In this video, we dive into Azure’s new Private Subnets virtual network feature, which brings greater security and control to your Azure VMs. Starting in September 2025, Microsoft will disable default internet access for Azure VMs, impacting organizations relying on direct outbound internet connections. Please join me as we walk through how Private Subnets enable explicit internet configuration, reducing security risks by ensuring VMs don’t bypass organizational firewalls and content filters without authorization.

Follow along as we create a private subnet on an Azure VNet in the Azure Portal, move a VM into it, and test internet connectivity to see firsthand how the feature restricts access without a defined NAT gateway or other route. Perfect for Azure admins and cloud architects, this tutorial ensures you’re prepared for upcoming changes and better VM security in Azure.
