This is more a question than a request for support, so feel free to move my post in the appropriate section if it doesn’t fit this one. I didn’t find one, please accept my apologizes if it’s because I missed it.
My situation is quite simple. My own personal Nextcloud server is ranked A+ according to https://scan.nextcloud.com and the one of the institution I work for is ranked F (yes, I triggered a new scan to be sure).
I sync my work between my PCs and my Nextcloud server but, quite often, I need to share documents with teammates. For that, I use federated share, and it works well enough.
Nevertheless, I’m wondering in what extent sharing stuff with someone on a ranked F server puts an A+ server at risk. Is it safe or not?
Thanks for your answer.
