About Sébastien

With 12 years of experience at Thales and in critical systems, I position myself as a software cybersecurity expert for your systems - From risk analysis, through design, secure development, auditing, with mastery of workload and expected quality. I bring cutting-edge technical expertise in cybersecurity for the build or run of potentially complex projects requiring specific analysis requirements.

I act as a senior cybersecurity auditor for high-value complex systems, covering a multitude of facets, supports, or domains (critical infrastructure, medical systems, cloud management systems, etc.).

In parallel or after audits, I act as a technical referent for the overall improvement of cybersecurity for given projects (advice, development examples, popularizations, communication of past or ongoing experiences, etc.).

Conceptual analysis is also part of my activities to assist in the compliance of systems or documents with specific cybersecurity standards (UL-2900, FDA approval, RGS***, Restricted Dissemination, ISO-27x, etc.).

Finally, I am also an educational instructor in offensive cybersecurity (Internal or school).

In my personal time, I am a cybersecurity researcher and hunter on bug bounty platforms, mainly YesWeHack and Bugcrowd (primarily on private programs).

Coming from a software development background as a Technical Leader in an Agile Scrum environment and holding an engineering degree specializing in Software Engineering, I would also be happy to provide any expert advice on developing software solutions.
