It is recommended to also enable Automated Assessments to ensure summaries include the most recent data from your AWS environments
Email summaries provide a weekly overview of your AWS accounts' security status, including top failed assessment checks, new rules with failed resources, and a summary of AWS security services. In addition, the summary includes an overview of the account spend and top services by spend.
Example Summary Email
Email Summaries can be enabled/disabled under Dashboard > User Settings. By default, the emails are sent to the email address associated with the user profile, and additional emails can be added under the Additional Email Addresses field.
Email summaries can be enabled for accounts covered by an Ongoing Protection License
