You can choose whether data is encrypted during transfer.

If you are using the HTTP(s) protocol, which is the default protocol used by vCloud Connector for data transfer, data is encrypted by default. You can deselect or select data encryption by setting the Disable SSL or Enable SSL option on the destination vCloud Connector node. SSL is enabled on vCloud Connector nodes by default.

If you are using the UDT protocol, data is transferred as plain text by default. You can select data encryption by selecting the Enable Encryption option on the destination vCloud Connector node. Note that selecting this option is the only way to enable encryption with UDT. The SSL setting has no effect on UDT transfer; it only applies to HTTP(s) transfer.

You should be aware that there is some performance loss associated with encryption.
