Security in CrateDB

By default, CrateDB only allows access via the superuser crate from localhost. While this can be changed, it is highly discouraged, to keep the system as secure as possible.

SSL/TLS encryption can be enabled as documented. (The connections to CrateDB are not encrypted by default, since it requires valid x509 certificates).

Security in CrateDB Cloud

All the CrateDB Cloud services run via HTTPS or other encrypted protocols, following modern security best-practices. Customer clusters are only available via HTTPS and PostgreSQL's wire protocol with TLS encryption.
