Note
The aggregation Region is now called the home Region. Some Security Hub API operations still use the older term aggregation Region.
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 home Region by updating the existing aggregator
to the NO_REGIONS linking mode.
To change your home 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 home Region.
Deleting the finding aggregator
(console)
You can delete your finding aggregator from the current home Region only.
In Regions other than the home Region, the Finding aggregation panel on the Security Hub console displays a message that you must edit the configuration in the home Region. Choose this message to display a link to switch to the home Region.
To stop cross-Region aggregation (console)
Open the AWS Security Hub console at https://console.aws.amazon.com/securityhub/
