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 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.
