Back to original languageAbout Francois
L3 SOC Analyst and threat hunter — 6 years in cybersecurity, 11 years in IT.
I focus on the most critical part of an SOC: tracking threats that bypass automated tools, qualifying real incidents, and managing the response up to remediation. Proactive threat hunting based on MITRE ATT&CK, SIEM/SOAR deployment and optimization (Microsoft Sentinel, QRadar), reducing false positives and response time.
My background as a systems and network administrator gives me a real understanding of the infrastructure I defend — an asset for quickly understanding an environment and spotting what's wrong. I have worked in various contexts: large corporations, mid-sized companies, environments of 500 to 1,500 users, in France and internationally. Trained in offensive and defensive cybersecurity (Mines de Nancy, BAC+6).
Immediately available, mobile throughout France and open to remote work.
