          Event Bus Data

          Event Bus Data

          Protect event messages and Change Data Capture (CDC) events at rest. The event bus may store event and CDC data in temporary files as it flows through integrations and real-time processes. Turning on Event Bus Data encryption ensures that event bus data in these temporary storage locations is fully encrypted.

          Required Editions

          Available in both Lightning Experience and Salesforce Classic (not available in all orgs).
          Available in: Enterprise, Performance, Unlimited and Developer Editions. Requires purchasing Salesforce Shield or Shield Platform Encryption.
          Note
          Note This page is about Shield Platform Encryption, not Classic Encryption. What's the difference?

          When enabled in a Shield Encryption org, event messages are encrypted using a dedicated event bus tenant secret. These encrypted messages are then stored in the event bus for a limited duration (typically up to 3 days for high-volume events, or 1 day for standard-volume). Messages are automatically decrypted before delivery to subscribed clients over a secure HTTPS/TLS channel.

          Change Data Capture provides near-real-time changes of Salesforce records, so you can synchronize corresponding records in an external data store. If a Salesforce record field is encrypted with Shield Platform Encryption, changes to encrypted field values generate change events.

          When you use Event Bus encryption when Database Encryption is on, the Event Bus data encryption happens first using its own tenant secret.
