  • My kids wouldn't go looking for those kinds of sites. Why do I need K9 Web Protection ?
    Even when they don't intend to, most children run into pornography, gambling and even predators on the Internet. Consider these statistics:
  • 70 percent of all 15-17 year-olds who have ever gone online have accidentally stumbled across pornography online, 23 percent "very" or "somewhat" often. One in five children ages 10-17 have received a sexual solicitation over the Internet. 43 percent of children said they do not have rules about Internet use in their homes.
  • 17 percent of parents believe their children are posting online profiles, as compared to 45 percent of children who report doing this. We don't want to sound alarmist, but the kinds of material available today on the Internet are nothing like the Playboy magazine of your childhood. The pornography is far more explicit and much of it promotes pedophilia or a connection between violence and sex.
  • Addictive gambling among teenagers is a growing problem, and many of them are learning to gamble online. Web filtering software can keep them from getting started. Social networking sites, such as Facebook or MySpace, can also pose a real danger for children. On these sites, teenagers and even pre-teens post personal information and photographs. These sites are a gold mine for predators.

What kind of computer do I need ?
K9 Web protection runs on all recent versions of Windows or Mac computers. K9 works no matter what Internet Service Provider delivers your Internet connection, and no matter which browser you use and supports all types of windows versions.

Can my kids turn it off ?
When you install the software on your computer, you will be asked to create a password. Only someone with the correct password can turn K9 off.

What kind of computer do I need ?

A "Block" Web page is displayed that tells you that this site is not permitted by your filtering software. If you want, you can also set K9 up so that Zander, the K9 Watch Dog, will bark. (This feature is nifty for parents. If you hear Zander barking, you can be pretty sure your kid has just clicked on a site that's a no-no.)

How does K9 Work ?

We maintain a database of Web sites that contain pornography, hate speech, violence, gambling and more than 55 other categories. When a computer user tries to go to a site that's in a category you want blocked, the "prohibited" screen appears, and Zander the K9 Watch Dog barks. (You can turn off the bark.) If a user tries to go to a Web site that the database hasn't seen before, it scans the content of the site for inappropriate material, and then either permits or prohibits the site (we call this process DRTR -- Dynamic Real-Time Rating). This happens so quickly that the user doesn't realize its happening. New prohibited Web sites are added to the database.

What's the difference between K9 and other filtering software ?

One difference between K9 and many other filtering solutions is that K9 is Internet-provider-independent and browser-independent. It will run on any Windows or Mac computer, no matter what Internet Service Provider delivers your Internet connection. It also works with any Internet browser.

Another difference is that K9 uses a commercial-grade filtering solution – it's a combination of a central database and dynamic page-rating technology that has been tested against the biggest players in the business, and come up on top. We see anywhere from 250 to 500 million rating requests every day. That's a lot of Internet visibility. The result is that you get the benefits of a serious solution in an easy-to-use package. Another difference is that K9 doesn't have to be "trained." You don't have to teach it which kinds of Web sites you want to block. It starts working as soon as you install it.
