Internet filters--also known as content-control software, web filtering software or censorware--are a category of software designed to control the types of content that can be viewed on a computer network or standalone station. While the software can be used for multiple purposes, Internet filters are often designed to help you reduce the access your children have to pornography, explicit content and fraudulent or phishing websites on the Internet.
Function
Family-friendly Internet filters are designed to minimize exposure to potentially harmful content on the Internet. These Internet filters can block images, text and sometimes videos from appearing on your home, school or library computer. In addition to blocking content, filters can often block access to websites that attempt to collect personal data for illegal purposes. The Federal Bureau of Investigation recommends the use of parental control software such as Internet filters to help minimize your family's risk from online exploiters and child predators.
Features
Every Internet filter software program offers a slightly different mix of features for customization. Some filters allow the blocking of specific websites, types of content like pornography and activities such as instant messaging, emailing or web surfing. Advanced Internet filtering software can provide monitoring components that allow you to monitor online conversations, keystrokes and the website history from your children's online searching. Additional features can include social network reporting and filtering, port blocking, filter lists and predator blocking.
Options
Some Internet Service Providers (ISPs) offer Internet filtering software or controls as part of their service offerings. Net Nanny is one of the most established and trusted Internet blocking software packages.
Price
Internet filters range in price from free services to around $40 as of October 2010. Free filters tend to be based on an existing service such as your Internet connection or your Domain Name System (DNS). Software products may offer a free trial or money-back guarantee and promotions may lower the software cost.
Considerations
No Internet filter can block all unwanted images or activities, and routine monitoring of online activities is necessary to ensure your children are using the Internet as you deem appropriate. Services that can monitor online activities can help you review chat sessions, website activities and the interactions your children have with others. Internet filters cannot replace careful monitoring and review of your family's online risks and activities.
