To enable Amazon GuardDuty on all the accounts you need to send an invitation to all members that you wish to activate the GuardDuty on and when once the invitation is sent then you can use the AWS CloudFormation Stackset template to enable the Amazon GuardDuty in all the accounts. Then you can choose the “Enable Amazon GuardDuty” template by going to the CloudFormation Console and select a new stackset tab.
