Certificate-based Trusted Endpoint verification for MobileIron Cloud will reach end-of-life in a future release. Migrate existing iOS Certificate Configuration management integrations to iOS Configuration. Learn more about the end-of-life timeline and migration options in the Duo Trusted Endpoints Certificate Migration Guide.
Duo's Trusted Endpoints feature secures your sensitive applications by ensuring that only known devices can access Duo protected services. When a user authenticates via the Duo Prompt, we'll check for the access device's management status. You can monitor access to your applications from managed and unmanaged devices, and optionally block access from devices not managed by your organization.
Trusted Endpoints is part of the Duo Beyond plan.
Before enabling the Trusted Endpoints policy on your applications, you'll need to deploy the Duo device certificate or REST API access for Duo to your managed mobile devices. This guide walks you through Ivanti Neurons configuration for Android and iOS mobile devices.
These instructions are for the cloud-hosted Ivanti Neurons service, formerly known as MobileIron Cloud and Ivanti Secure UEM. If you are using MobileIron Core, see our instructions for the on-premises MDM instead.
Duo determines trusted device status on Android devices using Duo Mobile installed and activated for Duo Push on a given device to verify device information. To enable this verification you'll need to grant Duo read-only access to those devices via your Ivanti Neurons MDM's API access.
You must have already configured Android Enterprise and Work Profiles in Ivanti Neurons/MobileIron Cloud.
The new MobileIron Cloud integration is created in the "Disabled" state. You'll turn it on when you're ready to apply your Duo trusted endpoints policy.

New MobileIron Cloud certificate deployment management integrations may no longer be created as of October 2021. Consider migrating your certificate-based iOS MobileIron Cloud integration to MobileIron Cloud with App Config. See the Duo Knowledge Base article Guide to updating Trusted Endpoints iOS integrations from certificates to AppConfig for more information about migrating your iOS certificate-based management integrations to App Config.
These instructions remain available for customers who created these integrations before October 2021 and may need to reconfigure them. Duo continues to support existing MobileIron Cloud iOS certificate deployments and will do so until the integration reaches end-of-life status in a future update.
Duo verifies the trusted status of iOS devices by checking for the presence of a Duo device certificate. You'll use MobileIron Cloud to push the Duo CA information to your mobile devices so they can obtain a Duo certificate.
The new MobileIron Cloud integration is created in the "Disabled" state. You'll turn it on when you're ready to apply your Duo trusted endpoints policy.
Keep the Duo Admin Panel open in your browser. You'll need to refer back to the MobileIron Cloud management integration page to complete the iOS configuration steps.
Log on to the MobileIron Cloud admin portal as an administrator and navigate to Admin → Connectors. Click Download the Connector to obtain the Cloud Connector installation ISO.
Deploy the MobileIron Cloud Connector in your on-premises VMWare environment, following the setup instructions in the Connector Installation Guide.
Ensure that your Connector successfully registered with your MobileIron Cloud tenant and has green online status on the Connectors page in the MobileIron admin portal before continuing on with the Duo CA configuration.
In the MobileIron Cloud admin portal, navigate to Admin → Certificate Authority and click the Add button.
Click the Continue button under the "Add an External Certificate Authority" option on the "Add Certificate Authority" page.
Enter the Duo Certificate Authority (CA) information from step 2 of the iOS Configuration Instructions on the MobileIron Cloud management integration page in the Duo Admin Panel as follows:
| Name | Enter a descriptive name, like "Duo CA". |
| Certificate Authority Type | Microsoft |
| SCEP URL | Paste in the SCEP URL from the "Add an External Certificate Authority (CA)" section of the iOS instructions on the MobileIron Cloud management integration page in the Duo Admin Panel. |
| Username | Paste in the Username from the "Add an External Certificate Authority (CA)" section of the iOS instructions on the MobileIron Cloud management integration page in the Duo Admin Panel. |
| Password | Paste in the Password from the "Add an External Certificate Authority (CA)" section of the iOS instructions on the MobileIron Cloud management integration page in the Duo Admin Panel. |
| Challenge URL | Paste in the Challenge URL from the "Add an External Certificate Authority (CA)" section of the iOS instructions on the MobileIron Cloud management integration page in the Duo Admin Panel. |
Click Save after entering all the required information to move to the next steps of adding an identity certificate configuration.
