For example, we selected our file share resolution primarily based on its capacity to consolidate different providers we want, resembling group communication, shared calendars, venture administration, on-line enhancing, collaboration, and extra. So, we selected NextCloud on a digital non-public 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 cause we went this route was that it encrypts the info it shops. Hacking our NextCloud will solely get you gibberish recordsdata you possibly can’t learn. It saved us some huge cash implementing our resolution and has free iOS and Android apps.”
