This positions Proton Drive favorably in an area that features well-established incumbents reminiscent of Google Drive, Microsoft’s OneDrive, and Dropbox. The latter of these not too long ago introduced plans to deliver E2EE to its personal cloud storage service, however that’s possible nonetheless a good distance off, plus it’s going to solely be supplied as a perk to enterprise subscribers.

There are inherent challenges in introducing end-to-end encryption into cloud storage providers, significantly throughout a number of platforms (together with the online), which fits a way towards explaining why most corporations working within the area don’t provide E2EE. For starters, it requires constructing completely new frameworks for dealing with the passing of information between level A and level B with out risking exposing any of the info to the middleman service supplier. It additionally requires extra reminiscence and computing energy, and E2EE is usually dearer because it’s tougher to compress knowledge, which in flip results in larger infrastructure and storage prices.

It’s price noting that there are different E2EE cloud storage providers on the market reminiscent of Tresorit, which was acquired by Swiss Put up final 12 months, however Proton Drive is hoping to go a number of steps additional when it comes to its privateness promise.
