What is a secured virtual hub?

  • Artikkeli

A virtual hub is a Microsoft-managed virtual network that enables connectivity from other resources. When a virtual hub is created from a Virtual WAN in the Azure portal, a virtual hub VNet and gateways (optional) are created as its components.

A secured virtual hub is an Azure Virtual WAN Hub with associated security and routing policies configured by Azure Firewall Manager. Use secured virtual hubs to easily create hub-and-spoke and transitive architectures with native security services for traffic governance and protection. Multiple secured hubs can be deployed within the same region or across regions part of the same Virtual WAN resource. Use Firewall Manager in the Azure Portal to add additional secured hubs.

You can use a secured virtual hub to filter traffic between virtual networks (V2V), branch-to-branch (B2B)*, branch offices (B2V) and traffic to the Internet (B2I/V2I). A secured virtual hub provides automated routing. There's no need to configure your own UDRs (user defined routes) to route traffic through your firewall.

You can choose the required security providers to protect and govern your network traffic, including Azure Firewall, third-party security as a service (SECaaS) providers, or both. To learn more, see What is Azure Firewall Manager?.

Create a secured virtual hub

Using Firewall Manager in the Azure portal, you can either create a new secured virtual hub, or convert an existing virtual hub that you previously created using Azure Virtual WAN.

*Virtual WAN routing intent must be configured to secure inter-hub and branch-to-branch communications, even within a single Virtual WAN hub. For more information on routing intent, see the Routing Intent documentation.
