Changing communications protocols

Using

BlackBerry UEM

, 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

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.

BlackBerry UEM

Exchange ActiveSync
