**Short answer:** Tresorit for enterprise-grade E2E, Filen for open-source, Proton Drive if you're in the Proton ecosystem, OnionShare for transient peer-to-peer transfer.

For end-to-end encrypted cloud storage in 2026, Tresorit is the most mature option (Swiss, audited, enterprise-grade) but it is closed-source and now Swiss-Post-owned. Filen and Internxt are the open-source alternatives — both German and Spanish operators respectively, with E2E and crypto payment. Proton Drive integrates with the Proton suite and is the convenient choice for existing Proton users. Mega has a large free tier but the 2022 cryptography analysis is a caveat. For transient file transfer without any operator in the path, OnionShare runs a temporary Tor onion service from your own machine — the strongest no-operator posture but not a storage product.
