This feature uses Amazon Bedrock models that leverage Cross-Region Inference (CRIS), which automatically selects the optimal Amazon Web Services Region within your geography to process the investigation analysis and generate the investigation report. This maximizes available compute resources, model availability, and delivers the best customer experience. Your data remains stored only in the Region where the investigation request originates, however, investigation data and summary results may be processed outside that Region. All data is transmitted encrypted across Amazon's secure network. For more information, see GuardDuty Investigation.
