Message

At HCL TECHNOLOGIES PVT LIMITED, I deploy and administer IT and OT SIEM implementations, upgrades, and integrations. I develop parsers and detection rules, and support OT asset monitoring and secure remote access.

I also perform OT/ICS vulnerability assessments and penetration testing, including asset discovery, CVE/CVSS analysis, risk prioritization, and authorized testing. I handle P1 security incidents, contributing troubleshooting, root-cause analysis, stakeholder coordination, and resolution.

At NETCON TECHNOLOGIES PVT LIMITED, I built and secured two data centers from scratch, covering IT and OT cybersecurity deployment. I implemented SIEM and SOAR, integrated logs, developed detection rules, and supported security monitoring.

Earlier, at VOLTECH IT SOLUTIONS, I managed OT/ICS vulnerability assessments and security remediation, including across 1,200+ live websites. My work has also included monitoring and maintaining industrial control systems, supporting PLC, HMI, and SCADA environments, and troubleshooting industrial networks.
