Azure Security Center scans your Azure resources and provides recommendations to secure workloads
that need a next-generation firewall. The recommendation displays on the
dashboard and you can then either deploy a new instance of the VM-Series
firewall from the Azure marketplace or you can use the Azure CLI, PowerShell, or
an ARM template. The advantage of using a customized deployment using Azure CLI,
PowerShell, or ARM template is that you can deploy the VM-Series firewall within
the same resource group as the workload that you need to secure. When you deploy
the VM-Series firewall using the Azure marketplace, Azure requires that you
deploy the firewall into a new resource group or an empty resource group only.
Therefore, the marketplace deployment requires you to then ensure that the
traffic from the workload you want to secure is steered to the firewall that is
in a different resource group.
