S4F FilterPak is an affordable, effective solution to the problem of pornography on the internet. You and your family may enjoy the internet without the fear of accidentally stumbling on bad sites, or being tempted to see what's just "a click away". S4F works with your existing ISP account to keep pornographic content from loading on your computer. The filtering works by checking the site against our database of blocked sites, then allowing or blocking the request. Once a site is allowed, your computer retrieves the site through your own ISP connection (without having to route it back through our servers). This means that S4F is the perfect solution for all users, even those with high-speed broadband connections such as ADSL, DSL, and cable modems.

WiseChoice.Net is a windows sub-system based system. All filtering takes place on our servers, not on your computer. Every time you type in an Internet address, or click on a link to an Internet address, or type in a word to search for, the address or word you requested is routed to our computers where it is checked against our block list. If your request is not on our list you proceed as normal to the site you requested. If your request is on our list, you get a message stating that the site you requested has been blocked along with the explanation. Since we have lightning-speed computers and the fastest possible connection to the Internet, the whole process of checking your request takes less than a second once it reaches the Internet. WiseChoice.Net

In addition to filtering software, there are "filtered ISPs" which provide protection as long as you are using them for the internet access.. For more information on these, search for filtered ISPs, or investigate some from the list below:

"Not knowing is the crime!"

A familiar phrase after the problem. Regardless if your a parent, librarian or designated administrator you need to know what is happening. WebBlock gives you the capability to monitor activity from any computer, and you have WebBlock personnel backing you up by monitoring the sites visited and applying a rating, if missing.

Knowing what data is browsed allows you to provide better service, gives you on-demand feedback and allows you to keep ahead of future problems.
