Overview
Tresorit is an end-to-end encrypted cloud storage service based in Switzerland. Unlike mainstream services like Google Drive and Dropbox, Tresorit encrypts your files on your device before uploading them, and only you hold the decryption keys. Even Tresorit's employees cannot access your data. This zero-knowledge architecture makes it one of the most secure cloud storage options available.
The service is particularly popular with professionals in regulated industries who need to store and share sensitive documents securely while maintaining compliance with GDPR, HIPAA, and other frameworks.
Security and Compliance
Tresorit uses AES-256 encryption for data at rest and TLS for data in transit. All encryption keys are derived from your password and never leave your device unencrypted. The service holds ISO 27001 certification and complies with GDPR and HIPAA requirements. Shared links can be password-protected, set to expire, and restricted to specific email addresses, giving you granular control over who accesses your files.
Who Should Use It
Tresorit is ideal for professionals and organisations that handle sensitive data and need verifiable security. Solicitors, accountants, healthcare providers, and anyone subject to data protection regulations will benefit from the compliance credentials. For casual personal use, the cost may be difficult to justify when free encrypted alternatives exist, but for professional use, the investment is worthwhile.
