Unbiased eTesting Labs report commissioned by DOJ
In this original and completely independent study (PDF, 232 KB) done for the U.S. Department of Justice, N2H2 was found to have a "Correct Blocking Ratio" of 98%. Unlike a later eTesting Labs study (paid for by another filtering company who set the "ground-rules" and elected to not include N2H2) this original study is the most honest comparison of all major filtering providers.

Report in prestigious journal again confirms N2H2's effectiveness
In December 2002 the Journal for the American Medical Association published a Kaiser Foundation study (PDF, 479 KB) on the effectiveness of all the major filtering products. Once again the conclusion was "N2H2 was the best at blocking pornography"! N2H2 also rated near the top of this study in recognizing and allowing access to useful medical information that can sometimes be blocked by less-effective filtering products.

The best filters have the best lists
Why is list quality so important? Every filter uses a database, or list, of URLs that are rated and categorized under headings such as "Porn", "Hate", "Sports", "Entertainment" etc. The filter uses this list to determine which sites the user can access. The better the quality of the list, the better the quality of the filtering provided.

A filtering list of lesser quality may still block plenty of sites, but it will also either let more inappropriate content through, block appropriate content, or do both. The result of using a less-effective filtering product is more requests for help from users, and worse, more access allowed to offensive and possibly dangerous content.

CIPA Compliant
As of July 1, 2001, The Children's Internet Protection Act (CIPA) requires that any school receiving federal E-rate funds must have a filtering solution in place. Using N2H2's fully CIPA compliant Internet filtering will help protect your E-rate funding status, while protecting your students by delivering a safer Web experience.

Links to pornography, graphic violence or illegal information are just a few examples of search results that are a far cry from the child's initial interest. Needless to say, the viewing of this material may be harmful and generate a lasting impression for some children. The prospect of an individual losing Internet privileges by unintentionally violating the library's Acceptable Use Policy, or worse, creating a potential liability issue are all compelling reasons to find a solution to this problem.

N2H2's Internet filtering solutions enable libraries to provide the most efficient and useful Internet service available to the community. N2H2's products deliver the flexibility to choose exactly which content to filter based on your library's Acceptable Use Policy. You also have the ability to offer different levels of filtering depending on the locations of your workstations.

Whether you are looking to filter 1 or 1000 workstations, N2H2 is the #1 selected solution to meet any size network. With millions of users worldwide, we are the largest server-based, educationally oriented filtering service on the market today.
