| Cryptographic key sovereignty (CKS) | Self-hostable: encryption keys under your own control | 10 |

Why digital sovereignty matters with Chroma
Chroma is headquartered in US, 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.
Chroma hosts data in EU, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.
Chroma 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 Chroma together with your other vendors and gives a total score, a heatmap and the main risk drivers.

- Elastic↗
Elastic (Elastic N.V.), headquartered at Keizersgracht 281, Amsterdam, Netherlands, develops Elasticsearch, the widely used distributed search and analytics engine, alongside Kibana and Logstash (the "ELK stack"). Since September 2024 Elasticsearch and Kibana source code is triple-licensed under AGPLv3, SSPL, and the Elastic License v2, with AGPLv3 being OSI-approved, restoring genuine open-source status after the 2021 licensing dispute. It can be self-hosted, run via Elastic Cloud with selectable EU data-center regions, or deployed via other providers, giving strong flexibility for EU sovereignty requirements.
