About Miriane

• Endpoint investigation with CrowdStrike Falcon: containment and remediation of confirmed incidents
• Full incident response: containment, coordination, report writing
• Optimization of SOC detection rules and playbooks
• Automation via Ansible and Python (SOAR logic)
• Threat Intelligence (MITRE ATT&CK, OpenCTI) and alert enrichment
• SI mapping, vulnerability scans (Nessus, Nmap) and EBIOS RM risk analysis
• Cybersecurity best practice awareness

Environments: Azure, Windows Server, Linux, Active Directory, Docker, VMware.

Available for SOC monitoring, incident response, vulnerability analysis, or security audit missions.
