Freelancer profile translated to English.
Back to original languageAbout Thomas
Cybersecurity expert with 5 years of field experience, I work with SMEs and large corporations (Thales, Crédit Agricole) on three fronts: ISO 27001 / NIS 2 compliance, post-audit hardening, and integrating AI into security processes.
What sets me apart: I combine in-depth technical expertise (security architecture, EBIOS RM risk management, ISMS) with the ability to develop custom AI connectors — automated reporting, intelligent log analysis, compliance dashboards.
I undertake short or long-term assignments, on-site (Paris / Île-de-France) or remotely.
Do you have an ISO 27001 audit to prepare, a system to harden, or a NIS 2 compliance issue? Contact me for an initial discussion.
