Zyxel Nebula: sovereignty score and 8 European alternatives

Zyxel Nebula is Zyxel's cloud platform for managing network equipment centrally. Through the Nebula Control Center you configure, monitor and update Zyxel access points, switches, firewalls and 4G/5G routers in one place, including across many sites. The platform offers a mobile app, zero-touch provisioning, multi-tenant management for managed service providers and an open API. Nebula is delivered as a cloud service.

Zyxel is a Taiwanese manufacturer headquartered in Hsinchu Science Park; no parent company in another country is known. According to Zyxel's support documentation, Nebula data is stored in AWS data centres in Ireland. Because the infrastructure runs on AWS, a US provider, US jurisdiction over the underlying infrastructure remains a point of attention. For a European organisation this is a Taiwanese vendor with data storage in the EU; it is sensible to review the data processing agreement and the list of sub-processors.

Why digital sovereignty matters with Zyxel Nebula

Zyxel Nebula is headquartered in TW, 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.

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

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