Tresorit Review 2026: Tested for 60 Days
Our verdict
Tresorit is the most secure encrypted cloud storage available. It’s the only provider that passed the ETH Zurich 2024 vulnerability study largely unscathed, holds GDPR, HIPAA, and ISO 27001 compliance certifications, and is backed by Swiss Post. After 60 days of testing, we found its encryption implementation bulletproof, though you’ll pay a premium for it.
If you handle sensitive data in healthcare, legal, or finance, Tresorit is the clear choice.
