TeamSpeak: sovereignty score and 8 European alternatives

TeamSpeak is voice communication software that uses a client-server design. Communities, gaming groups and teams run their own TeamSpeak server and connect with a client application that supports voice chat, text chat, file sharing and screen sharing. For users without their own hardware, hosted server space is offered through the TS Official Communities platform. The software is proprietary: the client and server are distributed as proprietary freeware rather than as open source.

The privacy policy names two controllers: TeamSpeak Systems GmbH, with its registered seat in Krün, Germany, and TeamSpeak Systems, Inc., a US company based in Chula Vista, California. The policy states that the company operates internationally and may transfer personal data to the United States and other countries, but it does not name the countries where hosted servers are located. For a European organisation, the German entity and self-hosting on its own infrastructure are the relevant points. The US entity and transfers to the United States should be assessed against its data transfer requirements and any third-party processors.

Why digital sovereignty matters with TeamSpeak

TeamSpeak 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.

TeamSpeak runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

TeamSpeak is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

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