The MX Security Appliance has multiple license editions: Enterprise and Advanced Security. Please note that the MX licensing edition is uniform across the organisation. For example, you can have all 25 appliances using Enterprise Edition or Advanced Security Edition, but you cannot have 20 appliances using one edition and 5 using the other edition. If you wish to use Enterprise Edition for some appliances and Advanced Security Edition for other appliances, you need to create two organisations, one for your appliances with the Enterprise Edition, and another for the appliances with the Advanced Security Edition.
