Our verdict: Tresorit offers serious end-to-end encryption with apps for every desktop system, including Linux. The free Basic plan is small: 3 GB, two devices, 500 MB per file and no file versions. Inactive free accounts are deleted after 210 days without a login.
About Tresorit
Tresorit encrypts files on your device before upload with zero-knowledge end-to-end encryption, so Tresorit cannot see them. Files live in encrypted folders that you sync to your computer or open through Tresorit Drive in File Explorer. You can share folders with others or send files through encrypted links, and plug-ins for Gmail and Outlook encrypt attachments.
The free Basic plan includes 3 GB of storage, files up to 500 MB, sync on up to two devices and 10 active share links of up to 250 MB, with no credit card. It has no file version history, and you must log in at least once every 210 days or the account and its data are deleted. Paid personal plans start at 50 GB and offer a 14-day trial, which requires payment details.
