Description This article describes how to identify the web filter category of a website or domain. This step is crucial for effectively utilizing the web filter feature in FortiGate.
Scope FortiOS, FortiGate, Web Filter, FortiGuard.
Solution

Users may be uncertain about the category of a specific website or domain while configuring the web filter in FortiGate.

 

To instantly query the category of a website or domain, use the FortiGuard web filter lookup tool.

  1. Enter the website or domain and select the relevant FortiOS version.

  1. Press Enter or select the 'Search' button to display the relevant category. It is highly recommended to verify this information when configuring Web filtering on FortiGate to avoid blocking websites the business needs access to:

It can also be viewed from the FortiGate GUI as well.

 

Make sure that the FortiGate can connect to the FortiGuard server for the Lookup Rating to be successful.

Navigate to Security Profiles -> Web Rating Overrides -> Select Create New -> Enter the URL and select Lookup Rating to view the category and subcategory it belongs to.

Note
In any of the policies, make sure to apply a web filter profile in which a FortiGuard category-based filter is enabled to use this web rating service.

 

If a website may have been classified as the wrong category, fill out the 'Web Filter Classification Rating Request' form.  Submit the URL, suggested category, any screenshots, and contact information to be notified of any revision updates.

Good article, thank you.  The article also shows how to use the “Lookup rating” feature that is kind of hidden in FortiOS.  Is there an API or CLI command that can be used to do the same as the “Lookup rating” from the GUI?  The API preview function seems to suggest the API call could be “/api/v2/cmdb/webfilter/ftgd-local-rating” but this does not seem to work.  I am looking for a way to lookup a list of URLs either via Fortiguard Webportal or the FortiOS.  The task I am trying to solve is for example checking how a list of 100 URLs are categorized.

Is that possible somehow?

Found my problem - the API call must be placed against a Fortigate that has a valid “WebFilter” license.  It won’t work vs a Fortigate that does not have that license.
