Vijay Kumar Seelam

I’m an IT security professional with 4+ years of experience, including 3+ years in a Security Operations Center (SOC). I focus on threat detection, incident response, and threat hunting—using strong SIEM monitoring, alert triage, IOC analysis, and log investigation to quickly identify and mitigate real risks.

At TATA CONSULTANCY SERVICES, I deliver 24/7 SOC monitoring using SIEM and EDR to detect threats aligned with MITRE ATT&CK. I improved SIEM correlation rules and detection logic, reducing false positives by 30% and accelerating investigation efficiency across security monitoring workflows.

I mitigate threats through proactive hunting across endpoint, authentication, IDS, and network telemetry—investigating Windows endpoint incidents, persistence artifacts, and authentication anomalies to identify attacker techniques and compromised systems. I also perform incident response containment and remediation (host isolation, IOC blocking, credential resets, and system remediation), reducing MTTR by 25%, and strengthen identity security by investigating Microsoft Entra ID Identity Protection alerts to address account takeover risks.

Beyond core SOC operations, I analyze phishing using Abnormal Security and Mimecast with header analysis, URL validation, and sandbox testing—reducing endpoint compromises by 40%. I complement this with external attack surface risk monitoring using Digital Shadows Searchlight and operational discipline through incident reports and SOC playbooks; earlier, as a Software Developer, I bring a careful, test-driven approach to improving detection and response workflows.
