Update: December 12, 2018 - The latest update to the Intune Company Portal has been released. The iOS and macOS company portals will now enforce Apple's updated Application Transport Security (ATS) requirements, which also require TLS 1.2+. New PowerShell script link added below.
Update: September 10, 2018 - The Company Portal will support TLS 1.2 in time for broader Microsoft move to TLS 1.2 by October 31, 2018.
Update: April 7, 2018 – We will no longer be listing an iOS Company Portal version in Apple TestFlight to test ATS compliance because we have not heard any updates from Apple on the status of this change.
Update: November 13, 2017 – Added in macOS Company Portal information. Note, if you’ve already tested and everything works with the iOS Company Portal app in TestFlight (currently version 2.9.1), the macOS Company Portal will also work once this change takes place.
Update: November 1, 2017 – Still no updated timeline from Apple on when this change will be enforced. We recently uploaded a new version (2.9.1) of the iOS Company Portal app into TestFlight, because the previous version (2.7.1) hit the 90-day expiration set by Apple.
Update: August 15, 2017 – Still no updated timeline from Apple on when this change will be enforced. If you validated that the ATS-enforcing Company Portal app in TestFlight works in your environment and tested with Apple’s nscurl tool, then no action is needed until Apple makes this change.
We recently uploaded a new version (2.7.1) of the iOS Company Portal app into TestFlight, because the previous version (2.5.1) hit the 90 day expiration set by Apple.
Update: May 10, 2017 - We added a few additional links for more information.
Update: May 3, 2017 – We heard from several of you that you’d like us to wait to release the new version of the Company Portal app until Apple releases their Application Transport Security (ATS) change. Apple has not yet provided a date for the change, but when Apple enforces it, the iOS and macOS Company Portals will have to release app updates to enforce it as well. We are making an updated version of the iOS Company Portal with the change available through the Apple TestFlight program. If you would like to test a version of the iOS Company Portal that enforces the new ATS requirements, so you can test your compliance, email CompanyPortalBeta@microsoft.com with your first name, last name, email address, and company name.
Apple has announced that they will enforce specific requirements for Application Transport Security (ATS). ATS is used to enforce stricter security on all app communications over HTTPS.
This has an impact on Intune customers using the iOS Company Portal app and the macOS Company Portal app.
To ensure you comply with these new requirements, make sure that all your network connections configured for use within the iOS Company Portal app and the macOS Company Portal app meet Apple’s new requirements. Some places to check include ADFS configuration, proxy server configuration, and any custom links set in the Admin Console like the support website URL.
