What I'm looking for

I'm seeking a Senior SOC Analyst or Incident Response role focused on threat detection, investigation, and response.

At Atos Global IT Solutions, I monitor and investigate security events using AIsaac, Atos’ AI-based MDR platform. I also tune SIEM rules, whitelist alerts, and automate SOAR workflows to improve incident response efficiency and reduce false positives.

As a Junior Associate at Atos Global IT Solutions, I monitored IBM QRadar offenses and investigated endpoint, phishing, and identity events using CrowdStrike Falcon, Microsoft 365, and Microsoft Azure. I supported threat hunting by identifying suspicious patterns and IOCs, and used Google SecOps SOAR (Siemplify) for incident response and containment actions.

As a Cybersecurity Intern at PurpleSynapz, I gained hands-on experience through cybersecurity labs in networking, Windows security, cloud security, SIEM, VAPT, and digital forensics. I also used tools including AlienVault, OpenVAS, Check Point Firewall, Nmap, Nessus, Burp Suite, and Wireshark.
