| Best for | Teams running Kafka plus databases across clouds | Developer teams wanting Postgres plus auth, APIs, and storage |
| Who it's not for | Anyone needing just one small database | Non-technical teams wanting a no-code database |
| Privacy | Active security program . TLS enforcement, DPA, compliance pages and published CVE advisories; no breaches reported in reviewed sources.⁹ | Strong on paper: SOC 2 Type 2, ISO 27001, HIPAA (with BAA), AES-256 at rest, TLS in transit, regular pen tests.13 |
