What is the maximum number of Appliances within the same Security Group?

The maximum number of appliances within the same security group is 31. This is because a security group can have up to 31 Security Group Modules (SGMs) of the same or different models, and each SGM is an appliance that runs the Check Point software. A security group can span across multiple chassis, and each chassis can have up to 16 SGMs. However, the total number of SGMs in a security group cannot exceed 31.
