So, we selected NextCloud on a digital personal server. One SSL certificates covers every part it does for us. We use a static IP from our web service supplier and implement safe connections solely. The second purpose we went this route was that it encrypts the information it shops. Hacking our NextCloud will solely get you gibberish recordsdata you’ll be able to’t learn.
