On 12 February 2024, changes will be made to how Stax-managed Security Hub is configured. This update will align the Stax-managed Security Hub service with the new AWS Security Hub capability announced by AWS. 

After the change, Stax will only enable and configure cross-region aggregation for Security Hub in regions that are explicitly enabled in Stax-managed Security Hub.

Previously, Stax enabled Security Hub and configured cross-region aggregation for every available region in every account. While supported Security Hub standards and controls were only enabled in the regions explicitly enabled in Stax-managed Security Hub.

If you have already enabled Stax-managed Security Hub and would like the service to continue to be enabled with cross-region aggregation in every available region, ensure that you update your current Stax-managed Security Hub configuration by toggling on the "All Regions" option or selecting individual AWS regions from the list.

To avoid interruption to service,  update your Stax-managed Security Hub configuration before 12 February 2024. If no action is taken, Stax will only enable and aggregate Security Hub in regions enabled in the Stax-managed Security Hub service.
