ZendTo: sovereignty score and 8 European alternatives

ZendTo is a web-based system for exchanging large files, aimed at organisations that cannot or do not want to send them by email. You run it yourself on a Linux or Unix server or in a virtualisation environment. According to the project site, it offers encryption of uploads with a user-chosen passphrase, checksums, single-use download links, chunked uploads for large files, and integration with Active Directory, OAuth, SAML, LDAP or IMAP.

ZendTo is developed by a single individual developer in the United Kingdom, without a company or foundation behind it. According to the Comptoir du Libre catalogue it is licensed under the GNU GPL v2; the project site itself names no licence. The latest release consulted is 6.15-8 from June 2025. The developer states that commercial support is not available, and there is no hosted service. Because you run the software on your own server, files and metadata stay on your own infrastructure.

Why digital sovereignty matters with ZendTo

ZendTo is headquartered in GB, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

ZendTo hosts data outside the EU (OTHER). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

ZendTo 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 ZendTo together with your other vendors and gives a total score, a heatmap and the main risk drivers.
