Tresorit
US alternative: DropboxEnd-to-end encrypted cloud storage and secure collaboration product for organizations handling confidential files and workflows.
Fully European
Overview
Tresorit is a secure cloud storage and collaboration product designed for organizations that prioritize confidentiality, governance, and controlled file sharing. It competes credibly with Dropbox-style business storage while differentiating on end-to-end encryption and privacy posture. Official materials confirm that Tresorit is part of Swiss Post and describe its secure collaboration focus, while public company profiles provide the founding year and Swiss headquarters. This is a strong European secure-storage candidate for Antimaga.
