What I'm looking for

I’m looking for a lead position in the Cybersecurity domain where I can drive zero-trust micro segmentation, mentor teams, and strengthen endpoint and network security operations across cloud and on-premise environments.

I’m an experienced cybersecurity expert with 2 decades in systems and network domains, with a strong focus on endpoint and network security operations. I’ve led a project on design and implementation of zero trust micro segmentation using Illumio, aligning security controls across cloud and on-premise environments.

In my current role as Technical Lead, Cyber Security at Wipro Technologies Ltd, I manage Illumio PCE/VEN and build segmentation policies for enterprise networks. I also train and mentor application teams to adopt micro segmentation using in-house self-service tools, and support security measurement and reporting to help monitor effectiveness.

Previously at Morgan Stanley through Russell Tobin India Pvt Ltd, I planned and provided enterprise Level 3 support for platform security operations and endpoint security tools across Linux and Microsoft Windows. Earlier, as a Sr. Lead/Lead Engineer and Systems Engineer, I delivered end-to-end Windows Server support, Active Directory migrations, virtualization and Citrix administration, patching and release processes, and security operations that met audit/compliance needs.
