges into informed and prioritized operational, budgetary, and organizational decisions, I enhance the maturity of their defense framework.
My expertise includes:
- Incident response and cyber crisis management.
- Infrastructure hardening (Active Directory, backup systems, hybrid environments).
- Application security by design.
- Resilience-oriented architectures.
- Integration of AI systems applied to attack detection.
My background combines:
- Architectural vision and field expertise.
- Operational management in sensitive environments.
- High technical standards limiting technical debt.
- Defensive and ethical offensive approach.
I have operated systems exposed to high criticality (up to 6,000 users, 16 sites, 8 countries), facing APTs, ransomware, O365 / SharePoint compromises, and internal data exfiltration.
I master the following frameworks: ISO 27001, CaRE, NIS2.
I support executive bodies to:
- Conduct risk assessments to objectify threat scenarios and prioritize cyber investments.
- Structure governance aligned with regulatory requirements.
- Strengthen business continuity and organizational resilience.
- Significantly reduce risk exposure.
- Increase detection and remediation capabilities.
- Preserve reputation, partner trust, and company value in the event of a major incident.
I work with executive committees. I anticipate and secure companies and organizations ahead of major crises to protect their operations, reputation, and strategic value.
I also contribute to upskilling your teams (awareness sessions, workshops, crisis management exercises) to sustainably anchor security mechanisms.
I recently organized and coordinated the REMPAR25 crisis room exercise, reproducing real-world cyber crisis management conditions involving multiple departments of an OIV entity composed of 2.200 FTE.
I support executive teams in anticipating and internally managing cyber-origin crises. In case of crisis, the organization can rely on my expertise within the cyber crisis management plan.
