Thomas Alexander Lysaa
A Principal Security Advisor with extensive expertise in navigating the complexities of the Microsoft ecosystem. My focus is on architecting secure, resilient infrastructures that bridge the gap between technical defense and strategic cloud governance.
I specialize in the end-to-end implementation of Microsoft Sentinel, Defender, and Microsoft Entra. My depth of experience encompasses KQL-driven automation, Azure Security optimization, and managing risk across identity, endpoint, and data protection through Microsoft Purview and Intune. I lead architectural transformations that prioritize compliance and proactive defense.
