Compliance Accelerator lets you organize monitored employees into departments that reflect the structure of your company. For example, you can create departments that are called "Marketing", "Sales", and "Engineering". Then you can add the employees that you want to monitor to the appropriate departments.
After you have set up multiple departments, you can group them into partitions. This facility lets you restrict the scope of searches to items to and from monitored employees in departments in the same partition. If you do not define any partitions, the searches that you initiate in one department can include the items of employees in other departments.
