Important Announcements


Apple indirectly announced plans for security requirements changes to recognize newly issued certificates for iOS 13, iPadOS and macOS 10.15 as secure for only 398 days from September 1, 2020, and no longer allow long-term certificates.

Please review the following articles for current requirements and stay tuned for upcoming official announcements:

If your current SSL certificate will expire soon, please purchase your new certificate with a valid period for one year. 


Google has been deprecated device admin in favor of Android Enterprise in the end of 2017. With Android 10 and upcoming Android 11 changes will follow these deprecations, which will affect all customers that are under the legacy management type of Android and Samsung Safe devices. Included are as an example the changes of receiving IMEI Numbers which will take effect in your Hardware Authentication policy which are probably based on the IMEI Number. Beginning with Android 10 these device information is unreceivable for non Android Enterprise managed devices. According to Google's recommendation we want to engage you to plan and start your migration to Android Enterprise within the hardware cycle and setup new devices with Android Enterprise.  

Please compare the following article: 

Additionally and due to its complexity for all Enterprise Mobility Suites, Google deprecated with Android 11 the possibility to use device owner mode with a work profile.  To provide our customers the best user experience with the Android management, Silverback offers all the capabilities given by Google as indicated in the Androids Enterprise Solution Directory

If you want to participate from automated deployments programs for Android or SamsungSafe devices, please refer to the following integrations


Samsung began with Knox 3.0 to harmonize the Knox Platform for Enterprise (KPE) with Android Enterprise (AE). This was to simplify the deployment of enterprise solutions across all Android devices. With Knox 3.4 Samsung deprecated Knox containers and the new model of best practice is to use the Android Enterprise Work Profiles. As such, Silverback 20.0 and on does not support the creation, modification or deployment of Samsung Knox containers to devices. If you have devices that were assigned a Samsung Knox container in a previous version of Silverback , the Samsung Knox container will remain on the device but you will be unable to modify the existing container or add new containers to devices.

A migration to the newer Knox 3.4 requires also a license migration change. With Silverback 20.0 and Companion 20.0 we address the license migration to the new KPE license and we are ensuring a given backward compatibility. The new KPE License key and the legacy ELM license are present under Android in the Settings Administrator area. Due to the cross migration scenario all devices with previous Companions (equal or smaller then 19.0.3) will still work with the ELM key. When the Companion will be updated to the new release version (20.0 and above) and Silverback is an older Version (less than 20.0), the ELM Key will be used. When Silverback and Companion are updated to the release version the migration will take effect. 


As all other companies Matrix42 wants to ensure that all our customers and their employees have the best experience with our products. Due to all new implementations, features and updates it is also necessary to follow market trends and cut off old braids when it is necessary. Due to our long term investment in Android Enterprise we removed with this new version the legacy Android for Work API calls.

Additionally the end of life for Windows 10 Mobile has arrived at the 10th december of 2019. In order to our upcoming release, Silverback 20.0 will be the last version with support for Windows 10 Mobile. Beginning with Silverback 20.0 Update 1 we will deactivate all Windows 10 Mobile related features at all. If you are using Windows 10 Mobile devices, please consider to start with a migration to e.g. iPhone or Android / Samsung Safe devices, soon. 

As part of Mobile Content Management in Silverback, our Matrix42 Documents app provides secure access to corporate documents from Matrix42 Silversync and Microsoft Sharepoint, at any time on any device. Users can navigate through Silversync and Sharepoint, view and download files and read Word documents, PDF files, Excel sheets and PowerPoint presentations. Additionally users can do many operations on files and folders like renaming, moving, deleting, cloning and viewing images format like heic, jpg, png and many others. To harmonize all our user experiences and capabilities we want to inform that all Mobile Content Management scenarios will be from now on supported only in Matrix42 Mobile and Matrix42 Documents application.

While these modes still exist, User Enrollment aims to address Bring Your Own Device (BYOD) deployment scenarios specifically.
