What do the last two digits of the 51XX appliance family indicate?

The last two digits of the 51XX appliance family signify the endpoint capacity of the appliance. This numerical designation indicates the maximum number of endpoints that the appliance can manage effectively. For example, if the last two digits are '30', it implies that the appliance can support up to 30 endpoints in its operational capacity. This specification is crucial for organizations to understand their needs regarding network security and endpoint management, as it helps in selecting the right appliance based on the size of the network and the number of devices that need to be monitored or managed.

Understanding the endpoint capacity allows administrators to plan for scalability and ensure that the chosen appliance aligns with the organization's demands, ensuring that security measures are adequately applied to all connected devices.
