Inbound SCEP from MobileIron VSP Configuration Guide


Use this guide to configure Inbound Simple Certificate Enrollment Protocol (SCEP) from MobileIron VSP settings in a SecureAuth IdP realm.

The Network Device Enrollment Service (NDES) allows software on network and other devices that run without domain credentials to obtain certificates based on SCEP.

SecureAuth IdP supports both Outbound and Inbound from MobileIron SCEP calls.

Inbound SCEP Calls from MobileIron are made when the MobileIron server requests a certificate from SecureAuth IdP via SCEP. SecureAuth IdP can then retrieve a certificate from the Cloud Services, or from an on-premises CA, and MobileIron will provide the certificate to the user.

For Outbound SCEP configuration, refer to the Outbound SCEP Configuration Guide.


1. Have MobileIron VSP and access to the server settings

2. Access to the SecureAuth IdP Web Admin and all Realms requiring Inbound MobileIron SCEP configuration

SecureAuth IdP Configuration Steps


These configuration steps are required in each SecureAuth IdP realm that will be utilizing the Inbound MobileIron SCEP calls

If using MobileIron Inbound SCEP calls to multiple SecureAuth IdP realms, a new Profile will need to be created and configured for each realm


1. In the Policies & Configs section, click Add New - SCEP

2. Set the Name to what will be displayed on the device for this profile, e.g. SA Certificate

3. Select SCEP from the Setting Type dropdown
