Kopano: sovereignty score and 8 European alternatives

Kopano Cloud is a groupware product for email, calendar, notes, tasks and contacts. It supports native Outlook, ActiveSync for mobile devices and POP3/IMAP. Administrators get a self-management interface, a REST API and an agent for synchronising LDAP or Active Directory. The product is delivered as a software stack of OCI containers (Docker) with a multi-tenant architecture. Kopano Cloud is the successor to Kopano Groupware, which descends from Zarafa; support for that older suite has ended.

Kopano Groupware was released under the AGPL-3 licence, but Kopano Cloud is not available under an open-source licence. Customers can host the containers where they choose; according to the vendor, data is then subject to the local privacy laws of the hosting location, so hosting in the EU means EU law. The hosting country is a choice of the customer or partner. European organisations can run it themselves or through a partner in a European data centre, but the source code of the current version cannot be freely inspected or forked.

Why digital sovereignty matters with Kopano

Kopano is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Kopano scores best on data residency.

Kopano is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

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