What I'm looking for

I’m looking for a structured SOC role focused on email security and advanced threat intelligence, where I can improve phishing investigations, SIEM detections, and incident response quality through automation, strong documentation, and collaborative workflows.

I’m a cybersecurity SOC professional with 5+ years of experience in security monitoring, incident response, and network security across government and enterprise environments. I currently serve as a Security IV&V Analyst / Senior SOC Analyst (L4), where I monitor SIEM platforms (Microsoft Sentinel and IBM QRadar), triage alerts, and execute NIST IR lifecycle actions with 90–95% SLA adherence across 24x7 operations.

I strengthen investigations through phishing and email threat handling—analyzing email headers, extracting IOCs, supporting containment, and improving filtering with Defender for Office 365. I also contribute to threat modelling using STRIDE and MITRE ATT&CK, support SOC playbooks and SOPs, and use Python/PowerShell automation to reduce MTTR (30%). Earlier, I delivered web and network penetration testing and validated remediation, and I’m eager to deepen my expertise in email security and advanced threat intelligence within a structured SOC environment.
