About Maxime

Hello,

As an experienced CISO/CSO with a technical background, I help organizations strengthen their resilience against cyber threats. Whether you are a sole proprietorship, a company, or an administration, I put my expertise at your service to secure your digital assets and understand your IT roadmap.

For VSEs/SMEs and public structures:pragmatic audits of your systems and networks, with efficient solutions to improve your security posture. Development or revision of cybersecurity policies adapted to your context and budget constraints.

For higher education:cybersecurity interventions in Strasbourg, designed for all audiences – from the general public to specialists. From discreet browsing to personal protection, I facilitate the understanding of all aspects of digital security.

For large companies:assignments in coordination with your SOC or CERT/CSIRT teams. SIEM deployment, threat intelligence (CTI), threat hunting, information system security policy review (PSSI), functional and organizational analyses, strategic watch, report review.

What you gain:a pragmatic approach, actionable recommendations, and support without unnecessary jargon.

Do not hesitate to contact me to discuss your needs – I usually respond within 24 hours.
