Internet Filter

Net Nanny® is the #1-Rated Family Internet Filter Trusted by Parents

Did you know that according to the Kaiser Family Foundation, roughly 70% of children are accidentally exposed to pornography each year? With kids having more access to smartphones and technology at home and at school, Internet filtering software is only increasing in importance. With Net Nanny's real-time content filter, parents now have visibility and control over their child’s online activity with easy-to-use parental controls.

Parental Control Software That Goes Beyond Whitelists

Net Nanny® takes parental control software beyond what traditional whitelists and blacklists of websites are able to provide by allowing parents the ability to adapt to their child’s online activity on a content category level. A whitelist is a list of websites with acceptable content, while a blacklist provides a list of websites that should be blocked due to adult or inappropriate content.

Many whitelists and blacklists available online quickly become obsolete, since there are countless new websites added to the Internet every day. But with Net Nanny’s advanced Internet filter, websites are filtered each time a page is loaded in real-time, so you can protect your family’s online activity instantly. Net Nanny® also allows parents to create a blacklist of sites you would not like kids to be able to visit.

Content Filtering Technology That Keeps Up with the Internet

Net Nanny® uses technology to review the content of each website your child browses, in real-time, without slowing down their computer or mobile device. In the time it takes you to enter a URL and hit “enter,” our advanced filtering technology evaluates the website content in the context in which it is used.

Net Nanny® relies on state-of-the art technology to review the content of any website visited – each time you browse and in real-time. Why is that important? The Internet changes constantly as websites are updated daily, and thousands of new user-generated sites are added worldwide. Families and accountable individuals deserve an adult content filter that can keep up with these constant changes.

Our advanced filtering technology is even able to evaluate website content in the context in which it is used. For example, Net Nanny’s Internet filter can distinguish between the use of the term “breast” when it's used in a medical or clinical context (i.e., breast cancer) or when used to discuss cooking (i.e., chicken breast) vs. when used in an adult or sexual context. Net Nanny® detects the contextual usage of words and will either allow or block websites based on the preferences customized for each individual user.

Net Nanny's content filtering software also uses cutting edge technology to review website advertisements and other frequently changing content — each time the webpage is refreshed. Net Nanny® reviews website content instantaneously and all webpages are categorized according to the content that is displayed at the time each page loads for viewing.

How Net Nanny’s Internet Filter Works

With Net Nanny®, you can be sure you have the best protection available to shield your kids from online dangers. You’ll have complete control over the settings that will guide the monitoring, and appropriate filtering, of your kids’ devices.

Unlike most Internet filters that block entire websites, Net Nanny’s award-winning technology analyzes every web page they visit, plus content in certain apps. Our advanced Internet filter then determines in real-time if it is safe for your child, based on the category guidelines that you pre-determine.

Whenever Net Nanny® determines there might be an unsafe situation for your child such as hate speech, pornography, or bullying, you will be alerted immediately. Net Nanny’s Internet filtering technology checks each web page your child visits, as they search and surf, and either allows, alerts, or blocks based upon the settings you can customize for each user. With Net Nanny’s alerts and reporting, parents have the flexibility to determine which types of content is appropriate for each user in your family.

  • Allow: This setting lets users access the websites you determine as safe.
  • Alert: This setting will not block this website from users, but you will receive an alert that it was accessed and viewed.
  • Block: This setting allows you to block this website from being viewed.

This makes Net Nanny® the perfect tool for analyzing today’s Internet, which is dominated by constantly changing content. Net Nanny® is the only product that can protect your child – at home, or at school, for apps or on websites – you can know they are safe with the best Internet filter available.
