Proton Drive is the encrypted choice from the company behind Proton Mail. Files are end-to-end encrypted on every plan, so Proton says it cannot read them, and the free plan gives 5 GB with the same encryption. Drive Plus adds 200 GB and 10 years of previous file versions for $4.99 monthly or $2.49 a month billed $29.88 yearly on the current offer. Proton Unlimited adds 500 GB plus Proton VPN, Mail, Calendar and Pass, and Proton Family covers up to 6 users with 3 TB. Online document and spreadsheet editors work inside the encrypted drive, and shared links can carry passwords and expiry dates. The trade-offs are capacity and price clarity. Personal plans stop at 3 TB, the cheapest tier is small for photo libraries, and the advertised prices are discounted yearly rates, so check the renewal price before committing.
Who it is for
Privacy-focused individuals and families who want encrypted storage plus encrypted email and a VPN on one bill.
