OneDrive is Microsoft's file sync and sharing service, bundled into Microsoft 365 and wired into Windows and Office by default. Accounts start at 5 GB free, with storage bundled into the 365 subscriptions above that. Microsoft is headquartered in Redmond, and as a US provider it falls under the CLOUD Act even when data sits in an EU region.

About Tresorit

Tresorit is a Swiss end-to-end encrypted cloud storage and file collaboration platform with a zero-knowledge architecture: files are encrypted on your device before upload, and only you and explicitly authorised recipients can ever decrypt them. It holds the broadest compliance portfolio of any EU cloud storage solution: GDPR, HIPAA, ISO 27001, SOC 2, TISAX, ITAR, NIS2, and DORA.

Teams share files through encrypted tresor folders with granular access controls, watermarking, and the ability to revoke shared links instantly. Tresorit Engage provides secure data rooms for client and partner collaboration, while an eDiscovery module helps legal and compliance teams locate and export documents for regulatory requests.

Key benefits:

  • Zero-knowledge E2E encryption means even Tresorit cannot access your files
  • Encrypted team folders with granular permissions and instant access revocation
  • Secure external sharing with password-protected, time-limited links
  • HIPAA, TISAX, ITAR, and DORA compliance for heavily regulated industries
  • eDiscovery module for locating files in response to legal and compliance requests
  • Tresorit Engage with secure data rooms for client and partner document exchange
  • Watermarking to trace leaked documents back to the source
  • Available on Windows, macOS, iOS, Android, and web

Tresorit is headquartered in Zug, Switzerland, with operations in Budapest, Hungary. All data is stored on EU and Swiss infrastructure with customer-selectable data residency. Swiss law and GDPR govern all data handling, and the platform undergoes regular independent security audits with no U.S. entities involved in storage or processing.

Trusted by law firms, financial institutions, healthcare providers, and automotive manufacturers across Europe for provably secure file storage and external collaboration.

Why choose Tresorit over OneDrive?

The decisive argument is data jurisdiction. OneDrive is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.

Tresorit removes that overhead. As a Switzerland-based provider, it operates under Swiss FADP + GDPR for EU users, and data stays in Switzerland, which the European Commission recognises as offering an adequate level of protection. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
