Limitations and Precautions for URL Filtering

Read limitations and precautions before configuring URL filtering.

Configuring URL Category-based URL Filtering

URL categories are classified into user-defined categories and predefined categories. You can use predefined or user-defined URL categories to filter URLs.

Configuring Blacklist/Whitelist-based URL Filtering

Configuring Filtering of External Dynamic Malicious URL

The FW can filter URLs based on the external dynamic malicious URL list. By updating the external malicious URL signature database, the FW can periodically download the external dynamic URL list from the external official websites and import the list to its cache. The FW that is enabled with filtering of external dynamic malicious URL can identify and block malicious URLs.
