AWS – The Amazon S3 console now displays an external access summary for all your buckets

You can now view a global summary of policies that grant external access to buckets across your AWS account, directly from the Amazon S3 console. This summary lets you identify S3 buckets in any AWS Region that allow public access or access from other AWS accounts, without needing to inspect policies in each AWS Region individually.

The External access summary is powered by AWS IAM Access Analyzer and is available at no additional cost in the S3 console in all AWS Regions. Visit the S3 User Guide to learn more.
