In this article, I will share with you how to check Azure Defender status (formerly known as the Standard Tier in Azure Security Center) on every Azure subscription with PowerShell.

Introduction

Azure Security Center gives you complete visibility and control over the security of hybrid cloud workloads, including compute, network, storage, identity, and application workloads. Azure Security Center (ASC) has two mains value proposition:

1. Cloud Security Posture Management (CSPM) – Help you prevent misconfiguration to strengthen your security posture for all different types of cloud workloads and resources in Azure (IaaS, PaaS, and SaaS). CSPM in Security Center is available for free to all Azure users.
2. Cloud Workload Protection Platform (CWPP) – Protect against threats for servers whether they are running in Azure, on-premises, or different clouds such as Amazon AWS or Google GCP, in addition to cloud-native workloads such as Web Apps, Kubernetes, Key Vaults, as well as for SQL databases (PaaS/VM) and storage accounts. CWPP is part of the Azure Defender plan (formerly known as the Standard Tier).

Azure Defender is an evolution of the threat-protection technologies in Azure Security Center, protecting Azure and hybrid environments. When you enable Azure Defender from the Pricing and settings area of Azure Security Center, the following Defender plans are all enabled simultaneously and provide comprehensive defenses for the compute, data, and service layers of your environment:

• Azure Defender for servers
• Azure Defender for App Service
• Azure Defender for Storage
• Azure Defender for SQL
• Azure Defender for Kubernetes
• Azure Defender for container registries
• Azure Defender for Key Vault
• Azure Defender for Azure DNS
• Azure Defender for Resource Manager

From the Pricing and settings area, you can also enable or disable one of the Azure Defender plans as shown in the figure below.

What if you have many subscriptions and you want to know which Azure Defender plan is enabled on which subscription?

In this quick article, I will share with you how to query Azure Defender on every Azure subscription and get its status with PowerShell.

Prerequisites

To follow this article, you need to have the following:

1. Azure subscription – If you don’t have an Azure subscription, you can create a free one here.
2. Azure Security Center Free or Azure Defender enabled.
3. Azure PowerShell installed locally on your machine or using Azure Cloud Shell.
4. The Azure Resource Graph module for PowerShell. Please note that this module can be used with locally installed PowerShell, with Azure Cloud Shell, or with the PowerShell Docker image.

Install the module

In this example, I am using the Azure Cloud Shell. Open the Cloud Shell and run the following commands to install the Azure Resource Graph module from PowerShell Gallery.

# Install the Resource Graph module from PowerShell Gallery
Install-Module -Name Az.ResourceGraph
# Get a list of commands for the imported Az.ResourceGraph module
Get-Command -Module 'Az.ResourceGraph' -CommandType 'Cmdlet'

At the time of this writing, I am running the latest Resource Graph PowerShell version (0.7.7).

Get Azure Defender status

Assuming you have all the prerequisites in place, open the Azure Cloud Shell (https://shell.azure.com/) and run the following command:

# Query Azure Defender Status and sort by tier
Search-AZGraph -Query "securityresources | where type == `"microsoft.security/pricings`" | extend tier = properties.pricingTier | project name, tier, subscriptionId" | Sort-object tier

In my example, the output looks like this. You can see the name of each Azure Defender plan if it’s enabled (Standard), or not (Free). The Standard tier is still referred to the old naming, I believe that Microsoft will change it to Azure Defender in the future (the subscription Id has been intentionally obscured in this example).

That’s it there you have it!
