Is it "safe" to run a Proxmox VE cluster on a public network?

Hello folks,

I would like to build a Proxmox VE cluster on base of three or four Hetzner dedicated root servers, which can be virtually connected to a Hetzner vSwitch, residing in different datacenters. ZFS-replication and live migration is done by (encrypted) ssh - as I know.
I would like to know if it is necessary to encrypt the remaining (internal) cluster traffic, because the Hetzner vSwichtes don't do any out-of-the-box-encryption.

Best regards,
mscd
