 About 70% of organizations transfer unfiltered information via instant messaging software.
 In large organizations, around 75% of the attacks are performed within the network, most without user knowledge.
 Services exist that require filtering, which run on Port 80. For example: P2P File Sharing.
 Various services in a network cause heavy load. For example: 44% of the users watch streaming media.
 There is a need to filter access to undesirable information sources on the internet, some of which are dangerous to information protection.

The Websense organizational protection solution includes a central server, which can be installed as a separate server or under top proxy servers, as well as under most existing Firewall solutions. The server receives real-time and daily updates from Websense, which include new websites, protocols and applications, divided into categories according to subject.

The different modules that make up the Websense system:
URL Filtering
The Websense content filtering solution is based on an ever increasing database that contains over 10,000,000 websites, whereby this database is automatically updated daily with all the new websites that have been added to the network (over 5000 websites per day).
The websites are divided into more than 90 categories and sub-categories in over 50 languages. Based on the division into categories, the network manager, security manager or another management authority can block access to certain groups of users. As a result of adhering to content filtering policy, expense saving in efficient use of existing bandwidth and saving in expensive work hours is significant.
Monitoring and restriction can be performed according to category and sub-category, user groups and individual users, key words, specific URL, bandwidth capacity, file type, protocols, allocating quotas to all users for certain categories, and more.
