Filtering Service
Deployment and Installation Center | Web Security Solutions | Version 7.7.x
Applies to:                                         
*
Web Filter, Web Security, and Web Security Gateway (Anywhere), v7.7.x
Filtering Service works with Network Agent, Content Gateway, or a third-party integration product to provide Internet filtering. When a user requests a site, Filtering Service receives the request and determines which policy applies.
*
Filtering Service must be running for Internet requests to be filtered and logged.
*
Each Filtering Service instance downloads its own copy of the Websense Master Database.
In a Websense appliance-based deployment, Filtering Service is installed on any Web Security appliance.
In a software-based deployment, Filtering Service is typically installed on the same machine as Policy Server. Large or distributed environments may include multiple Filtering Service instances.
Special considerations
During a custom installation, to install Filtering Service, Policy Server must already be installed either on this machine or another machine in the network. If Policy Server is not installed already, you can select it to be installed at the same time as Filtering Service.
 
* 
Note 
The following three components must be installed in this order (and before any other components):
1.
Policy Broker
2.
Policy Server
3.
Filtering Service
If you select all three to be installed at the same time, they are installed in the correct order. After these components, all other Websense components can be installed in any order.
Depending on the size of the network or volume of Internet traffic, multiple Filtering Service instances may be needed. It is a best practice to have a maximum of ten Filtering Services per Policy Server.
Filtering Service must be installed before Network Agent, Filtering Plug-in, and Linking Service.
