About

Hi, I'm Rudnei // Microsoft Cybersecurity Solution Engineer

I work as a Microsoft Cybersecurity Solution Engineer, helping customers design and operationalize security across the Microsoft stack — Azure Security, Microsoft Sentinel, Defender for Cloud, Defender XDR, Entra ID security, and Microsoft Purview (MIP, DLP, Insider Risk Management). This site is my open notebook: mind maps, deep-dive references, and operational notes I've found useful and want to share.
