Find below some explanations regarding factors used for the licensing:

Number of users: concurrent, simultaneous, named or unnamed…

To the licencing, users are unnamed so the number of users can be assimilated to the number of connected computers. Also we distinguish concurrent users from simultaneous users. Concurrent users may be passive while simultaneous users are all active (generate traffic). To the licensing what counts is the number of simultaneous users. A standard license key allows you to run all available Security and Optimization modules on a unique machine. When you purchase CacheGuard OS you can either us it in forwarding mode or in reverse mode or in both modes at the same time.

The forwarding mode: web mode, capacity, implementation…

To implement CacheGuard OS in forwarding mode (to protect Web surfers) the most important factor is the total number of users. A capacity manager, integrated into the OS, tunes the appliance during the installation for a given number of users. The capacity manager takes into consideration that all users are not connected at the same time but at intermittent times. As a rule of thumb CacheGuard OS uses the ratio of 20% to define the number of simultaneous users. For instance a 100 user license allows you to protect 100 unnamed users, thus the appliance is tuned to run for 20 simultaneous users. Of course a burst of 100 connections will be supported as well for short period of time. In CacheGuard OS, the forwarding mode is called the “web” mode.

The reverse mode: rweb mode, capacity, implementation…

To implement CacheGuard OS in reverse mode (to protect Web servers) you should consider the number of simultaneous users (or Web connections) rather than the total number of users. The price for the reverse mode is the same as the forward mode. In CacheGuard OS, the reverse mode is called the “rweb” mode.

Blacklists service: subscription, basis…

Our blacklists are available as a download subscription service for a period of one year. The pricing is based on the number of users and is an independent subscription. The independent subscription is related to a unique public IP address and allows one download per day for each Blacklist category.
