Technical hosting signal
Independently established via a DNS/network lookup (not information from the vendor itself). This shows which network currently serves this vendor's website — often a CDN — so it does not necessarily reflect where the actual service or data is hosted.

Sovereignty profile of Pillar Security
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 outside the EU (IL) | 50 |
|---|---|---|
| Data residency (DRS) | No EU hosting (US, IL) | 100 |
| Cryptographic key sovereignty (CKS) | Key management with a non-European vendor | 60 |
| Platform lock-in (PLS) | Closed source: switching requires data migration | 60 |
| Source & runtime sovereignty (SRS) | Closed source, runtime with the vendor | 70 |
| Average | 68 |
Why digital sovereignty matters with Pillar Security
Pillar Security is headquartered in IL, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.
Pillar Security hosts data outside the EU (US, IL). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and drives the data residency score up.
Pillar Security 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 Pillar Security together with your other vendors and gives a total score, a heatmap and the main risk drivers.
