Yeastar: sovereignty score and 8 European alternatives

Yeastar is a Chinese provider of IP PBX systems and cloud PBX services for businesses. Its P-Series phone system is offered as a hardware appliance, as software for on-premises or private cloud, and as a hosted cloud service. The range also includes UC clients for mobile, desktop and web, a contact centre module and a managed Cloud PBX solution. Customers can therefore choose between the cloud service and an installation on their own infrastructure.

The company is registered as Xiamen Yeastar Digital Technology Co., Ltd. in Xiamen, China, and its website names no parent company. Its privacy policy says personal information may be stored and processed in any country where Yeastar has offices or hosting servers, and that some processing is done by vendors whose locations are not named. The website mentions no EU data centre option, so the data location of a Yeastar cloud service cannot be confirmed from public information. The product is not open source. For a European organisation, the contract, the data location and the processing chain are the main points to check.

Why digital sovereignty matters with Yeastar

Yeastar is headquartered in CN, 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.

Yeastar 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.

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