Carlos Suarez
Security Solution Engineer at Microsoft, focused on identity, AI agent security, and the Microsoft security stack (Entra, Defender).
Contosec is where I write up what I learn from customer conversations. The questions that keep coming back, the patterns I see across deployments, and the parts of Microsoft's security stack that need a practitioner's translation, not just product documentation.
The site is intentionally small. Articles are deep, interactive when it helps, and updated when the underlying product evolves. Projects are open-source tools I've built or co-built to fill specific gaps for Microsoft enterprise customers.
If you work in Microsoft identity, AI security, or the broader Microsoft 365 security ecosystem, the writing here aims to save you the time I spent figuring it out the first time.
