Web Filtering
The use of the Internet has become a normal and powerful tool, as a useful form of technology. However businesses have identified the need to create policies in relation to its usage within the workplace. It is estimated within the workplace that between 30 – 40% of overall Internet usage is not related to the actual operations of the company. We can configure a web filter to enforce internet usage by blocking access to websites and internet applications that are not related to work activities. In addition to this it easily and completely eliminates spyware and other forms of malware from your network.


Some examples of these configurations include:

  • Block applications that access the internet, including instant messaging, music services, and software update utilities
  • Restricting access to job board Web sites to only the Human Resources group
  • Defining separate policies for office users and reception users at a club
  • Enabling compliance officers unrestricted access to the web for investigation
  • Providing external instant messaging (e.g., AIM) access only to specific users or groups
  • Restricting personal web browsing to non-working hours
