CMS supports an optional pooled licensing model that allows user licenses to be centralized on the CMS and available to the managed appliances. Individual VPN appliances no longer need their own license. Customers with appliances that are globally distributed can benefit from the fluctuating demands for user licenses due to time differences. Central user licenses are available to managed appliances where user demands have peaked when license demand has fallen in other regions due to off-work/night hours. For more information, refer to Central User Licensing.
