Description:


Typically, WebDefender will be installed in your DMZ or LAN and accepts all outbound HTTP traffic. Web pages are cached, then inspected.

 

The WebDefender database is automatically updated each day with new, websites, so that inspection is timely and current. You have the ability to over-ride (White-List) and add-to (Black-List) these automatic updates.

 

Web caching enhances the web browsing experience by caching commonly accessed web content and serving subsequent requests for the same content locally rather than requesting it from the actual web site.

  1. Host-based Denial of Service Prevention

  2. Web-Based Administration Interface

  4. User Tracking via Login & Password

  5. User Authentication via LDAP or user database

Filtering Process:

  1. Checks the website to see if it is a banned site or not. Automatic daily updates are made to the database. Blacklisting and White-listing of websites is possible.

  2. Checks to see if specific URL’s are banned. Daily updates are made to the database. Blacklisting and White-listing of URL’s is possible.

  3. Keywords and Expressions are checked to see if they should be banned. There are 40 categories and user-definable categories for management controls. Black-listing and White-listing is possible.

  4. Web pages of certain type can be blocked. User-defined Blacklist is maintained.
