Summary
👤
Senior🎓
Top SchoolArun Jothimani is a cloud security engineer and architect with 10 years of experience designing scalable, policy-driven security platforms for large enterprises. He has led cloud security and governance across thousands of Azure subscriptions, architecting Terraform-based policy engines, CIEM-informed IAM frameworks, and integrated CSPM/CNAPP solutions that materially reduced misconfigurations and privileged access risk. At H&M and Zenseact he combined DevSecOps, telemetry, and automation to cut MTTR, modernize legacy observability, and embed security into developer workflows rather than bolt it on. Now at Microsoft, he focuses on real-time posture management using Defender for Cloud, Azure Policy, and Sentinel while helping organizations shift from reactive ops to automated guardrails. He’s equally comfortable in hands-on platform engineering and strategic vendor evaluation, having benchmarked Wiz, Prisma, and Microsoft Defender for Cloud to guide tool selection. Outside of work he brings a pragmatic researcher’s mindset from his Chalmers master’s thesis on Policy-as-Code, turning academic ideas into production governance.
