The K-9 program is designed to effectively protect computers from immoral, forbidden or psychologically traumatic Internet content. The program uses a web content filtering system for more than 55 categories. The filter works in local service mode, the program uses Blue Coat's filtering database. The web filter contains a rating of more than 15 million websites containing billions of web pages organized in the most suitable and useful categories. To ensure accuracy, each site in the Web Filter database is listed in several suitable thematic categories.

A web filter has an average coverage of over 94% of the requested sites. The rest of the sites that are not included in the rating usually end up with malicious content, Blue Coat Labs ™ is actively working on the development of tracking technology, and the Web Filter database is based on the really applicable patterns of Internet users.
To process that small percentage of Unrated sites that have not yet entered the database, the filter uses a dynamic real-time rating system (DRTR ™) - a unique, patented technology that puts sites in their respective categories on the fly, while how the user makes an attempt to open such a site.

The program also has black and white list options. So adding a site to the white list - the site will load even if it is in the Unrated category, and the blocking of sites from this category is set in the filter settings. And on the other hand - you can block any site from the allowed category and it will not be loaded under any circumstances.

In addition, in the program settings you can specify the time period during which the user will be able to use the Internet. There is also an option to audit user activity, with the ability to view a list of blocked addresses.

The program has protection against ingenious ones, during the installation process you enter the administrator password without knowing which it is impossible to remove or stop the program, it is not visible in the add / remove programs, it is also not visible in the task manager.

The program is distributed free of charge - registration comes by e-mail!
