- Defender for Endpoint license assigned to the end-user. See Microsoft Defender for Endpoint licensing requirements.
- iOS device enrolled via the Intune Company Portal app
- Device registered with Azure Active Directory
- iOS 12 and above required
- MEM Requirements for IOS onboarding (MDM push certificate)
Integration with Microsoft Endpoint Manager
Defender for Endpoint makes it possible to integrate with Microsoft Endpoint Manager. With the integration, it is possible to share risk-level information and use it with compliance policies. The connection with Microsoft Endpoint Manager can be enabled in the Microsoft Defender Security Center portal.
- Open Microsoft Defender Security Center
- Navigate to Settings -> Advanced features
- Configure Microsoft Intune Connection.
Now we need to allow iOS devices in the Microsoft Endpoint Manager admin center. To enable the feature for IOS, follow the following steps:
- Open Endpoint Manager admin center
- Navigate to Endpoint Security -> Microsoft Defender for Endpoint
- Now configure the: Connect iOS devices to Microsoft Defender for Endpoint to On
With this feature, the compliance policy integrates with Microsoft Defender for Endpoint and can be used for blocking access to corporate data in case of threats/ risk levels.
Deployment of the Microsoft Defender for Endpoint iOS app
The Defender for Endpoint app can be deployed by using Microsoft Intune. For using zero-touch deployments it is recommended to use and integrate the deployment with MEM to silently onboard and configure the app.
- Open Endpoint Manager admin center and navigate to the apps panel.
- Now click on iOS/iPadOS
- Click Add and select the iOS Store app as App type
- Search for the app Microsoft Defender for Endpoint, select the app and click next
- Fill in the additional information if needed for the deployment profile.
- In the Assignments section, go to the Required section and select Add group. Important: The user group must be based on users and not devices.
Configuring zero-touch onboarding
The next step is configuring the iOS configuration profile for the zero-touch onboarding. With zero-touch onboarding, admins can configure the onboarding and configuration completely silent without any user interaction.
For creating the configuration profile:
- Open Endpoint Manager admin center
- Navigate to Devices -> Configuration Profiles -> Create profile
- Select the platform iOS/ iPadOS and the profile type VPN
- Fill in the custom configuration profile name
- In the configuration settings panel, it is required to configure the connection type. For Defender for Endpoint we will configure the Custom VPN connection type.
- Now it is time to configure the Base VPN and Automatic VPN configuration. For configuring the correct profile use the below settings:
Base VPN settings:
- Connection Name = Microsoft Defender for Endpoint
- VPN server address = 127.0.0.1
- Auth method = “Username and password”
- Split Tunneling = Disable
- VPN identifier = com.microsoft.scmx
- Key-Value: SilentOnboard with value to True
With the result:
Automatic VPN settings:
- Type of Automatic VPN = On-demand VPN
- On-demand rules: I want to restrict to Establish VPN for all domains
With the result:
The configuration profile can be deployed to one of the available user groups. Important to scope the profile directly to the user group and not device-based.
Once the app and the configuration item are deployed the following actions will take place on the iOS devices after a successful MEM enrollment. Note: MEM onboarding is not part of this blog.
- User registered devices and installs company portal
- Devices sync apps and configurations
- Microsoft Defender for Endpoint will be silently installed and configured
- Web protection and other features will be silently configured for Defender for Endpoint
- Device onboarded into Defender for Endpoint portal
With the configuration profile and app deployed there is no need for the user to open directly the app for completing the onboarding. After some time the device is visible in the Defender for Endpoint console.
The experience is without any manual action. Directly after installing the following screen is visible in Defender for Endpoint. VPN profile is configured automatically – no user interaction is needed for completing the configuration.
