Microsoft Security Certs CompTIA Security+ eJPT AD / Entra / GPO

I work in cybersecurity in Central Europe, primarily hardening Microsoft environments — Active Directory, Entra ID, Group Policy, endpoints. The stuff that actually gets attacked.

I started where most of us start: help desk. Moved into sysadmin work, managed AD, endpoints, email, backups — the full stack with no dedicated security team and no budget. After several years of that, I moved into security engineering full-time because I kept finding the same gaps in every environment I touched.

The certifications help. The real knowledge comes from years of staring at event logs, building GPOs that don't break things, and learning which registry keys actually matter at 11pm on a Friday.

I started The Hardening Brief because I wanted a resource I wish I had when I was a sysadmin — one hardening fix per week, copy-paste ready, no fluff, no sales pitch. Just the GPO path, the PowerShell command, and why it matters. Free.

If any of that sounds useful, the newsletter lands every Wednesday morning.
