Configuration for Website Filtering

Click on ‘Settings > ‘Website Filtering’

  • You can create rules that allow or prohibit access to certain websites through the website filtering section.
  • This feature is very useful in both work and home environments. You can create rules for specific users of your computer. Parents can block minors from accessing inappropriate websites, while employers can restrict employees from visiting work-related sites.
  • A log event can also be created if a user attempts to visit a site that is not in compliance with a rule.

Open the section for website filtering.

  • To open the CIS Advanced Settings interface, click ‘Settings” at the top of the CIS homepage screen.
  • Click on ‘Website Filtering’ to the left, and then choose the Rules’ tab


  • Websites can be added to a category and then to a rule.
  • Rules can be made by adding one or more “Categories”.
  • A “Category” is a group of one or more “Websites”.
  • A “Website” can be specified using a full URL, text string or text string.
  • You must define a rule as ‘Allow, ‘Block, or ‘Ask’.
  • You can toggle a rule on/off using the ‘Enable Rule” switch


  • CIS ships with seven pre-defined categories of websites that can be added to any rules you create. These are all non-modifiable lists that are managed by Comodo. The categories are: ‘Comodo Safe category’, ‘Comodo Phishing category’, ‘Comodo Malware category’, ‘Comodo PUA category’, ‘Comodo Malicious category’, Comodo Suspicious category’.
  • The two other categories, ‘Exclusions and ‘Blocked’ are by default empty and allow you to identify specific websites that should either be allowed or denied. If you need to access a website that is blocked by a particular category, you should add URLs in the ‘Exclusions” category.


  • CIS ships with two predefined rules: ‘Allowed Sites’ and ‘Blocked Sites’. Both of these can be modified.
  • The ‘Blocked Sites Rule’ will block access to any sites that fall under the ‘Comodo definable Malware sites’ or ‘Comodo definable Phishing Sites’ categories. You can add additional categories to this rule if you wish to expand its coverage.
