For Onyx cloud, all data is encrypted at rest with AES-256 encryption and TLS 1.3 for data in transition
As a set of containers, Onyx’s data persistence relies on data volumes. There are also data retention rules which can be configured in the admin panel expire data based on time.
If self-hosting, you are responsible for the encryption and locking down of the containers. Most cloud providers have these settings on by default, but you should confirm these security settings are enabled in your environment.
