Set up iOS or iPadOS device with Company Portal and DISA Purebred

  • บทความ

Enroll your device with the Intune Company Portal app to gain secure, mobile access to your organization's email, files, and apps. After your device is enrolled, it becomes managed. Your organization can assign policies and apps to the device through a mobile device management (MDM) provider, such as Intune.

During enrollment, you'll also install a derived credential on your device. Your organization might require you to use the derived credential as an authentication method when accessing resources, or for signing and encrypting emails.

You likely need to set up a derived credential if you use a smart card to:

  • Sign in to school or work apps, Wi-Fi, and virtual private networks (VPN)
  • Sign and encrypt school or work emails using S/MIME certificates

In this article, you will:

  • Enroll a mobile iOS or iPadOS device with Intune Company Portal.
  • Get a derived credential from your organization's derived credential provider, DISA Purebred: https://cyber.mil/pki-pke/purebred/.

What are derived credentials?

A derived credential is a certificate that's derived from your smart card credentials and installed on your device. It grants you remote access to work resources, while preventing unauthorized users from accessing sensitive information.

Derived credentials are used to:

  • Authenticate students and employees who sign in to school or work apps, Wi-Fi, and VPN
  • Sign and encrypt school or work emails with S/MIME certificates

Derived credentials are an implementation of the National Institute of Standards and Technology (NIST) guidelines for Derived Personal Identity Verification (PIV) credentials as part of Special Publication (SP) 800-157.

Prerequisites

To complete enrollment, you must have:

  • Your school or work-provided smart card
  • Access to a computer or kiosk where you can sign in with your smart card
  • Your mobile device
  • The Intune Company Portal app for iOS and iPadOS installed on your device

You'll also need to contact a Purebred agent or representative during setup.
