Sovereignty profile of Insomnia
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) | Self-hostable: encryption keys under your own control | 10 |
| Platform lock-in (PLS) | Open source: low switching costs | 20 |
| Source & runtime sovereignty (SRS) | Source code auditable, forkable and self-hostable | 35 |
| Average | 51 |
Why digital sovereignty matters with Insomnia
Insomnia 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.
Insomnia 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.
Insomnia 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 Insomnia together with your other vendors and gives a total score, a heatmap and the main risk drivers.
