As a seasoned Information Security Lead with over 13 years of experience, I specialize in safeguarding complex infrastructures through advanced Security Operations (SOC), Vulnerability Management, Risk Management and proactive threat monitoring. I have successfully played a key role in building, transforming, and optimizing SOC capabilities for large organizations across multiple geographies. My expertise includes designing SOC operating models, defining processes and KPIs, implementing SIEM, Endpoint Security and other platforms, and leading end-to-end SOC transformations. My expertise spans a wide range of cutting-edge security tools and technologies, including QRadar, Splunk Enterprise, Google SecOPs, Rapid7, MDE, Crowdstrike, McAfee ePO and Zscaler enabling me to design and implement comprehensive cybersecurity strategies that align with business objectives. I am also skilled in conducting security gap assessments and root cause analyses, providing actionable recommendations to mitigate operational and strategic risks.

In my current role at Tata Consultancy Services, I collaborate with cross-functional teams to remediate vulnerabilities, drive security improvement initiatives, and manage end-to-end SOC. With a strong focus on continuous learning and innovation, I remain committed to staying ahead of evolving cyber threats to protect organizations and their critical data.

I am passionate about building resilient cybersecurity systems, enhancing threat detection capabilities, and ensuring regulatory compliance and framework. My current role has involved frequent interaction with C-level stakeholders as well, where I’ve developed the ability to tailor my communication—clearly translating technical risks into business impact for executives, while engaging in deep technical discussions with engineering/security teams.
