Cryptomator vs Tresorit

At a Glance

If you already pay for cloud storage and only want to encrypt it, Cryptomator is the answer; if you want one zero-knowledge service that handles storage, sharing, and compliance out of the box, choose Tresorit.

These two products often appear in the same searches, but they are not the same kind of thing. Cryptomator, built by Skymatic GmbH in Bonn, is a free open-source tool that encrypts your files before they sync to whatever cloud you already use; it supplies the encryption, not the storage. Tresorit, based in Zurich, is a paid end-to-end encrypted storage service that bundles the cloud, the apps, the sharing, and the certifications into one package. One adds a layer; the other replaces the stack.

What You Actually Get

This is the distinction that decides everything else. Cryptomator does not host a single byte of your data. It creates encrypted vaults that live inside the sync folder of Dropbox, Google Drive, OneDrive, iCloud, or any other service, scrambling each file with AES-256 before that provider can read it. You keep your existing storage, your existing capacity, and your existing sync client — Cryptomator just sits on top of it. The flip side is that nothing works without a separate cloud already installed; the tool has no sync of its own.

Tresorit hands you the whole service. Storage, desktop and mobile apps, web access, file versioning, sync, and an admin console all ship together, with encryption built into every part. You assemble nothing; you sign up and start storing.

Edge: Cryptomator for layering encryption onto a cloud you already trust and pay for.

Pricing & Value

Cryptomator's economics are unusual. The desktop apps for Windows, macOS, and Linux are completely free and fully featured, with unlimited vaults and no account. The only money involved is a one-time purchase of around EUR 14.99 for the iOS or Android app, with no subscription. That low, predictable cost is why it earns a 9.5 for value in our ratings. One catch is worth naming: you still pay your underlying cloud provider separately, and mobile users sometimes expect the whole thing to be free.

Tresorit charges a genuine premium and offers no free tier. Personal runs EUR 12/month (EUR 9 annually) for 500 GB, Professional EUR 24/month for 4 TB, and Business EUR 14/user/month for 1 TB per user. The price covers storage and encryption together, which Cryptomator never includes, but per gigabyte it is far from cheap. That gap shows in its more modest 6.5 value score.

Edge: Cryptomator for raw cost, since the desktop tool is free outright.

Encryption & Security

Both use AES-256 and both are zero-knowledge, but they apply it differently. Cryptomator encrypts each file individually on your device, encrypts filenames with AES-SIV, and derives the key from your vault password using scrypt. Skymatic's servers never touch your data or keys, so there is nothing to breach because nothing is transmitted to them. The cryptographic design is open source under the GPL and was independently audited by Cure53, so you can inspect exactly what it does rather than trust a claim.

Tresorit encrypts every file, folder name, and shared link client-side before upload, holding only meaningless blobs server-side. It cannot be compelled to hand over readable content because it has no keys. The code is not open source, but ISO 27001 and SOC2 Type II certifications stand in as third-party assurance.

Edge: Cryptomator for verifiable, openly audited cryptography you can read yourself.

Ease of Use & Workflow

Cryptomator is approachable for the task it performs: create a vault, set a password, drag files into the virtual drive that mounts on your machine. No technical skill is required, and it earns a high 8.5 ease-of-use score for that simplicity. The friction is conceptual rather than technical. You have to keep two pieces in mind at once, the cloud client and Cryptomator, and remember that anything outside a vault stays unencrypted.

Tresorit asks less of the user because it runs as one coherent service. The desktop app syncs in the background and you work with files as usual. What you give up is convenience that zero-knowledge makes impossible: no server-side search inside files, no previews generated from encrypted content, no browser co-editing. Its 7.5 ease score reflects a smooth but slightly more constrained experience.

Edge: Cryptomator for a lighter footprint that bolts onto habits you already have.

Collaboration & Sharing

Here the platform wins decisively. Cryptomator was not built for sharing with outsiders. A vault is unreadable to anyone without the app and the password, so handing a file to a non-Cryptomator user means taking it out of the vault unencrypted. Cryptomator Hub adds managed team vaults with key distribution, access revocation, and audit logs for organisations, but external collaboration remains a weak spot by design.

Tresorit treats controlled sharing as a core job. A shared link can demand a password, expire on a set date, accept only named recipients, stay view-only, and cap downloads, while an access log shows exactly who opened the file. Encrypted attachments go out as secure links through the Outlook and Gmail plugins, the eSign feature signs documents under eIDAS, and an admin console with Active Directory, Azure AD, and Okta integrations keeps team accounts under control. Neither product offers real-time co-editing.

Edge: Tresorit for granular, auditable sharing with people outside your organisation.

EU & Swiss Compliance

Both clear the bar for European data protection, from different jurisdictions. Cryptomator's Bonn base puts Skymatic squarely under German and EU law, but the stronger point is architectural: because no personal data ever reaches Skymatic, files encrypted before they hit a US cloud become unintelligible blobs, which materially shrinks GDPR exposure. The Cure53 audit gives compliance teams documentary evidence to cite. There are no formal certifications to lean on, though; the assurance is the open code.

Tresorit sits in Switzerland, which holds an EU adequacy decision, and lets customers pin data residency to the EU or Switzerland. It carries ISO 27001 and SOC2 Type II, plus GDPR and HIPAA compliance, earning a perfect 10 in our compliance rating. For regulated buyers who must survive an audit, that certification stack is the deciding factor.

Edge: Tresorit for audit-ready certifications regulated industries demand.

When to Choose Cryptomator

Choose Cryptomator if you already use Dropbox, Google Drive, OneDrive, or iCloud and simply want the files in them to be private. It is the right tool for privacy-conscious individuals, freelancers handling confidential client documents, and small teams that want GDPR-aware encryption without a new subscription or a provider migration. The desktop apps cost nothing, the cryptography is independently audited, and you keep every habit and gigabyte you already have. Go in knowing it provides no storage and no easy external sharing. It is an encryption layer, deliberately narrow, and excellent at exactly that.

When to Choose Tresorit

Choose Tresorit when you want a single service to own storage, security, and sharing rather than assembling them yourself. It suits regulated businesses in finance, healthcare, and legal work, teams that share sensitive contracts or financial reports externally and need expiry dates and audit trails, and organisations that must point auditors at ISO 27001 and SOC2 certifications. You pay a real premium and there is no free tier, but you get zero-knowledge encryption by default, EU or Swiss data residency, an admin console, and identity integrations: a complete platform that a free encryption tool cannot replicate.

The Verdict

These two are less rivals than answers to different questions, and the honest recommendation follows the use case.

Cryptomator is for the do-it-yourself approach: you have a cloud you like, you want it encrypted, and you would rather not pay or switch. Free on desktop, openly audited, and cloud-agnostic, it is the most accessible encryption layer in Europe's open-source ecosystem, as long as you accept that it stores nothing and shares poorly.

Tresorit is for buyers who want the storage, the encryption, and the compliance handled as one product. The price is high and there is no free entry point, but the certifications, data-residency control, and granular sharing make it the stronger choice where a breach would be catastrophic and external collaboration is routine.

For individuals encrypting their own cloud on a budget, Cryptomator is the pick. For businesses needing all-in-one zero-knowledge storage with collaboration and compliance, Tresorit earns its premium. Nothing stops you using both: Cryptomator can encrypt vaults inside any cloud, while Tresorit covers the cases where you need a service rather than a layer.
