S4F’s flagship product is still actively supported today and used by tens of thousands of households. Using innovative Windows filtering technology, the FilterPak works efficiently to ensure detrimental sites do not reach your computer.
The FilterPak is downloadable software that provides Internet filtering for home. It works with your current Internet connection and communicates with Centipede Networks’ list servers using a small software program called a “thin-client”. Upon installation of the filtering, this “thin-client” is placed on your computer, where it operates in the background of the system, much like a virus protection program.
The “thin-client” works in concert with the list server by forcing all URL requests to compare against the blocked site list before allowing or disallowing the end-user to view the site. Since this check is simply the comparison of strings of text, it takes a mere fraction of a second to complete.
