W3Control - Internet Productivity Analysis and Internet Filtering Software

W3Filter
Enterprise Internet filtering software that allows a company to enforce an Internet acceptable use policy. The
W3Control database includes 60 categories (ie. Sex, Hate Speech) which are used to "allow" or "deny" access. In addition to the supplied W3Control database, an unlimited number of user defined databases may be created. Filtering rules can be defined to allow or deny W3Control categories or user defined databases. Rules can always be active or only enforced on specific days of the week and time of day. Users may be grouped to allow further granularity of rules. W3Filter works with most major firewall vendors and proxy servers. W3Filter can also operate as a stand-alone proxy server.

W3Control Filter provides the power and flexibility to enforce Internet policies through filtration to the entire enterprise, workgroups and individual workstations:

  • Automated log rolling
  • Monitoring and reporting of Internet usage with W3Thermo

  • Scalable to support tens of thousands of requests per second through multiple processors, simultaneous requests per process, multiple processes, caching and balance loading across multiple servers.
  • Proxy server included or may work with existing proxies and firewalls
  • Workstation software not required, browser that supports a proxy necessary.

Workstations require only a web browser such as Netscape or Internet Explorer that support a proxy server. The W3Control Filter server sits between the user and the Internet monitoring and filtering all web traffic. If a user attempts to access a site or URL that is restricted, W3Control will pass an HTML message back to the user's browser indicating that access has been denied.

The W3Control server supports:

  • up to 16 separate network interfaces
  • multiple processors
  • multiple processes
  • multi-threaded processes
  • balance loading between multiple servers

This robust processing enables the product to scale from several hundred users to tens of thousands of users.

The network interfaces may be configured as "Internal" and "External". An internal interface always listens for proxy requests. When an internal proxy request is received, the request is evaluated against the filtering rules and processed accordingly. External interfaces do not listen for proxy requests but, rather, are typically assigned to interfaces directly connected to the Internet and not the internal network.
