PRA-DATA AT REST ENCRYPTION INBUILT AVAILABLE?

The  Encryption page on the appliance through /appliance web interface enables encryption for session data stored on the appliance. The appliances must be running on Base 5.0 or higher. See PRA docs Encryption

If you are using the Integration Client there is no feature within the IC to encrypt the recordings that are copied to the external storage. That would need to be implemented through the windows server itself.

I hope this helps.
