What I'm looking for

I'm looking to contribute my SOC operations, incident response, SIEM, and threat-defense skills within an innovative, vibrant organization that supports continuous improvement in cybersecurity.

At Tata Communications, I monitor and investigate security events in LogRhythm, tune correlation rules, integrate log sources, and improve threat detection accuracy. I support incident response through malware analysis, phishing investigations, containment actions, MITRE ATT&CK mapping, and IOC-based investigations.

I've spent 8 years in cybersecurity SOC operations across Tata Communications, LTIMindtree, and BR SQR IT Solutions. My work spans ArcSight, QRadar, Securonix, LogRhythm, Cortex SOAR, SentinelOne, FireEye, threat hunting, incident reporting, and security-device log troubleshooting.
