Technical Tip: FortiClient EMS Cloud - Multitenancy

• On EMS Cloud, there is no 'Manage Multiple Customer Sites' option in System Settings -> EMS Settings, like there is on EMS On-premise deployments. (Only one FortiClient EMS Cloud instance per FortiCloud account).
• Multitenancy on EMS Cloud is obtained with the use of FortiCloud Organizational Units.

• To create FortiCloud Organizational Units, a FortiCloud Premium account is required.
• An individual Organizational Unit should be created for every managed EMS site.
• An individual EMS Cloud instance is deployed for each Organizational Unit.
• A separate license is required for every EMS Cloud instance.
