I started out as an all-round ‘generalist’ where I’ve gained many years of experience working for small businesses configuring, migrating and troubleshooting Windows environments, private-cloud infrastructure and everything that comes with it like networking, storage and hypervisors. But since the end of 2017 my focus has shifted primarily towards Microsoft Azure and specifically Azure Security and other Microsoft Security products like Microsoft Sentinel and Defender XDR. Besides helping with architectural design choices, I find it important to be able to build the solutions myself as well. So, I’m no stranger to ARM templates, PowerShell, Git and Azure DevOps Pipelines. Lately, I’ve been focusing mainly on implementing Microsoft Sentinel and improving Security Operations Centers by helping with the development of new detections, ingesting log sources, and applying processes for automatic enrichments and investigations. KQL and Azure Logic Apps have become two of my new best friends! I like to share the challenges I encounter and my solutions in my articles on Medium [ https://aka.ms/koos] and in session at events. This led to Microsoft awarding me MVP in 2023 for both the technology areas Cloud Security and SIEM & XDR. #Microsoft #Security #MVP #Azure #Sentinel #Defender #DevOps #ARM #KQL #PowerShell #Logstash
