Note

Defender for Endpoint on iOS would use a VPN in order to provide the Web Protection feature. This is not a regular VPN and is a local/self-looping VPN that does not take traffic outside the device.

Conditional Access with Defender for Endpoint on iOS

Microsoft Defender for Endpoint on iOS along with Microsoft Intune and Azure Active Directory enables enforcing Device compliance and Conditional Access policies based on device risk score. Defender for Endpoint is a Mobile Threat Defense (MTD) solution that you can deploy to leverage this capability via Intune.

For more information about how to set up Conditional Access with Defender for Endpoint on iOS, see Defender for Endpoint and Intune.

Jailbreak detection by Microsoft Defender for Endpoint

Microsoft Defender for Endpoint has the capability of detecting unmanaged and managed devices that are jailbroken. If a device is detected to be jailbroken, a High-risk alert will be reported to the Microsoft 365 Defender portal and if Conditional Access is setup based on device risk score, then the device will be blocked from accessing corporate data.

Web Protection and VPN

By default, Defender for Endpoint on iOS includes and enables the web protection feature. Web protection helps to secure devices against web threats and protect users from phishing attacks. Defender for Endpoint on iOS uses a VPN in order to provide this protection. Please note this is a local VPN and unlike traditional VPN, network traffic is not sent outside the device.

While enabled by default, there might be some cases that require you to disable VPN. For example, you want to run some apps that do not work when a VPN is configured. In such cases, you can choose to disable VPN from the app on the device by following the steps below:

  1. On your iOS device, open the Settings app, click or tap General and then VPN.
  2. Click or tap the “i” button for Microsoft Defender for Endpoint.
  3. Toggle off Connect On Demand to disable VPN.

    VPN config connect on demand.

 Note

Web Protection will not be available when VPN is disabled. To re-enable Web Protection, open the Microsoft Defender for Endpoint app on the device and click or tap Start VPN.

Co-existence of multiple VPN profiles

Apple iOS does not support multiple device-wide VPNs to be active simultaneously. While multiple VPN profiles can exist on the device, only one VPN can be active at a time.

Configure Microsoft Defender for Endpoint risk signal in app protection policy (MAM)

Microsoft Defender for Endpoint can be configured to send threat signals to be used in App Protection Policies (APP, also known as MAM) on iOS/iPadOS. With this capability, you can use Microsoft Defender for Endpoint to protect access to corporate data from unenrolled devices as well.

Steps to setup app protection policies with Microsoft Defender for Endpoint are as below:

  1. Set up the connection from your Microsoft Endpoint Manager tenant to Microsoft Defender for Endpoint. In Microsoft Endpoint manager admin center, go to Tenant Administration > Connectors and tokens > Microsoft Defender for Endpoint (under Cross platform) or Endpoint Security > Microsoft Defender for Endpoint (under Setup) and turn on the toggles under App Protection Policy Settings for iOS.
  2. Select Save. You should see Connection status is now set to Enabled.
  3. Create app protection policy: After your Microsoft Defender for Endpoint connector setup is complete, navigate to Apps > App protection policies (under Policy) to create a new policy or update an existing one.
  4. Select the platform, Apps, Data protection, Access requirements settings that your organization requires for your policy.
  5. Under Conditional launch > Device conditions, you will find the setting Max allowed device threat level. This will need to be configured to either Low, Medium, High, or Secured. The actions available to you will be Block access or Wipe data. You may see an informational dialog to make sure you have your connector set up prior to this setting take effect. If your connector is already set up, you may ignore this dialog.
  6. Finish with Assignments and save your policy.

For more details on MAM or app protection policy, see iOS app protection policy settings.

Deploying Microsoft Defender for Endpoint for MAM or on unenrolled devices
