Working with Categories

This article discusses how to use the predefined Cato categories and create custom categories to meet the specific needs of your organization.

Working with Categories

The Categories screen shows you Cato Cloud system and custom categories. Categories are global objects that you can use to customize the Networking, WAN and Internet firewall rules to meet the specific needs of your network.

The system categories are predefined and group web content into common categories, such as News, Gambling, Weapons, and so on. You can also create custom categories to include a group of system categories, specific websites, services, and applications.

When you add multiple categories to a single networking, WAN, or Internet firewall rule, there is an OR relationship between them.


Showing a Category

The Categories screen lets you show the details for each system and custom category.

To show a category:

  1. From the navigation panel, click Assets > Categories.

    The Categories panel opens, displaying the Custom Categories tab and the System Categories tab.

  2. Select if you want to show the predefined System Categories or Custom Categories.

  3. Click the Name or Description column headings to sort the table in alphabetical order.

Creating a Custom Category

Custom categories give you increased control over the corporate network and security policy. You can define the applications, Internet content, and services that belong to the new category. It is a global object that you can use for the Firewall and Networking rules, events, analysis and so on. These are the types of content that you can use to define a custom category:

  • Applications and custom applications

  • Services and custom services

  • Fully Qualified Domain Names (FQDN) and Top Level Domains (TLD)

    • FQDN is an exact match of the fully qualified domain (for example, the FQDN only matches

    • TLD matches all subdomains that end in the TLD (for example, the TLD matches

When there are multiple content types in a custom category, such as a Domain Name and a Service, there is an OR relationship between them.

To create a custom category:

  1. From the navigation panel, click Assets > Categories.

  2. Click the Custom Categories tab.

  3. Click New. The Add Category panel opens.

  4. Enter the Name and Description for the category.

  5. From the Members drop-down menu, select the content type that you are adding to this category.

  6. Repeat the previous step to add more content types.

  7. Click Apply. The custom category is added.

  8. Click Save. The custom category is created.

Deleting Custom Categories

You can delete one or more custom categories when they are no longer needed. You cannot delete system categories.

To delete custom categories:

  1. From the navigation panel, click Assets > Categories.

  2. Click the Custom Categories tab.

  3. Click Delete.png (Delete) next to the custom category to delete.

    The custom category is removed.

  4. Click OK. The custom category is deleted.

    The layout has probably changed since this article was last updated, but TLDs are not an option in the members dropdown of custom categories (FQDNs are still there though).

    Would it be accurate to assume that the "Domain" member selection acts as the previous TLD option and includes all subdomains of any given domain name?
