Cato's system categories help you to easily manage the domains for different types of Internet content, such as Gambling or Hacking. However sometimes you don’t know which category a domain belongs to, and how policies might impact traffic to the domain. You can use Domain Lookup to show the Cato system categories for a specific domain.

For example, an Internet Firewall policy blocks the Gambling category. There are users that need to access a website related to gambling, you can't if that website is included in the Gambling category.
