Filtering in a Network with Citrix
®
Server Users
If your network includes some users who access the internet via a Citrix®
server, and others who access the internet through another gateway (firewall,
caching appliance, or proxy server), you must install two complete instances
of Websense software:
 One instance of Websense software choosing the Citrix integration, to
filter Citrix users. Follow the instructions in the Installation Guide for use
with Integrated Citrix
®
Servers.
 Another, separate instance of Websense software, to filter the non-Citrix
users. This instance of Websense software can be integrated with the other
gateway (firewall, caching appliance, or proxy server), or it can be the
Websense Stand-Alone Edition. To install this Websense instance, follow
the instructions in the Websense Enterprise and Web Security Suite
Installation Guide for the integration product you are using, or for the
Stand-Alone Edition.
System Requirements
Websense software can be installed on machines with Windows, Solaris, and
Linux operating systems (see the Deployment Guide for supported versions).
Not all Websense components are supported on all three types of operating
system. However, you can install Websense components on machines with
different operating systems, and they will be able to communicate with one
another. For example, an instance of Websense Manager installed on a
Windows machine can configure a Policy Server installed on a Windows,
Solaris, or Linux machine. For a list of supported operating systems for each
Websense Enterprise and Web Security Suite component, see the Deployment
Guide for Websense Enterprise and Web Security Suite.
Such factors as network size, network configuration, and internet traffic
volume can affect the ability of Websense software to filter internet requests.
For hardware recommendations for your network, see the Deployment Guide
for Websense Enterprise and Web Security Suite.
For a complete list of system requirements for installation of Websense
Enterprise and Web Security Suite components in your network, see the
Deployment Guide for Websense Enterprise and Web Security Suite. This
section contains system requirements specific to your integration product.
