About me

Meet
Prasanth.

I'm a Network Security Engineer at NTT India Private Limited, currently working on NAC L1 Support at Indian Bank HQ under Managed Services. With a strong foundation in Azure cloud security and infrastructure, I bring hands-on experience in network access control, endpoint compliance, and enterprise security operations.

I hold a Post Graduate Diploma in Cloud Data Management from Conestoga College, Canada, and have built two enterprise Azure projects covering secure networking, NSG hardening, KQL monitoring, RBAC governance, and CI/CD automation — skills that directly complement my work in network security and infrastructure.

Common questions about my background, current role, and how to get in touch.

I am a Network Security Engineer (NAC L1 Support) at NTT India Private Limited, deployed at Indian Bank HQ under Managed Services. I monitor and maintain network security infrastructure using ForeScout NAC and Cisco ISE.
Microsoft Certified: Azure Fundamentals (AZ-900) and AWS Certified Cloud Practitioner (AWS CCP). Currently targeting AZ-104 as the next milestone.
CloudGuard is my enterprise-grade Azure project covering 6 phases: secure networking, NSG hardening, Log Analytics monitoring with KQL, automated alerting, custom RBAC governance, Azure Policy, and Microsoft Defender for Cloud.
CloudGuard IaC Pipeline is my second Azure project — it automates the entire infrastructure deployment using Terraform and GitHub Actions CI/CD. Every push to GitHub triggers an automated pipeline that provisions Azure VNet, subnets, and NSG — eliminating manual portal clicks.
ForeScout NAC, Cisco ISE (AAA), 802.1x/MAB authentication, RADIUS, Active Directory, Cisco/Aruba/Tejas switches, WAF, SSLO, and ITSM ticketing. On the cloud side: Azure, Terraform, GitHub Actions, KQL, and Microsoft Defender for Cloud.
