Hi, I’m Ralf, a 49-year-old IT Administrator from Bavaria. With over 20 years of hands-on experience in the Microsoft ecosystem, I specialize in Active Directory (including all services), Exchange on-premises and online, Entra ID, Intune, and IT Security – with a strong emphasis on Ethical Hacking.
As Security Office in my company, I’m the go-to expert for implementing security guidelines, educating teams on safe AI use (like Copilot or Claude), and tackling real-world threats through practical configs and PowerShell automation.
My Blog Focus
This blog shares battle-tested solutions for IT pros: from AD hardening and PKI management to Entra protection and Intune best practices. Expect scripts, configs, and tips straight from production environments – no fluff, just actionable IT-Security insights themed around Microsoft infrastructure.
Beyond the Datacenter
Outside work, I train in Krav Maga (focusing on self-defense), enjoy reading, playing chess, and stargazing as an amateur astronomer.
