Scout Suite is an open-source multi-cloud security-auditing tool, which supports services such as AWS, Azure, and GCP. It is designed to provide security insights and evaluate the configuration of cloud assets, making it suitable for the analyst's needs to assess the AWS cloud environment. Scout Suite offers an advantage over other tools in its ability to display results in a user-friendly manner, which helps in identifying misconfigurations and ensuring compliance with industry best practices. The other listed tools do not provide the same level of cloud-specific auditing focused on best practices and compliance.
