Zoom: sovereignty score and 8 European alternatives

Zoom is a communications and collaboration platform that began with video meetings. Its offering covers meetings, webinars, team chat, cloud phone, email and calendar, whiteboards and software for meeting rooms. It also includes a contact centre product, AI features such as note-taking and summaries, and APIs and SDKs for developers. The audience ranges from small businesses to large enterprises, education, healthcare and government. Zoom is delivered as a cloud service through desktop, mobile and web apps; according to the vendor, an on-premises option is also available for its AI features.

Zoom Communications is headquartered in San Jose, California, and has been publicly listed since 2019. Since 2023, paying customers in the European Economic Area can have certain meeting, webinar and team chat data stored in European data centres, with Frankfurt as the first location. According to Zoom, data may still be shared with its US operations in exceptional circumstances. Zoom is not open source. It remains a US provider, so US legislation such as the CLOUD Act can apply.

Why digital sovereignty matters with Zoom

Zoom is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Zoom hosts data in US, EU. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

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