iCloud Files is the only major cloud file syncing service that is e2e encrypted afaik. Was my reason to migrate over from OneDrive (especially since I was already using Apple devices and paying for iCloud for photos anyway).
Thanks! I would use iCloud, but I have a few windows devices I need for work unfortunately. It doesn't let me use the advanced security and maintain a windows device. Ironically, like many of these services I already have an Apple One subscription and am paying for it anyways.
