Stopping cross-Region aggregation
If you don't want AWS Security Hub to aggregate data, you can delete your finding aggregator. Alternatively, you can
keep your finding aggregator but not link any AWS Regions to the aggregation Region by updating the existing aggregator
to the NO_REGIONS
linking mode.
To change your aggregation Region, you must delete your current finding aggregator and create a new one.
When you delete your finding aggregator, Security Hub stops aggregating data. It doesn't
remove any existing aggregated data from the aggregation Region.
Deleting the finding aggregator
(console)
You can delete your finding aggregator from the current aggregation Region only.
In Regions other than the aggregation Region, the Finding
aggregation panel on the Security Hub console displays a message that you must edit the
configuration in the aggregation Region. Choose this message to display a link to
switch to the aggregation Region.
