Switch to the New Defender for Resource Manager Pricing Plan
Published Dec 05 2023 03:13 PM 2,970 Views


Hi folks! My name is Felipe Binotto, Cloud Solution Architect, based in Australia.


In case you missed it, a new pricing plan has been announced for Microsoft Defender for Resource Manager.


The legacy pricing plan (per-API call) is priced at $4 per 1M API Calls, which can become a bit expensive if there is a lot going on in your subscriptions.




The new pricing plan (per-subscription) is priced at $5 per subscription per month.




We have made available a workbook which provides a cost estimation for all the Defender plans across all your subscriptions.


For more information visit this link.


This new pricing plan is huge for most enterprise customers. This has the potential to reduce your Microsoft Defender for Resource Manager cost dramatically.


However, make sure you make at least 1.25M API calls per month in the subscription you are looking to switch for the new pricing plan. Otherwise, you will end up paying more for the same service.


Switch to the new pricing plan

The easiest way is to switch from the Azure Portal. However, if you have a large number of subscriptions this activity can be super boring!

Currently, there is no native PowerShell cmdlets which can help with the switch, but we can leverage the Microsoft Defender for Cloud REST API.


The script

To make your life easier, I have already developed the script to switch the plan. This script will switch all subscriptions to the new plan. Adapt it to your requirements.





foreach($subId in (Get-AzSubscription | ? State -eq "Enabled").Id){

    $payload = @"
    "properties": {
    "pricingTier": "Standard",
    "subPlan": "PerSubscription"

    $result = (Invoke-AzRestMethod -SubscriptionId $subId -Method Get -ResourceProviderName 'Microsoft.Security' -ApiVersion 2022-03-01 -Name Arm -ResourceType pricings).content | ConvertFrom-Json

    if($ -eq "Free"){

        Write-Host "Subscription $subId is on the Free pricing tier"


        Invoke-AzRestMethod -SubscriptionId $subId -Method Put -ResourceProviderName 'Microsoft.Security' -ApiVersion 2022-03-01 -Name Arm -ResourceType pricings -Payload $payload

        Write-Host "Subscription $subId is on the Standard pricing tier and has been converted to new pricing model"






The new pricing model can provide immediate huge savings and it is very simple to implement. This is one of the easiest ways to save on your Azure spendings.

I hope this was informative for you and thanks for reading.
