Icedrive Review 2026: Budget Encrypted Cloud Storage Tested
Our verdict
Icedrive is an attractive budget option with lifetime plans and a clean interface, but it comes with a serious caveat: the ETH Zurich 2024 security study found vulnerabilities in its encryption implementation, and Icedrive chose not to address them. This is a deal-breaker for high-security use cases.
For casual encrypted backup with a one-time payment, Icedrive’s lifetime plans offer genuine value. For sensitive files, choose Tresorit or Proton Drive.
