Review: Amazon GuardDuty Malware Protection for S3

Amazon GuardDuty Malware Protection for S3 is designed to scan files for malware upon upload. However, it has limitations such as lack of scheduled, on-demand, or on-access scans, and basic mitigation capabilities with only tagging available. Reporting features are minimal, and integration with other AWS tools like EventBridge is necessary for additional functionality. The pricing model can scale significantly depending on the workload, and there are technical limitations including a maximum S3 object size of 5 GB. The service maturity score is 8.0, benefiting from its integration with the mature GuardDuty service.
