A client-side filter is a program you purchase to install on your home computer. Many companies make these products, and the features vary. Access can be denied to a list of restricted sites. Sites can be blocked by the presence of certain words. Filters are not a substitute for Internet-use ground rules, or for parents talking with their children about safety on the Internet.
Filters can have leakage, and allow objectionable material to slip through unblocked.
You may also look for other features. Some programs block the input of personal information. For instance, if your child types in your home address, the program would block that string of characters and not put that information out on the web. Start by asking questions about your own needs and the ability of filtering programs to meet those needs. A list of Web site resources is included in this brochure.
