By default the bulk of the mobile device connection is not encrypted. If you would like to enable full encryption this can be done in the Mobile Server Profile by selecting either Transport or Strict, see below for details between the two. Once you enable this you would need to perform a deployment to push this to the mobile device server.
Avalanche offers two options for encryption:
Matches the level of encryption with the capacity of the mobile device. Communication between the mobile device server and mobile devices will be encrypted to the degree possible.
Strict Transport Encryption
Uses AES encryption for information. Only Enablers that support AES encryption (Enabler 5.0 or newer) will be able to connect to the server when strict transport encryption is enabled.
