At Tata Consultancy Services, I monitor, triage, and investigate security alerts across Microsoft Sentinel, Splunk, CrowdStrike Falcon, and Microsoft Defender for Endpoint in a 24x7 SOC environment.

I've built and tuned KQL and SPL detection rules, CrowdStrike Falcon and Defender prevention policies, and Sentinel Logic Apps and playbooks to reduce false positives and streamline response. I investigate malware, phishing, brute-force, impossible travel, and account-compromise incidents through containment, remediation, RCA, and incident reporting.

I also conduct proactive threat hunting and digital forensics using endpoint artifacts, Windows Event Logs, registry analysis, process trees, command-line activity, and network evidence. My work includes Proofpoint email security, vulnerability prioritization with Tenable Nessus and Qualys, and detection use cases mapped to MITRE ATT&CK and NIST.

Before moving into SOC operations, I supported software quality at Tata Consultancy Services through test planning, test execution, defect reporting, and regression testing.
