File/Data Encryption During Export using Informatica

Need guidance around how to encrypt data for an Anaplan export using IICS (Informatica).  As soon as there is an data export and before it hits target (FTP location or Cloud service), data in transit has to be in encrypted status. So I guess, the question is - how do I encrypt the data as soon as export action runs. 

I was reading about BYOK, and will that take care of data encryption and data exported will be in encrypted status.
