Monitor more changes to permission sets and permission set groups using transaction security policies in Event Monitoring. These new transaction security policies enable you to block permission changes in permission sets and permission set groups that don’t comply with internal usage, compliance, or security policies. You can also send notifications to admins when changes don’t comply with those same policies.
Where: This change applies to Lightning Experience and Salesforce Classic in Enterprise, Performance, Unlimited, and Developer editions where Event Monitoring is enabled.