Go to the Configurations page using the top navigation. With the Default Partition selected in the far left drop-down menu, click the Add button.
Locate the Identity Certificate configuration type and click it to begin adding the new Duo configuration.
Enter the Identity Certificate configuration information from the MobileIron Cloud management integration page in the Duo Admin Panel as follows:
| Name | Enter a descriptive name, like "Duo Trusted Endpoints". |
| Description | Enter additional information about this new configuration, if desired. |
| Certificate Distribution | Dynamically Generated. |
| Source | Select the Duo CA you added earlier. |
| Signature Algorithm | SHA256 with RSA |
| Subject | Paste in the Subject from the "Add a Configuration" section of the iOS instructions on the MobileIron Cloud management integration page in the Duo Admin Panel. |
| Key Size | 2048 |
| Use as digital signature | Check the box next to this option. |
Click Test Configuration and Continue after entering all the required information.
If the Duo CA and the configuration information is correct then you'll see the "Configuration test successful" page, which also shows you your Duo certificate information. Click Next to continue.
If the configuration test fails, double-check that the information entered for the Duo CA was correct, and that your Connector registered successfully and has "On" status in the MobileIron admin portal.
On the last page of the "Create Identity Certificate Configuration" setup you can choose which devices receive the new Duo configuration. Enable the configuration by checking the Enable this configuration box, and then click the Custom option to select the device group that contains your managed iOS devices.
Click Done after selecting your iOS device groups for configuration distribution.
Repeat steps 2 through 7 again for each additional partition in the drop-down list on the "Configurations" page.
At this point the configured integration is disabled and applies to no users until you finish your deployment.
Once your Ivanti Neurons managed devices receive the Duo config you can set the Trusted Endpoints policy to start checking for managed device status as users authenticate to Duo-protected services and applications.
When your trusted endpoints policy is applied to your Duo applications, return to the MobileIron Cloud trusted endpoint management integration in the Admin Panel. The "Change Integration Status" section of the page shows the current integration status (disabled by default after creation). You can choose to either activate this management integration only for members of a specified test group or groups, or activate for all users. If you created more than one MobileIron Cloud integration, you must activate each one individually.
The Device Insight and Endpoints pages in the Duo Admin Panel show which access devices are trusted/managed.
Users with Duo Mobile installed and activated for Duo Push on Android and iOS devices see a device trust dialog when authenticating to a protected resource via the Duo Prompt.
Duo uses the API access you granted In Ivanti Neurons to perform a permissions check to verify device information.
If Duo successfully verifies the device information using the MobileIron API access, and the user has Duo Mobile activated for Duo Push, then the user receives a login request on their phone.
On Android devices, approving the request grants access and returns the user to the protected application. On iOS devices, after approving the Duo authentication request users tap the top-left of the Duo Mobile app to return to the application and complete login. The "Second Factor" logged for these approvals is shown as "Duo Mobile Inline Auth" in the Duo authentication log.
If the user does not have Duo Mobile activated for push, or does not approve the Duo request before it times out, the user returns to the Duo Prompt, where they may select from the available factors to complete 2FA.
With the legacy iOS certificate configuration, iOS users will see a prompt asking them to choose a certificate when authenticating to a protected resource via the Duo prompt. After selecting the Duo Device Authentication certificate and completing authentication, subsequent Duo authentications from the same device will automatically use that same certificate for verification.
Deleting a trusted endpoints management tool integration from the Duo Admin Panel immediately invalidates issued Duo device authentication certificates. Be sure to unassign your trusted endpoints policy from all applications or remove the "Trusted Endpoints" configuration item from your global policy before deleting an existing MobileIron Cloud integration from "Trusted Endpoints Configuration". You should also disable your Duo admin user in Ivanti Neurons.
Leaving the policy settings in place after deleting a management tools integration may inadvertently block user access to applications.
