What is Defender for Cloud / Defender for Servers

Microsoft Defender for Cloud/ Defender for Servers is the way for onboarding Windows Servers in Defender for Endpoint. With Microsoft Defender for Servers (part of Defender for Cloud), you automatically deploy Microsoft Defender for Endpoint Plan 2 to server resources using the integration. The license is part of Defender for Servers.

Defender for Cloud contains two plans which enable Defender for Endpoint Plan 2. In Defender for Cloud there is a Defender for Servers Plan 1 and Plan 2 available. Plan 2 enables more benefits and additional enhanced security features.

Comparison table between Defender for Servers P1/ P2 offering: For 10$ extra in cost there are more features part of Defender for Servers that can be used for increasing the security posture. Defender for Servers Plan 1 is good when using only the Defender for Endpoint / Vulnerability management and agent onboarding. There is no difference in Defender for Endpoint, both P1 and P2 enable the Defender for Endpoint Plan 2 product.

When using Defender for Servers P2, it includes the Defender Vulnerability Management add-on capabilities part of the Defender for Servers P2 capabilities. No extra license is required.

How works the flow

Microsoft Defender for Endpoint integrates seamlessly with Microsoft Defender for Servers. Onboarding is automatic with the extension provisioning.

The following integrations are enabled using Defender for Endpoint with Defender for Cloud:

  • Automated onboarding: Defender automatically enables the Defender for Endpoint sensor using the new unified agent for all supported system
  • Single pane of glass: The Defender for Cloud portal pages display Defender for Endpoint alerts. Where you can drill down into Defender for Endpoint portal for more in-depth alert information


When enabling Defender for Servers Plan 1 or Plan 2 and configuring the Defender for Endpoint integration – the Defender for Endpoint agent is automatically provisioned on all supported machines in the configured subscription. When enabled all supported machines in the subscription will be onboarded.

When enabled Defender for Cloud/ Defender for Servers deploys the MDE.Windows extension. Part of the MDE.Windows extension installation is the following:

  • Onboard to Defender for Endpoint (MDE)
  • Install Defender for Endpoint unified client for 2012R2/ 2016 (MD4WS.MSI)
  • Uninstall when needed SCEP
  • Install missing patches when needed
  • Trying to update Defender AV product version for 2016 when not updated

Installation flowchart

A basic flowchart explaining the Defender for Servers Plan 1/ Plan 2 integration flow:


Before starting with the integration, we need to confirm a couple of prerequisites for Defender for Endpoint. All MDE prerequisites are explained in part 3 of the series. The following is important when using the integration in combination with Server 2012R2 and Server 2016:

Unified agent

Defender for Cloud/ Defender for Servers installs the new unified agent for Server 2012R2 and Server 2016 via Azure Policy. The new agent requires some new prerequisites which are important for validating the installation of the MDE.Windows extension:


  • Update machines with the latest monthly rollup
  • KB2999226 & KB3080149 are required for 2012R2 (when using the latest monthly rollup, patches are already installed)


  • The Servicing Stack Update (SSU) from September 14, 2021 or later must be installed.
  • The Latest Cumulative Update (LCU) from September 20, 2018 or later must be installed. It’s recommended to use the latest available SSU and LCU and make sure the machines are fully updated before installing Defender
  • Defender Antivirus server role feature must be enabled and running / up to date
  • Update/ install the latest Defender Antivirus platform version (download package from  Microsoft Update Catalog or MMPC)

For more information see: Prerequisites for Server 2012R2 and Windows Server 2016 | Microsoft Docs

Onboard on-premises / non-Azure machines

On-premises/ non-azure machines can be onboarded using Azure Arc or the new Direct onboarding options.

The preferred way of adding non-Azure machines to Microsoft Defender for Cloud is with the use of Azure Arc. When onboarded using Azure Arc the machine becomes an Azure resource and can be easily integrated with Defender for Endpoint. Defender for Servers integration works the same for Azure Arc devices. More information: Connect your non-Azure machines to Microsoft Defender for Cloud

When Azure Arc is not possible the new Direct onboarding solution is possible. With this new method it is possible to onboard servers directly to Defender for Endpoint with the script files and integrate it via Defender for Server for the licensing without additional agents on the server.

