Guard Duty with Security Hub

Question

trying to understand relationship between security hub and guard duty in aws organisation sub account

If GuardDuty is enabled on organisation member account B and security hub is enabled on organisation master/delegated admin account A 
than will the master account A recieve findings from account B even if we don't enable guard duty in master account?

If Security Hub *and* GuardDuty are enabled in the *same* account then Security Hub **will** receive the GD findings for *that* account and then send all findings to Security Hub in the delegated admin account for that region. Enabling GuardDuty on all accounts and in all regions is recommended best practice however - there is no cost if there are no workloads or activity in that account and if something *WAS* to happen then at least you would know about it. In addition it make it so much easier to manage and view all GD findings in a single account. Is there a reason for not enabling GD in your management/delegated admin account? (Note: we recommend making the delegated admin account the same for ALL security services like GD, SH, Inspector, Macie, Detective etc)

Yes, I have tried it in my environment.

You can receive findings from member account B without enabling GaurdDuty on management/delegated admin account A.
