Securely store, share, and collaborate on sensitive files with end-to-end encryption. Features include data rooms, eSign, secure email, and data residency.
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.

The platform combines Nextcloud Files (storage and sync), Nextcloud Talk (chat and video), Nextcloud Groupware (calendar and contacts), and Nextcloud Office (real-time document editing) in a single installation.

- Nextcloud Talk for end-to-end encrypted video calls and chat with no external service

The platform is GDPR-native, supports HIPAA-capable configurations, and is used by major EU governments, universities, and public institutions that mandate on-premises data sovereignty.

Virtual project drive for CAD, BIM, point-cloud and media files: local-feeling access on Windows and macOS, safe file locking, immutable version recovery, EU-hosted.
Orbifs turns terabytes of heavy project files into an ordinary drive on Windows and macOS. CAD, BIM, point-cloud and media files stream on demand from a virtual project drive, so nobody waits for a full sync, fights a VPN, or overwrites a colleague's work with a stale copy.
Native desktop clients mount the drive like a local disk. Safe file locking keeps a single writer on Revit, ArchiCAD or AutoCAD models while everyone else reads, and a LAN cache (beta) brings office-network speed to large opens. Admins get audit export, and the Business plan adds SSO/SAML.
Key benefits:
- Virtual drive files appear local on Windows and macOS with no sync conflicts
- File locking one writer at a time on CAD and BIM models
- Immutable recovery roll back ransomware or accidental deletes from protected versions
- LAN cache office-network speed for heavy file opens (beta)
- Team plans 1 to 15 TB and 5 to 50 seats, from 69 euros per month
- Admin controls audit export on every plan, SSO/SAML on Business
Orbifs stores data in France on OVHcloud infrastructure, replicated across multiple EU data centres and governed by European law. The company behind it, Archi Systems AS, is based in Oslo, Norway (EEA), so GDPR applies by default and there is no US CLOUD Act exposure; a signable DPA and a CSA STAR Level 1 self-assessment are published.
Ideal for architecture and BIM studios, surveyors, contractors and media teams that want Dropbox-simple access to files far too heavy for Dropbox.