View part 3C for more in-depth Azure Arc/ Direct onboarding information. Microsoft Defender for Endpoint series – Onboard using Azure Arc – Part3C 

Enable the integration – Defender for Cloud

In Defender for Cloud it is needed to enable Defender for Servers P1/ P2. Both versions are using the same provisioning. Below explains the manual enablement – PowerShell/ API can be used for enabling the integration for all subscriptions.

For enabling Defender for Servers:

  • Sign in to the Azure portal
  • Search for Microsoft Defender for Cloud
  • In Defender for Cloud, select Environment settings
  • Open the subscription page
  • Enable Defender for Servers Plan 1 or Plan 2

For configuring Plan 1 or Plan 2 use the Change plan button for selecting the relevant plan.

Defender for Servers will be activated for all supported resources in the subscription – when enabled it will onboard Windows and Linux machines to Defender for Endpoint. Linux will be installed with the MDE.Linux extension. NOTE: Linux is onboarded in passive mode.

Enable Defender for Endpoint integration

In the same view for the specific subscription enable the Defender for Endpoint integration. In the section Defender plans open settings & monitoring.

Enable the component Endpoint protection

For new subscriptions, the unified solution and Linux machines integration are enabled and automatically configured.

(1) The button unified solution is only visible for older subscriptions (before June 20th, 2022) where Defender for Servers was already enabled. Advised is to use always the new unified solution which removes the complexity from the legacy MMA solution. When the button is visible; click; Enable unified solution.

(2) The button Linux machines is only visible when the subscription was created earlier than August 2021, with Defender for Servers enabled. Where there is no fix button part of the Endpoint security component all is fine.

Without Defender for Endpoint provisioning?

The following Azure policies can be used for installation without the provisioning in Defender for Cloud.

New available Azure policies:

  • Deploy Microsoft Defender for Endpoint agent on Windows virtual machines
  • Deploy Microsoft Defender for Endpoint agent on Windows Azure Arc machines
  • Deploy Microsoft Defender for Endpoint agent on Linux hybrid machines
  • Deploy Microsoft Defender for Endpoint agent on Linux virtual machines

Auto-provisioning Log Analytics agent / Azure Monitor agent

A common question from organizations; do we need to enable auto-provisioning when using only Defender for Servers/ Defender for Endpoint?

The new MDE solution for 2012R2/ 2016 doesn’t use or require the installation of the Log Analytics agent via auto-provisioning. The Defender solution is based on the SENSE service (compared with Windows 10/ Server 2019 and higher). Auto-provisioning is only needed for the following Defender for Server features. It is always recommended to use more features in Defender for Servers and use the auto-provisioning of the Azure Monitor Agent to use the benefit of all features.

  • Endpoint protection assessment- Security posture management (CSPM)
  • Adaptive application controls – Defender for Servers Plan 2
  • File Integrity Monitoring – Defender for Servers Plan 2
  • Fileless attack detections – Defender for Servers Plan 2

For Defender for Servers Plan 2 the following capabilities require additional monitoring agents. Endpoint protection recommendations check if an endpoint protection solution is installed. OS baseline recommendation checks the OS recommendations part of the system.

Defender AV – installed mode

There is no auto deactivation of Defender if there is another AV for servers active and Defender for Servers is enabled. Only Linux installs automatically in passive mode. When Defender AV is not primary it can be advised to configure Defender AV in passive mode. Important: make sure Defender AV is active when there is no 3rd party AV solution installed. Using the following registry key it is possible to force the passive mode:

  • Path: HKLM\SOFTWARE\Policies\Microsoft\Windows Advanced Threat Protection
  • Name: ForceDefenderPassiveMode
  • Type: REG_DWORD
  • Value: 1

Monitor the installation

The installation of the extension can be monitored via the Azure machine extensions page. The onboarding is completely based on the MDE.Windows extension for Windows Endpoints. Extension installation status can be checked via Extension + Applications in Azure:

Open the specific VM -> open Extensions+applications -> open the MDE.Windows extension for more details

When clicking on the MDE.Windows extension name you will receive more detailed details about the provisioning and status.

When the extension is failed – it is always recommended to check of all prerequisites are correctly configured. Based on my experience the following is common:

  • Defender not running in active mode for 2016/2019
  • Defender server role not installed for Server 2016
  • Correct prerequisites updates not installed
  • Connectivity requirements not correctly configured
  • Defender disabled via a registry key/ GPO setting
