How to locate a hidden firewall?

I received a large bill from an Azure Firewall recently. I am confused because while this has happened before, I deleted the firewall last time to ensure it doesn't happen again, and yet I have an even larger bill. I have tried to look for this "Azure Firewall Standard" everywhere through the portal and yet I cannot find it. Any ideas how I can locate it so I can find and delete it for good? Maybe I'm missing something else?

    To locate a hidden Azure Firewall that may be incurring costs, you can use the Azure portal, Azure CLI, or Azure PowerShell to validate your resources. Here are steps you can follow:

    1. Azure Portal: Log in to the Azure portal and navigate to the Resource Groups section. Check each resource group for any existing Azure Firewall resources.
    2. Azure CLI: You can use the following command to list all resources in a specific resource group: 
         az resource list --resource-group <YourResourceGroupName>
      Replace <YourResourceGroupName> with the name of your resource group.
    3. Azure PowerShell: Similarly, you can use PowerShell to get a list of resources: 
         Get-AzResource -ResourceGroupName <YourResourceGroupName>
      Again, replace <YourResourceGroupName> with the appropriate name.

    If you still cannot find the firewall, consider checking for any associated public IP addresses or other resources that might be linked to the firewall, as they could also contribute to the billing.

    Additionally, ensure that you check all subscriptions you have access to, as the firewall might be deployed in a different subscription than the one you are currently viewing.

    Hi Luke,

    One thing you can do is navigate to your subscription in the portal, on left click on Cost Management -- Cost analysis. Next, at the top, click on View -- CostByResource.

    Once it displays list of resources, scroll down until you see your Azure Firewall and click on link for it in Resource column. This should take you to the Azure Firewall so that you can delete it if necessary.

    Additionally, if things are working properly below link should show you list of firewalls in your subscription:

    https://portal.azure.com/#view/Microsoft_Azure_HybridNetworking/FirewallManagerMenuBlade/~/azureFirewallsMenuItem

    Sometimes even after deleting a resource the billing for it gets "stuck". In these cases you need to create billing support request and have billing engineer investigate. You should gather activity logs showing proof that you deleted it.

    Once they investigate and get rid of the phantom billing they will issue refund/waiver of charges. If you believe this is the case I can post instructions for creating billing support request.

    Hi @ Luke Young,

    Welcome to Microsoft Q&A Platform.

    I can see you're having trouble locating your Azure Firewall, especially after receiving a large bill.

    1. Check the Azure Portal:
      • Start by logging into the Azure Portal. with the correct subscription where the firewall is created.
      • Navigate to "All resources" and filter by resource type for "Firewall" to see if it shows up there.
    2. Resource Groups:
      • Sometimes resources can be grouped together. Make sure to check the resource groups where you typically deploy services, as the firewall may be under one of those.
    3. Resource Manager:
      • Use the resource manager or Azure CLI to list all your firewalls across subscriptions if you have multiple. The command you can run is: 
             az network firewall list --resource-group <your-resource-group-name>
    4. list all resources in a specific resource group with in the subscriptions.
    az resource list --resource-group <YourResourceGroupName>
    1. Costs Management:

    In the Azure portal, go to Cost Management + Billing, select the correct subscription, open Cost analysis, and set View by to Cost by resource.

    6. Deleting the Firewall:

    • Once you locate it, you can delete the firewall from the resources list. Ensure to check if you have any dependencies or associated resources before deletion.
