Message

At JINDAL POWER, I implement ISO/IEC 27001:2022 controls across thermal power plant ICS/OT infrastructure. I monitor OT threats with Claroty CTD and manage vulnerability and patch management on OEM-tested platforms.

At APRAAVA ENERGY, I managed cybersecurity for DCS, PLC, OT servers, workstations, and network infrastructure. I handled vulnerability assessments and supported secure architecture, network segmentation, and firewall controls.

Earlier at APRAAVA ENERGY, I implemented OT access controls and Active Directory/GPO security, and managed DCS/PLC and server backup and restoration activities. I also supported ICS security hardening and secure configuration, and troubleshot Matrikon OPC communications.

I began my career at APRAAVA ENERGY working with ICS systems, including DCS and PLCs, and later reviewed control-system drawings and documents and calibrated actuators. My training includes Claroty certifications, cybersecurity for power professionals, and ISO/IEC 27001:2022 implementation experience.
