Back to original languageAbout Kilian
Freelance since 2021, I support companies during incident response. My approach combines high-level technical expertise and transmission skills.
My pillars of intervention:
- Malware Analysis (GREM): Reverse engineering and in-depth study of threats to understand and neutralize attack vectors.
- Digital Forensics (GCFA): Post-incident digital investigation to identify the origin, scope, and impact of a compromise.
- SOC Expertise: Optimization of detection and support for operational teams.
- Pedagogy: Also a trainer, I pass on my know-how on these subjects to build your teams' skills.
