Block all websites except Whitelist

Content blocking is the most necessary and important function for both parental control and employee monitoring software. There are two ways how you can block unwanted content with whitelist and blacklist of websites.

Whitelist allows you to automatically block all website that is not in your list of allowed websites. This requires preparation at the beginning when you need to add websites to the whitelist, but guarantees maximum protection and reduces your risks to minimum. Whitelist mode is ideal for children under 10-11 years, because this is the most reliable way of controlling what websites can be accessed and what can't. Whitelist also can be used to completely turn off all traffic on your computer. Unfortunately whitelist can not be set up with the Hosts file or with browser settings.

Blacklist, on the contrary, blocks websites listed in the list and allows all others. You can add websites or keywords that determine whether a website is trusted or not. This way of filtering content is more suitable for older children, whose parents want to protect their children without giving them the feeling that they are “over-controlled”. This can not guarantee 100 % safety, so in case of using blacklist, we recommend monitoring website activity to detect inappropriate content that was not blocked and then add such websites to blacklist.

If you think about using reliable website filter with whitelist mode for your home or office, HT Parental Controls and HT Employee Monitor can offer clues.
