India

Message

At BMC Software, I lead Cyber Threat Management initiatives spanning threat actor profiling, APT analysis, and intelligence-led cyber defense. I conduct hypothesis-driven threat hunting using MITRE ATT&CK and adversary TTPs and IOAs.

I develop detection engineering capabilities, including custom detection and correlation rules, and automate CTI ingestion, enrichment, and IOC correlation to support detection and response.

At TIAA GBS, I led CTI and threat hunting operations and developed Executive Protection Intelligence programs. I also delivered threat intelligence reports and executive threat assessments to support risk-based decision-making.

At IBM, I led DFIR operations for high-severity incidents and conducted threat hunting, vulnerability assessments, and breach and attack simulations. I hold a B.Tech in Information Technology and certifications in cybersecurity, penetration testing, information security, and the Picus platform.
