    Where Can I Use This?What Do I Need?
    • Prisma Access (Managed by Strata Cloud Manager)
    • Prisma Access (Managed by Panorama)
    • NGFW (Managed by Strata Cloud Manager)
    • NGFW (Managed by PAN-OS or Panorama)
    • VM-Series
    • CN-Series
    • Advanced Threat Prevention (for enhanced feature support)
    Inline Cloud Analysis is an Advanced Threat Prevention feature that enables the detection of advanced, highly-evasive zero-day command-and-control (C2) threats and command injection and SQL injection vulnerabilities in real-time by querying the Advanced Threat Prevention cloud service. Inline Cloud Analysis protection is delivered through your Anti-Spyware and Vulnerability Protection security profiles, with advanced C2 (command-and-control) and spyware threats handled by the former, and command injection and SQL injection vulnerabilities by the latter.
    Supported firewalls operating PAN-OS 11.2 and later deployments can also access Local Deep Learning for Advanced Threat Prevention. Local Deep Learning complements the cloud-based Inline Cloud Analysis component of Advanced Threat Prevention by providing a mechanism to perform fast, local deep learning-based analysis of zero-day and other evasive threats. Updates to Local Deep Learning models are delivered through content updates. Due to the additional system resources necessary to run local Deep Learning detection modules, Local Deep Learning is only available on the following platforms:
    • PA-5400 Series, excluding the PA-5450 appliance.
    • VM-Series (must allocate at least 16GB of total memory)
    • VM-Series Public Cloud
    • VM-Series Private Cloud
    To enable and configure Inline Cloud Analysis, and Local Deep Learning, you must activate your Advanced Threat Prevention license and create (or modify) the Anti-Spyware and Vulnerability Protection security profile. Then configure the policy settings for each category analysis engine and then attach the profiles to a security policy rule.
    For more information on creating security policy rules, refer to the Policy chapter of the PAN-OS® Administrator’s Guide.

        3. Click OK.
      2. (For the following releases only: PAN-OS 10.2.11 and later and PAN-OS 11.1.5 and later) Configure the proxy server through the firewall CLI.
        1. Access the firewall CLI.
        2. Configure the base proxy server settings using the following CLI commands:
          set deviceconfig system secure-proxy-server <FQDN_or_IP>
set deviceconfig system secure-proxy-port <1-65535>
set deviceconfig system secure-proxy-user <value>
set deviceconfig system secure-proxy-password <value>
          The proxy server password must contain a minimum of seven characters.
        3. Enable the proxy server to send requests to the inline cloud service servers using the following CLI command:
          debug dataplane mica set inline-cloud-proxy enable
        4. View the current operational status of proxy support for inline cloud services using the following CLI command:
          debug dataplane mica show inline-cloud-proxy
          For example:
          debug dataplane mica show inline-cloud-proxy

Proxy for Advanced Services is Disabled
    10. (Optional) Set the Cloud Content Fully Qualified Domain Name (FQDN) used by the firewall to handle inline cloud analysis service requests. The default FQDN connects to hawkeye.services-edge.paloaltonetworks.com and then resolves to the closest cloud services server. You can override the automatic server selection by specifying a regional cloud content server that best meets your data residency and performance requirements.
      The Cloud Content FQDN is a globally used resource and affects how other services that rely on this connection sends traffic payloads.
      Verify that the firewall uses the correct Content Cloud FQDN (DeviceSetupContent-IDContent Cloud Setting) for your region and change the FQDN if necessary:
      If your NGFW is configured inline to facilitate a SaaS Security deployment, please note that the FQDNs located in France and Japan do not currently support SaaS Security functionality.
