Why digital sovereignty matters with Emissary-ingress
Emissary-ingress 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.
Emissary-ingress hosts data outside the EU (self-host). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and drives the data residency score up.
Emissary-ingress is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.
What this means for your organisation depends on your whole stack and context. The free assessment weighs Emissary-ingress together with your other vendors and gives a total score, a heatmap and the main risk drivers.
