How are websites filtered using FortiGuard category filters?

FortiGuard category filters are designed to enhance cybersecurity by categorizing websites based on their content and applying specific access policies accordingly. When websites are filtered using these category filters, the filtering process occurs based on the content type of the website. This means that if a website falls into a category that is deemed inappropriate or restricted—such as adult content, gambling, or phishing—it can be blocked entirely, regardless of who is trying to access it.

The underlying principle is to ensure that users are protected from malicious or harmful content and that organizational policies regarding internet usage are enforced. Therefore, the filtering is content-based, making it an effective tool in the management of safe browsing practices. The other options don't capture this specific mechanism of content-based filtering that FortiGuard implements.
