Cyberduck: sovereignty score and 8 European alternatives

Cyberduck is a libre server and cloud storage browser for Mac and Windows, developed by iterate GmbH. From one interface you connect to FTP, SFTP, WebDAV and SMB servers and to storage services such as Amazon S3, OpenStack Swift, Backblaze B2, Microsoft Azure and OneDrive, Google Drive, Dropbox, Box, DRACOON and Nextcloud. The same developer also makes Mountain Duck, which shows remote storage as a drive in Finder or File Explorer.

Cyberduck is open source under the GNU General Public License version 3 and is installed as an application on your own device. The vendor does not operate any storage itself: according to its privacy statement, no user data is collected or shared and data is processed solely on your device. Only crash reports carry an IP address. Where your files are stored is therefore decided by the service you connect to. iterate GmbH is headquartered in Bern, Switzerland; no foreign owner is named. Switzerland is not in the EU but is an EFTA country with an EU adequacy decision for data protection.

Why digital sovereignty matters with Cyberduck

Cyberduck is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

Cyberduck hosts data in Switzerland only. Switzerland is not part of the EU or the EEA, so the GDPR does not apply there directly; the European Commission does recognise Swiss data protection as adequate, so personal data can go there without extra safeguards. Our model therefore scores it between EU hosting and hosting outside Europe. If you require strictly EU hosting, take this into account.

Cyberduck is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Cyberduck together with your other vendors and gives a total score, a heatmap and the main risk drivers.
