Back to original languageAbout Tristan
I am a freelance Information Security Manager (RSSI) with 11 years of experience in cybersecurity and compliance. I support organizations in their structuring or growth phases (startups, scale-ups, tech SMEs, and sensitive sector players) that need to formalize their security without hiring an internal RSSI.
What I can handle:
- Definition of security strategy and roadmap construction
- Compliance: ISO 27001, HDS, GDPR, risk analysis (EBIOS)
- Drafting of documentation: PSSI, procedures, BCP/DRP, charters...
- Support for due diligence, client questionnaires, and external audits
- Team awareness (phishing, best practices)
- Operational management: vulnerability management, SIEM, alerts, supervision
My approach:
- Simple, useful security tailored to your maturity level
- Impact-oriented vision, not bureaucracy
- Security as a lever for client/investor trust
