K9 Web Protection is a content filtering solution for your home computer. Its job is to provide you with a family-safe Internet experience, where YOU control the Internet content that enters your home.
K9 Web Protection implements the same enterprise-class Web filtering technology used by Blue Coats Fortune 500 customers around the world, wrapped in simple, friendly, and reliable preference pane for your Mac.
Blue Coats unique Web filtering technology divides Internet content into 60 distinct categories. These categories are stored in the master Blue Coat database, through which we maintain and update more than 15 million ratings of websites and domains.
A Web site will fall into one or more of these categories, based on the content of the site. To meet your particular preferences and needs, you can configure the software to allow or block specific categories.
Known Issues:
1. When browsing a web site that is blocked by K9 Web Protection, selecting the option to Allow This Site or Allow This Category intermittently does not accept the K9 administrator password.
2. K9 error and warning pages that include the option to override the Web filter intermittently do not accept the K9 administrator password. Refreshing the page should clear the problem and allow Internet access again.
NOTE: K9 Web Protection is free for home use.

Main features:
- Block 60 Content Categories: Blue Coats unique Web filtering technology divides Internet content into 60 content categories.

To meet your particular needs and preferences, you can configure the software to block or allow specific categories.
- Time Restrictions: K9 Web Protection enables you to restrict the time of day users can access Web sites. If there are specific times when you do and do not want your family accessing the Web, this feature assists you in enforcing that policy.
- Web Site Exceptions: In addition to the defined and custom protection levels, K9 Web Protection allows you to explicitly block or allow access to specific Web sites. For example, K9 is blocking a site, but you want to allow access to it, but not any others in the category.

This feature is useful to alert a parent, teacher, or other care provider that someone under his or her supervision might be stumbling onto offensive or inappropriate content. K9 also enables Time Out Settings. If a user attempts to visit too many blocked sites in a specified period of time, K9 completely blocks access to the Web for a specified time.

- Web Search Options: K9 Web Protection offers the option of enforcing the use of Google SafeSearch, which diminishes the amount of adult material that might be returned as a result of an Internet search.
