8x8: sovereignty score and 8 European alternatives

8x8 is a provider of cloud communications and customer experience software for businesses. Its offering covers unified communications (8x8 Work with telephony, messaging and video meetings, plus Microsoft Teams integrations), an omnichannel contact centre with AI support for agents and workforce engagement, and a CPaaS with APIs for SMS, voice and video. 8x8 also offers AI tools for building AI agents and for routing customers. All services are delivered as a cloud service (SaaS and APIs). The company also owns the Jitsi brand.

8x8 is headquartered in Campbell, California, is listed on Nasdaq and falls under US jurisdiction, including the CLOUD Act. In 2025 it opened a data centre in France; according to the company, this supports French and European data-residency requirements, although it is not stated which services run there. The product is proprietary and not open source. A European organisation therefore needs to check, service by service, where 8x8 stores data and which jurisdiction applies to the provider.

Why digital sovereignty matters with 8x8

8x8 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.

8x8 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.

8x8 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 8x8 together with your other vendors and gives a total score, a heatmap and the main risk drivers.
