Alternatives to Tresorit
Zero-knowledge encrypted file sharing for businesses.
10 hand-curated alternatives from MintedSaaS's directory. See the Tresorit listing →
Tresorit is a zero-knowledge encrypted file-sharing and sync service built for teams that need compliance-grade security without touching the underlying infrastructure themselves. It positions itself as a replacement for mainstream tools like Google Drive and Dropbox when privacy regulations or contractual data-protection requirements rule out US-based cloud storage. The service encrypts data client-side before upload, meaning Tresorit itself can't decrypt your files, and it's sold primarily to regulated industries: financial services, healthcare, law firms, and public-sector organizations that operate under GDPR, HIPAA, or similar frameworks.
Tresorit's typical workflow involves replacing or supplementing the generic file-sync tools a team already uses. Employees sync folders to their machines, share encrypted links with external parties, and rely on Tresorit's permission controls to manage who can access what. Teams choose it when their security or compliance profile demands encryption-at-rest, client-side encryption, or a non-US data center. The buyer is usually a compliance officer, IT director, or security team lead evaluating whether a standard cloud-storage platform meets contractual obligations—rather than a user looking for the cheapest or most feature-rich option.

What to look for
- Whether the service encrypts data client-side before upload, so the vendor cannot decrypt files without your key.
- Whether the service publishes a Data Processing Agreement and third-party security audit or SOC 2 certification.
- Whether the service is based outside the United States and operates its own data centers rather than renting cloud infrastructure.
- Whether you can revoke access to shared links or files after they've been distributed, without deleting the original.
- Whether the team-admin console supports granular folder-level permissions, password protection, and expiration dates on shared links.
- Whether the service offers a free tier or trial period without requiring a credit card or sales call to evaluate.
FAQ
What are the best alternatives to Tresorit?
Proton Drive, Sync.com, Cryptomator, and Internxt all offer zero-knowledge architecture where the vendor can't access your files. Proton Drive is Switzerland-based and bundles drive with email security. Sync.com is Canadian and targets compliance buyers directly. Cryptomator is open-source and self-hostable. Internxt is privacy-focused and cheaper than Tresorit.
Are there free alternatives to Tresorit?
Cryptomator is free and open-source, and Filen offers a free tier with 10 GB. Neither includes the same compliance certifications or team-management features Tresorit does, but they're viable for individuals and small teams with zero budget.
Which encrypted file-sharing tools are GDPR compliant?
Tresorit, Proton Drive, Sync.com, and Internxt all emphasize GDPR compliance and operate under EU or Swiss data protection law. Each publishes a Data Processing Agreement, though you should verify which EU data center your files land in and whether the vendor has been audited.
Can I use zero-knowledge file storage if my team is international?
Yes, but file-sync latency and access speeds may vary by location. Proton Drive, Sync.com, and Internxt operate servers across multiple regions, so team members in different countries can sync without relying on a single data center.
What's the difference between Tresorit and pCloud or Dropbox?
Tresorit and Sync.com use zero-knowledge encryption, meaning the vendor can't decrypt your data. pCloud and Dropbox encrypt data in transit and at rest, but the vendor holds the keys and can access files if served a warrant. That tradeoff matters for regulated industries; casual users usually don't notice the difference.
Do I need to use a VPN with encrypted file-sharing tools?
No. Tools like Tresorit, Proton Drive, and Cryptomator encrypt on your device before data leaves it, so a VPN adds no additional security. You'd use a VPN for anonymity or to mask your IP, but that's separate from file encryption.
How do I pick between client-side and server-side encryption?
Client-side encryption (Tresorit, Cryptomator, Proton Drive) means the vendor never touches unencrypted data, which suits compliance buyers. Server-side encryption (Google Drive, Dropbox) is easier to integrate with third-party apps but requires you to trust the vendor's key-management practices.
Which zero-knowledge tools offer team collaboration and permissions?
Tresorit, Proton Drive, Sync.com, and MEGA all support granular folder permissions, guest-link sharing, and team accounts. Cryptomator and Internxt have simpler sharing—better for individuals or static folder hierarchies than dynamic team workflows.
