About

I design and operate security architectures centered around the Microsoft Security Stack — Defender XDR, Microsoft Sentinel, Entra ID, and Intune. My work spans threat detection, identity governance, and endpoint security across complex enterprise environments.

Detection Engineering is a core focus: I build KQL-based detection rules, map them to MITRE ATT&CK, and maintain them in multi-tenant Microsoft Sentinel deployments.

Based in Saarland, working fully remote. Engagements primarily in German-speaking DACH organizations, delivered in German or English.

Writing

Regular posts on LinkedIn — Security Architecture, Detection Engineering, SecOps. Practical content for practitioners, not slideware.
