What I'm looking for

I'm looking for a security operations or incident response role where I can investigate alerts, hunt threats, improve vulnerability and identity controls, and contribute to a global follow-the-sun SOC.

At Tata Technologies, I investigate 15–30 security alerts per shift using Microsoft Sentinel and Defender XDR, validating IOCs and escalating confirmed incidents in line with MITRE ATT&CK and SOC SLAs.

I’ve investigated phishing campaigns, coordinated mailbox remediation, and supported threat hunting, malware analysis, and end-to-end vulnerability management with Qualys VM, Tenable Nessus, Rapid7 InsightVM, and OpenVAS.

Across Tata Technologies, TTEC Digital, and HCLTech, I’ve supported global Microsoft environments, identity governance, VPN access, and enterprise incident resolution. I bring 3+ years in security monitoring and incident response alongside 7+ years in enterprise IT.
