Custom URL Categories—Select Objects > Custom Objects > URL Category to define a custom URL category. You can base custom URL categories on a list of URLs or on multiple predefined categories.

External Dynamic URL Lists— Select Objects > External Dynamic Lists to enable the firewall to import a list of URLs from a web server.

Pre-defined Categories—Lists all URL categories defined by PAN-DB, the Palo Alto Networks URL, and the IP cloud database.

alert—Allows access to the web site but adds an alert to the URL log each time a user accesses the URL.

allow—Allows access to the web site.

block—Blocks access to the website. If the Site Access to a URL category is set to block, then the User Credential Submission permissions are automatically also set to block.

continue—Displays a warning page to users to discourage them from accessing the website. The user must then choose to Continue to the website if they decide to ignore the warning.

override—Displays a response page that prompts the user to enter a valid password to gain access to the site. Configure URL Admin Override settings (DeviceSetupContent ID) to manage password and other override settings. (See also the Management Settings table in Device > Setup > Content-ID).

none (custom URL category only)—If you created custom URL categories, set the action to none to allow the firewall to inherit the URL filtering category assignment from your URL database vendor. Setting the action to none gives you the flexibility to ignore custom categories in a URL filtering profile while allowing you to use the custom URL category as a match criteria in policy rules (Security, Decryption, and QoS) to make exceptions or to enforce different actions. To delete a custom URL category, you must set the action to none in any profile where the custom category is used. For information on custom URL categories, see Objects > Custom Objects > URL Category.

alert—Allows users to submit credentials to the website, but generate a URL Filtering log each time a user submits credentials to sites in this category.

allow (default)—Allows users to submit credentials to the website.

block—Blocks users from submitting credentials to the website. A default anti-phishing response page blocks user credential submissions.

continue—Displays a response page to users that prompts them to select Continue to submit credentials to the site. By default, an anti-phishing continue page displays to warn users when they attempt to submit credentials to sites to which credential submissions are discouraged. You can choose to create a custom response page to warn users against phishing attempts or to educate them against reusing valid corporate credentials on other websites.
