Proton Drive

From the company behind Proton Mail, Proton Drive brings end-to-end encrypted storage into the wider Proton account ecosystem. File contents are encrypted so that the provider cannot ordinarily read them, extending protection beyond encryption used only during transfer or on a server's disk. Its Swiss base places it within a specific legal jurisdiction, although that does not make stored information exempt from lawful processes. A straightforward interface and secure sharing tools make it relevant to everyday document storage as well as sensitive files.

People already using Proton Mail or Proton Calendar can manage these services through the same broader account and subscription ecosystem. A free tier provides limited storage, with paid options for larger needs. Proton Drive suits individuals and teams prioritizing encrypted file storage; its distinction is the privacy model and connection to Proton services rather than a guaranteed value advantage.
