Sovereignty profile of OpenDNS
How this vendor scores on the five dimensions of the Digital Sovereignty Heatmap: 0 is sovereign, 100 is high exposure. These are the same scores the assessment uses.
| Jurisdictional exposure (JES) | Headquartered in the US: CLOUD Act and FISA 702 | 90 |
|---|---|---|
| Data residency (DRS) | No EU hosting (US) | 100 |
| Cryptographic key sovereignty (CKS) | Key management with a non-European vendor | 80 |
| Platform lock-in (PLS) | Closed source: switching requires data migration | 60 |
| Source & runtime sovereignty (SRS) | Closed source, runtime with the vendor | 85 |
| Average | 83 |
Why digital sovereignty matters with OpenDNS
OpenDNS 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.
OpenDNS hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and drives the data residency score up.
OpenDNS 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 OpenDNS together with your other vendors and gives a total score, a heatmap and the main risk drivers.
