I've supported security operations at Wipro, Diageo, Cognizant, IBM, HCL Comnet, and Sysco Infotech, investigating incidents across financial, banking, and enterprise environments.

At Wipro and Diageo, I analyze phishing, account compromise, host activity, gateway sign-ins, data breaches, and third-party incidents. I use Microsoft Defender, VMRay, VirusTotal, sandboxing, Rapid7 Threat Command, and EDR/XDR tools to identify IOCs, persistence techniques, and external threats; I also block malicious domains, URLs, hashes, and IPs while maintaining 95–98% ticket resolution within SLA timeframes.

My background also includes SOC monitoring with QRadar, ArcSight, LogRhythm, Kibana, Symantec, Carbon Black, Nessus, and Cyberoam, along with endpoint security, Active Directory, BMC Remedy, VPN, and user support.
