TC55 and SOTI MobiControl - encryption?


We are looking to encrypt our TC55 devices and note that SOTI offers internal / external encryption for various manufacters but not Motorola Solutions.
This seems surprising considering the close relationship between Motorola and SOTI. Does anyone have any insights why encryption isnt offered for any Motorola / Zebra devices?
Edit: It turns out that encryption IS supported after all despite what is shown here. I think the graphic refers to Motorola Mobility rather than Motorola Solutions. Just enable the policy and it will send the relevant MDM command.
