I’m looking for help with file storage. When I work on client sites, I work off an IPad. I typically use Proton Drive or Filen for storage. However, both are blocked by the firewall at a client site. I can connect with it through Proton VPN (only one that bypasses the Firewall, I tried Mullvad, IVPN and many others), but even then, connection can get tricky from time to time and I lose access to files I’m working on at that moment, and have lost several files doing this.
I typically work drafting documents on Collabora Office (which loses connection often on the VPN) and Pages. I’ve thought of switching to iCloud Drive, but was wondering how much better is E2EE in late 2025.
In any event, do folks here use iCloud Drive these days? If not, given the problems with Proton Drive and Filen, any other E2EE services you can recommend? I’ve tried doing Cryptomator to continue ensuring encryption. However, I’ve lost access to folders for some reason, even with a recovery key and the correct password, so I worry about putting too many sensitive files there.
I use iCloud with ADP and it works great, I think it would be a totally fine option as long as you don’t need it to be cross-platform. There is a web interface though if you do.
Thanks. For now I’m working solely on Apple platforms. Are files/filenames, etc fully encrypted once ADP is on? I try storing only what’s required on iCloud.
Since that is not what it actually says, do you have a source to prove that is true?
It seems very unlikely to me, because the reason they store the checksums of the file content in the first place is to deduplicate the files, which they would want to do regardless of file name metadata.
Yeah if the file name were on the list it would be a separate item I think, I also read that as a checksum of the file and file name. They want to deduplicate which means not store identical data, so if the file name is different it’s not identical data and they can’t delete it. They wouldn’t actually need access to the file name to do that, just a checksum of it.
They mention checksums here but not raw file names which I would think would be worth mentioning.
Thanks. Yes, from what I read in the document you attached and understand, file names are not E2EE.
I also forgot to mention that I’ve tried Tresorit and it’s also blocked by the VPN. In fact, just lost a file today I had spent a couple of hours working on. I don’t know why they glitch and get deleted after being saved.
The other recommended option on the site (Peergos) is not practical for my use case because it doesn’t have an iPad app or Files app compatibility.
I have no idea how it happened. All of a sudden, it started saying I was entering the wrong password and never got it to connect again. I had been using Cryptomator on a trial basis, mostly putting non-essential files to make sure it was working properly. Thank goodness this happened before I moved all my work there. I honestly pretty much stopped using it ever since.
That is exactly why they do save the raw file names. Because they only deduplicate based on fine content checksums, and then they return that content with different file names to different customers because they also store the file names with basic security and serve that separately.
