Stela is hosted in the Microsoft Azure cloud in Western Europe. Each client’s data is stored in separate databases, with the option of a dedicated instance.

Passwords and devices
Each organisation configures password expiry and history. The public portal records known devices and blocks access by IP address after failed attempts.
Permissions and auditing
Granular roles and permissions, event-specific profiles and private records limit who can see each item of data. An audit log records changes field by field, including who made them and when.
Consent and unsubscribing from communications
Stela records consent or opt-outs by person and email, and provides a public option to unsubscribe from communications.
