About me
Hi, I’m Dimosthenis — a Senior Cloud Architect specialising in Microsoft 365 and Microsoft Security Copilot.
I work day-to-day with the Microsoft cloud security stack — Defender XDR, Sentinel, Entra ID, Intune, Purview, and the rapidly evolving Security Copilot platform — and I write here to share what works in the real world, what doesn’t, and what’s worth your attention as a practitioner.
This blog is practical, hands-on, and opinionated. It’s not a copy of Microsoft Learn. The goal is to fill the gap between official documentation and what you actually face in production.
What you’ll find here
- Microsoft Security Copilot — prompts, plugins, integration patterns, cost optimisation, and security guardrails.
- Microsoft 365 hardening — Conditional Access, attack-surface reduction, Defender configuration, baseline architectures.
- Identity & access — Entra ID, hybrid identity, Kerberos trust, privileged access, and zero-trust building blocks.
- Detection & response — KQL hunting queries, custom analytics, automation with Logic Apps, incident playbooks.
- Architecture deep dives — multi-tenant patterns, cross-cloud integrations, and design decisions for regulated industries.
