Changing communications protocols

Using 

BlackBerry UEM

 or 

Good Control

, you can allow certain secure communications protocols, such as TLSv1.0 or TLSv2, for communication with client devices.

You should be careful when you disable protocols. Check with your organization's IT staff to find out which protocols can be safely disabled. Otherwise, you might disable a protocol that's used on your network, and this can disrupt the secure handshake that's required between 

BlackBerry UEM

or 

Good Control

 and users' devices, and users may receive a “Page Not Found” message.

BlackBerry Access for iOS

 has its own application policy that controls which communications protocol to use.

For more information, see one of the following, depending on your environment:
