Encrypted Cloud Storage Compared (2026)
Compare the top encrypted cloud storage services — Tresorit, Proton Drive, Sync.com, and others.
Why Encrypted Cloud Storage?
Standard cloud storage (Google Drive, Dropbox, iCloud) encrypts data in transit and at rest, but the provider holds the encryption keys. They can access your files. They can be compelled to hand them over.
End-to-end encrypted (E2EE) cloud storage encrypts files on your device before upload. The provider never has the keys. Even if breached or subpoenaed, your files remain encrypted.

Tresorit: Swiss-based, E2EE, SOC 2 compliant, excellent sharing features. 1TB from $10/mo. Best for business users.
Proton Drive: Swiss-based, E2EE, integrated with ProtonMail ecosystem. Free tier with 1GB. Growing feature set. Best for ProtonMail users.
Sync.com: Canadian-based, E2EE, affordable. 2TB from $8/mo. Good balance of features and price.
Filen: German-based, E2EE, open source. 10GB free, 2TB from $12/year. Best budget option.
Icedrive: Welsh-based, Twofish encryption, unique virtual drive feature. 10GB free.

Encrypted cloud storage and dead man's switches serve different purposes:
Cloud storage: ongoing secure file storage and sync. Dead man's switch: conditional file delivery upon inactivity.
