Customer Metadata Boundary
As part of the Data Localization Suite, the Customer Metadata Boundary (CMB) ensures that any traffic metadata that identifies a customer’s end user (that is, contains that customer’s Account ID) stays in the EU or in the US, depending on the region the customer selects. That means, for example, that if a customer selects the EU Customer Metadata Boundary, metadata will only be sent to our core data center in the EU and not our core data center in the US.
