At Cisco Systems, I monitor and investigate more than 12,000 daily security events using Microsoft Sentinel, Splunk Enterprise Security, and Microsoft Defender XDR. I improve detection accuracy, reduce false positives, and accelerate containment for phishing, malware, credential compromise, and unauthorized-access incidents.

I perform threat hunting across Windows, Linux, Azure, and hybrid cloud environments using KQL, Splunk SPL, and PowerShell. I also automate SOC workflows for log collection, phishing investigations, incident ticketing, and security reporting.

Previously at Cognizant, I investigated enterprise security alerts, managed endpoint protections, assessed vulnerabilities, and supported IAM activities across client environments. My work included Splunk, IBM QRadar, Microsoft Defender, CrowdStrike Falcon, Tenable Nessus, Qualys VMDR, Active Directory, and Azure AD.

I partner with infrastructure, cloud, application, and compliance teams to strengthen security posture and support NIST, ISO 27001, CIS Controls, HIPAA, PCI-DSS, and SOC 2 requirements.
