## Verdict

Tresorit is the enterprise-leaning end-to-end-encrypted storage option. Swiss jurisdiction and Swiss Post ownership are the operator-side context to factor in. Solid encryption, mature product, account-bound.

## Strengths

- End-to-end encryption at rest with operator never holding plaintext keys.
- Mature enterprise-grade product; consistent audits.

## Caveats

- Operator is now Swiss Post-owned; review the corporate context for your threat model.
- Email at signup binds the account.
- Closed-source clients.
- Facts need re-verification by operator (last seeded 2026-01).
