Security and legal teams determine subscriber data available to EMEA teams should NOT be available...

To ensure subscriber data is appropriately segregated between the EMEA and AMER teams, the Marketing Cloud admin should separate regions into different business units and apply Subscriber Filters. This setup allows for distinct data management and access controls per region, aligning with security and legal requirements. By configuring business units specific to each region, the admin can effectively control data visibility and operations within those regional contexts.
