Tresorit or Proton Drive: which encrypted cloud should you choose?

Tresorit and Proton Drive play in the same league: two Swiss clouds that encrypt your files end to end, before they even leave your device. On privacy, there is no loser. The real difference lies elsewhere: Tresorit is built for professionals, Proton Drive for you and me. And you read it first on the bill.

The match in one table

Criterion	Tresorit	Proton Drive
Price	From about $13.99/month (billed annually), business plans per user	Free (5 GB). Drive Plus 200 GB at €3.99/month (billed annually)
Free plan	No (no permanent plan)	Yes, 5 GB
Encryption	End-to-end, zero-knowledge	End-to-end, client-side
Jurisdiction	Switzerland	Switzerland
Built for	Companies and sensitive professions	Individuals and families
Ecosystem	Outlook and Gmail integrations	Proton suite (Mail, Calendar, VPN, Pass)

What Tresorit does better

Tresorit doesn’t hide its target: lawyers, doctors, companies that handle confidential documents. Created by cryptography researchers, it builds in GDPR compliance, an ISO certification and fine-grained access control, person by person. If your work requires you to prove that client files are protected, everything is already in place.

Office integration follows the same logic. The service plugs into Outlook as well as Gmail, file sharing is secured and the interface is polished. For a team, those audit and control features justify a higher price. For an individual, they’ll mostly sit unused.

What Proton Drive does better

Price, no contest. The free plan gives you 5 GB to try it out, then Drive Plus moves up to 200 GB for €3.99/month billed annually. Tresorit starts around $13.99/month, with no permanent free plan. Why pay for audit features you’ll never open?

Then simplicity. The interface keeps Google Drive’s landmarks: folders, link sharing, a trash bin. If you know how to use Google Drive, you know how to use Proton Drive. And if your emails are already at Proton, storage lands in the same account, alongside the calendar, the VPN and the password manager. Against Google Drive, my choice is made; it’s also the cloud I use to share files with the outside world.

Verdict

Choose Tresorit if you work with confidential documents and compliance obligations: regulated professions, teams, companies. The price is higher, but it pays for real professional features.

Choose Proton Drive if you’re after an encrypted cloud for your personal life. The same demand for privacy, a much gentler price, and the whole Proton suite on top. For an individual, it’s my recommendation.

Your files still at Google? The guide to leaving Google Drive marks out the path, and if end-to-end encryption isn’t your number one criterion, the Proton Drive vs kDrive match opens a third way. The detailed profiles: Tresorit and Proton Drive, and all the cloud alternatives.
