Both providers are zero-knowledge. The difference is what Proton Drive doesn't do: team chat, calls and shared rooms.
Proton Drive is part of a broader privacy suite anchored in Switzerland, and it does encrypted file storage well. What Proton Drive doesn't do is team chat, group calls and shared team rooms inside the same product — those live in separate apps or not at all. DRIVUNO combines the encrypted drive with Rooms (channels, DMs, threads), end-to-end encrypted calls and a Team Drive per room, on one account: files yes, plus chat, calls and rooms.
DRIVUNO is a zero-knowledge Dropbox + Slack: files, chat and mail are encrypted on your device, the keys never leave it, 1 GB free, paid plans from $9.99/month.
