The next type of web filtering is called network-based web filtering.
While these types of web filters are not yet widely available, they may be in the future. Virgin Media for example, is an ISP that used this type of web filtering to block the Pirate Bay from subscriber access. Typically found in countries who censor content on the web, these types of web filters are gradually making their way to countries around the world. C ontent-limited ISPsĬontent-limited ISPs are internet service providers who block off specified websites from all who subscribe to the ISP’s service. These types of web filters can also be easily circumvented by those who have administrative privileges since these types of web filters are often directly installed on the device and not controlled by a central program. While these types of web filters may be ideal for a small business, larger businesses may not want to deal with the hassle of setting up this type of web filter on more than a few computers.

Search engine filters can also be easily circumvented if the user knows the URL of the site they are trying to access or if they use another search engine that does not have a similar filter. Google and Bing have Safe Search options for those who want to filter out inappropriate content in their search results.īoth of these search engines have Safe Search on as a default, but one does not need administrative privileges to turn these filters off. Some search engines have this feature built in to their user interface. Search engine types of filters sift out unsuitable content from the results a user sees when looking up information through a search engine. So if you decided to use Firefox when you’ve got the Kardashian Filter installed on Chrome, you will still be susceptible to headlines, copy and imagery that references the celebrity family. By doing so, the user renders the filter on the initial browser useless. The main downfall of these types of web filters is that users can circumvent them by switching web browsers. Some popular options for browser-based filtering include Blocksi, a program available for Google Chrome and Mozilla Firefox which blocks pre-defined content from user access.Īnother popular (and humorous) web filter available for Chrome is the Kardashian Filter, which removes all content related to the Kardashian family from user view.
