This article discusses how to customize the Warning / Block page with messaging and branding that is consistent with the company's security policy.
When users try to go to a resource that matches a security rule with the Block or Prompt action, they are instead redirected to a webpage that explains why they can't directly access the resource. The default Warning / Block webpage uses the Cato logo, branding, and wording. This can be customized to meet the requirements of your company.
Customers can provide feedback that an Internet page for a website is in the wrong category. For example, they can report that a news website is incorrectly classified as Social.
When the user clicks the link to report that a website or application has the wrong category, the Cato Management Application generates a reference ID that is shown to the user. In addition, an event is generated for the admins in your account and the Cato Security team. Admins can use the Events screen to review and analyze these events with the reference IDs.
The Cato Security team regularly reviews reported wrong categories and validates that the content for the category is correct. When websites or applications belong to the wrong category, the Cato Security team updates the definition of the category. We recommend that you override the default category for the domain or website.
After a few minutes, the wrong category link is no longer active. Users are able to click the link again after they refresh the webpage.
When a redirect page is displayed, an event is generated. To easily find this event, you can choose to display the Event ID on the redirect page. This enables users to provide the Event ID, which you can add to the Event Reference ID filter on the Events page. For more information, see Analyzing Events in Your Network.
The Warning page is displayed to a user if they go to a resource that matches a security rule with the Prompt action. The Block page is displayed to a user if they go to a resource that matches a security rule with the Block action. You can customize the look and feel, wording, and some fields of the Warning and Block pages independently.
The selected language applies to both redirect pages. These fields cannot be customized:
-
URL - Shows the URL of the website the user is trying to connect to
-
Warning/Block Reason - Shows the reason why this website is problematic or blocked
-
Category - The category of the website the user is trying to connect to
The Warning / Block Page customization screen lets you add your corporate logo to the redirect pages for the end-users. These are the guidelines for the logo file:
-
The maximum file size is 600 KB
-
Supported file types are JPG, PNG, GIF, and SVG
You can configure the Warning / Block Page to be displayed in different languages. When you configure support for a language, the default text on the page is shown in the target language, and you can use the same customization options that exist for English. For example, you can use a text editor to edit the message in the target language.
When you define multiple languages for the page, the browser shows the page according to its language preferences. You can choose to set a Default Language to display when the preferred browser languages aren't supported, or if the browser has no preferred language configured. For example, an admin defines Chinese, Japanese, and Italian language support, and sets Japanese as the Default Language:
-
A user whose preferred browser language is Italian sees an Italian message
-
A user whose preferred browser languages are Korean and Vietnamese sees the default Japanese message
To configure language localization:
-
From the navigation menu, click Account > Warning / Block Page.
-
In the Language drop-down menu, click Add Language. The Localization Support panel opens.
-
In the Localization Support panel, select the required languages.
-
Select the Default Language.

Click Apply.

Hello Jørn-Morten!
My apologies that this comment was not responded to earlier! I see that you have provided other comments recently that provide great feedback for us. As I mentioned in one of those comments, we are busy setting up the Cato Online Community which includes a topic called "Cato Product Suggestions". I could open a post for you, but I think it might be better if you did this. The link to the community topic is here.
You can also email the community on people-pop@catonetworks.com.
Kind Regards,
