My name is Ivan Krpelnik and I work as a Cloud Security Architect focused on Microsoft cloud technologies, enterprise security architecture, and modern identity and endpoint protection. My work revolves around designing secure environments built on Microsoft 365, Microsoft Entra, Microsoft Defender, and Microsoft Sentinel. I spend most of my time operating at the intersection of security architecture, security operations, and real world enterprise infrastructure.

Over the years I have worked across multiple areas of IT including systems administration, endpoint management, identity architecture, and security operations. Today my primary focus is on building and operating security platforms that protect thousands of users and devices in global enterprise environments.

This blog exists as a place to document practical knowledge from the field. I write about cloud security architecture, Microsoft security technologies, identity and access management, endpoint security, threat detection, and the operational realities of running a modern Security Operations Center.
