Tresorit: sovereignty score and 8 European alternatives

Tresorit is an end-to-end encrypted cloud storage and collaboration platform aimed at businesses. Its products include SecureCloud, Engage (secure data rooms), FileSharing, an eSign add-on and email encryption for Outlook and Gmail. Sharing can be protected with passwords, expiry dates and download limits. Administrators get access policies, audit logs, remote or local wipe, single sign-on with Azure AD, Okta or Google, and custom branding for client workspaces. According to Tresorit, files are encrypted on the user's device before upload and only the user and the intended recipients hold the keys.

Tresorit was founded in 2011, belongs to Swiss Post (Swiss Post Digital) and has offices in Switzerland, Germany and Hungary. Customers can choose EU-only data residency or one of 12 global locations; the FAQ mentions storage in the EU, the United States or Switzerland. Tresorit is a service hosted by the vendor. For a European organisation, the region selected therefore determines the jurisdiction of the stored data.

Why digital sovereignty matters with Tresorit

Tresorit is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

Tresorit hosts data in EU, CH, US, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Tresorit is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Tresorit together with your other vendors and gives a total score, a heatmap and the main risk drivers.
