    GRE, itself, is not encrypted. You can encrypt the data before it goes into the GRE tunnel, but GRE is just an encapsulation. There are other tunnel types that do encryption, but they may not have some GRE features you need, e.g. multicast-capable. – Ron Maupin Nov 20 '18 at 22:20

You should be able to set up IPsec between the two devices. Then run GRE through the IPsec tunnel to allow multicast.

This may help.
