According to its privacy information, personal data is transferred to the United States with safeguards that are not described in detail.

Why digital sovereignty matters with Welocalize

Welocalize 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.

Welocalize hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

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