This record was checked via the vendor's website and legal notice when it was added on September 20, 2026. Source links have been recorded per record since 20 September 2026.
Compliance evidence
The links below point to the vendor's own public documents. We only record what we found: a missing link means "not found publicly", not "not compliant".
No public compliance evidence has been recorded for this vendor yet. Do you know its DPA or subprocessor list? Something wrong? Suggest a correction
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 Weld
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 EU: European law applies | 0 |
|---|---|---|
| Data residency (DRS) | EU-only hosting | 0 |
| Cryptographic key sovereignty (CKS) | Key management with a European vendor | 40 |
| Platform lock-in (PLS) | Closed source: switching requires data migration | 60 |
| Source & runtime sovereignty (SRS) | Closed source, runtime with the vendor | 45 |
| Average | 29 |
Why digital sovereignty matters with Weld
Weld is headquartered in DK and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.
Data is hosted exclusively in the EU, so Weld scores best on data residency.
Weld 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 Weld together with your other vendors and gives a total score, a heatmap and the main risk drivers.
