The first audience has been "family use". The intention was to remove objectionable content to the extent that a religious family can allow both children, teenagers and adults to ''benefit'' from the internet in much the same way it was thought that non-Jewish families ''benefited'' from the internet. In recent years, the entertainment, educational, economical (online shopping) and sociological (meeting new people) benefit to a religious family has been much questioned.
The second audience has been "professional use". Solutions were sought for people who are required and permitted to use the internet, either for their job, to perform research, or for jewish Jewish outreach. This category of people are generally people who are married and are preprared prepared to work with the non-religious public. This also includes ''baalei teshuvah'' who have taken on a a religious lifestyle by choice, and under Rabbinic guidance reach out to others and to encourage them to return. These individuals also often found themselves inundated with unwanted advertisements, objectionable imagery and opportunity for engage in social activities which would normally be discouraged in a religious household.
* '''Content-filtering'''- This technique involves looking for objectionable words or images within the content as it flows from the provider to the browser. The simplest schemes a simple word list. More complicated schemes do a statistical analysis of the page based on words used, methods of presentation and other artifacts of the webpage. These are the same schemes used to filter out spam email. One of the most interesting filters of this type was developed for the Islamic community. It works by doing image processing on each image (or anywhere on the computer screen) and identifies unwanted content by color, texture and shape. It has the advantage of allowing the user to access the entire internet, dynamically checking the content at the moment it is presented to the user. The disadvantage is that it tends to filter out only the most objectionable content, and may filter out legitimate content. The better the scheme, the more compute intensive it is, slowing response time. Many of these schemes require the content to be sent twice, doubling the bandwidth.
* '''DNS-filterningfiltering'''- Due to bandwidth issues, this was first scheme implemented by several "kosher internet" ISP services. TO BE CONTINUED
