There is not. But I’d say keep SSH closed on the NAS or whitelist only your local IP in the firewall. I do that and turn it off when I don’t need it. It can be a bit risqué messing about with SSH on Synology because of how funky they’ve made the distro it’s running and any changes you make might not persist on reboot or after updates.
I’ve been with 1984.is for some time as well. They’re international domain is 1984.hosting. I’ve also had contact with their support and they’re friendly, knowledgeable and straight on point.
I had to transfer my domain and they wanted the domain key. Not wanting to send that over insecure email asked if they have a GPG key and told me they do, sent me a link to their site to get it and a specific mail to send it to which I then was able to send over. The process of contacting them and getting everything set was very speedy and I felt in good hands.
