If you’re using Panorama to manage Prisma Access:
Toggle over to the

tab and follow the guidance there.
If you’re using Prisma Access Cloud Management, continue here.
URL filtering is also sometimes called
URL Access Management
in Prisma Access cloud mangaement.
  1. Check that your Prisma Access subscription covers Advanced URL Filtering.
  2. Explore the URL Access Management Dashboard.
    Go to
    Manage
    Configuration
    Security Services
    URL Access Management
    .
    Move between the
    Access Control
    ,
    Settings
    , and
    Best Practices
    tabs to explore the available URL filtering features.
  3. Review and customize General URL Filtering Settings.
    On the dashboard, go to
    Settings
    to see the default URL Filtering settings that apply across your Prisma Access environment, including:
    Automatically append end tokens to URLs in an EDL or a custom URL category
    If you use URLs in custom URL categories or external dynamic lists (EDLs) and do not append an ending token, it is possible to allow more URLs than you intended. For example, entering example.com as a matching URL instead of example.com/ would also match example.com.website.info or example.com.br.Prisma Access can automatically set an ending token to URLs in EDLs or custom URL categories so that, if you enter example.com, Prisma Access treats it as it would treat example.com/ and only match that URL.
    Go to
    Settings
    General Settings
    and enable the option to
    Append End Token to Entries
    .
    You can customize these settings for each deployment type (mobile users, remote networks, or service connections).
  4. Create a URL Access Management profile.
    On the URL Access Management dashboard,
    Add Profile
    and continue to specify web access settings:
    • Access Control
      displays the URL categories and lists for which you can define web access and usage policy. By default, the
      Site Access
      and
      User Credential Submission
      permissions for all categories are set to
      Allow
      .
    • For each URL category, configure
      User Credential Detection
      so that users can submit credentials only to sites in specified URL categories.
    • Enable
      Safe Search Enforcement
      to enforce strict safe search filtering.
    • Enable
      Log Container Page Only
      to log only those URLs that match the content type that is specified.
    • Enabling
      HTTP Header Logging
      provides visibility into the attributes in the HTTP request sent to a server.
    • Use the
      Advanced URL Inline Categorization
      to enable and configure real-time web page analysis and manage URL exceptions.
      • Enable local Inline Categorization
        —Enables real-time analysis of URL traffic using machine learning models, to detect and prevent malicious phishing variants and JavaScript exploits from entering your network.
      • Enable cloud Inline Categorization
        —Enables real-time analysis of URLs by forwarding suspicious web page contents to the cloud for supplemental analysis, using machine learning based detectors that complement the analysis engines used by local inline ML.
      • You can define URL
        Exceptions
        for specific web sites to exclude from inline machine learning actions.
    Note that:
    • Best practice checks are built-in to the profile to give you a live evaluation of your configuration.
    • After you’ve finished enabling a profile, you can examine profile usage to see if any security policy rules are referencing the profile.
  5. Apply the URL Access Management profile to a Security policy rule.
    A URL Access Management profile is only active when it’s included in a profile group that a Security policy rule references.
    Follow the steps to activate a URL Access Management profile (and any Security profile). Be sure to
    Push Config
