Net Nanny® is one of the most effective and best website blockers available for families.
With Net Nanny’s website blocking software, you can keep your family’s online experience safer and tailor individual settings to block websites and block categories of web content based on each of your family member’s needs. Net Nanny® allows for specific websites to be blocked or allowed, based on the settings you choose, so parents can set age-appropriate safeguards for their children and themselves.
Why Blocklists Aren't Enough?
With thousands of new websites created every day, it’s hard to keep track of which ones are appropriate for kids. Many families turn to blocklists, or lists of unsafe or mature websites, to keep their children’s internet experiences safer. Blocklist filtering is a long-established and widely used form of website blocking. When a user attempts to go to a website, the URL for that website is compared to a known list of inappropriate sites. If the website is on the list, that site is blocked.
However, blocklists are not able to be updated as quickly as new unsafe websites are created or account for user-generated content that frequently changes. If your family is relying on outdated blocklists to keep your kids safer online, there is a high chance of exposure to adult content, pornography or dangerous websites. In this case, blocklists are prone to under-blocking, since their list of websites is likely out of date and can’t keep up with user-generated content. However, blocklists can also over-block by prohibiting access to entire websites, when singular pages on the website may be perfectly safe.
Unlike most Internet filters that block entire websites, the award-winning Net Nanny® web filtering technology analyzes every webpage your child visits, plus content in certain apps. Our content filter then instantly determines if the content on that webpage is safe for your child to view, based on the category guidelines and website restrictions that you pre-determine.
Because Net Nanny® relies on real-time Internet filtering, your family is safer from inappropriate or unwanted websites. Parents using Net Nanny® still have the option of blocking websites individually and can tailor lists of allowed and blocked websites for each user on their account. Additionally, parents can choose from 14 different categories to allow, alert or block for their child.


How Net Nanny® Website Blocking Works
Net Nanny’s filtering technology scans websites for inappropriate content in real time. Unlike other software, Net Nanny® doesn’t use cookie cutter website block lists – instead, our internet filtering and website blocking software scans the content on each webpage and blocks it based on the categories that you choose to filter.
Net Nanny® parental control software scans websites as you’re surfing, searching and scrolling in real-time, blocking websites that contain material you’ve flagged in the settings. With our parental controls, you can help protect your family with one of the best internet filters and website blockers out there.
Net Nanny’s internet filter and website blocker utilizes AI-based natural language filtering, which is not only able to detect specific keywords on a webpage but can also determine the context of that word relative to the content on the page. For instance, if the word “breast” is detected on a webpage, Net Nanny® will scan the rest of the page to determine if this word is used in the context of cooking (i.e. chicken breast) or an inappropriate context, and block accordingly.
