Webroot Enterprise System Administrator Guide 5
Planning for Webroot Enterprise Deployment
If you plan to deploy Webroot Enterprise to 500 or fewer client workstations, you can use the base
configuration shown in Figure 1. If you are deploying to more than 500 client workstations, you
should review the information in this section to determine the best configuration and settings to
use.
Table 7 provides general configuration and database recommendations based on the number of
client workstations.
You may want to install additional distributor servers or company servers for two reasons:
• You have multiple sites and want to minimize bandwidth usage on WAN segments
between the sites. The normal communication between the client and the server is only
about 1 KB. Spy definition updates are typically 1 MB. A new Spy Sweeper client update
can be as large as 5.5 MB.
• You have a large number of clients relative to your server capabilities. Many things can
affect the performance of the server.
Deploying distributor servers reduces WAN bandwidth consumed when spy definitions or
software updates are delivered. Distributor servers receive copies of Spy Sweeper client and
definitions updates. For more information about how updates work, see “How Webroot Enterprise
Updates Work” on page 7.
In a configuration that uses distributor servers, the client workstations poll the company server. If
updates are available, the company server sends a randomized list of distributor servers to each
client workstation. The client workstation requests updates from the first distributor server on the
list. The distributor server sends the updates to the client workstation. If the distributor server is
not available, the client workstation sends its request to the next distributor server on the list. The
company server is always the last server on the list and will send the updates if no distributor
server is able to do so.
The figures that follow show some recommended configurations for typical deployments.
