Enable Free WildFire Forwarding

WildFire is a cloud-based virtual environment that analyzes and executes unknown samples (files and email links) and determines the samples to be malicious, phishing, grayware, or benign. With WildFire enabled, a Palo Alto Networks firewall can forward unknown samples to WildFire for analysis. For newly-discovered malware, WildFire generates a signature to detect the malware and distributes it to all firewalls with active WildFire subscription within minutes. This enables all Palo Alto next-generation firewalls worldwide to detect and prevent malware found by a single firewall. Malware signatures often match multiple variants of the same malware family, and as such, block new malware variants that the firewall has never seen before. The Palo Alto Networks threat research team uses the threat intelligence gathered from malware variants to block malicious IP addresses, domains, and URLs.
A basic WildFire service is included as part of the Palo Alto Networks next-generation firewall and does not require a WildFire subscription. With the basic WildFire service, you can enable the firewall to forward portable executable (PE) files. Additionally, if you do not have a WildFire subscription, but you do have a Threat Prevention subscription, you can receive signatures for malware WildFire identifies every 24- 48 hours (as part of the Antivirus updates).
Beyond the basic WildFire service, a WildFire subscription is required for the firewall to:
  • Get the latest WildFire signatures within a minute of availability—new signatures are released every five minutes.
  • Forward advanced file types and email links for analysis.
  • Use the WildFire API.
  • Use a WildFire appliance to host a WildFire private cloud or a WildFire hybrid cloud.
If you have a WildFire subscription, go ahead and get started with WildFire to get the most out of your subscription. Otherwise, take the following steps to enable basic WildFire forwarding:
  1. Confirm that your firewall is registered and that you have a valid support account as well as any subscriptions you require.
    1. Log in to the Palo Alto Networks Customer Support Portal(CSP) and on the left-hand side navigation pane, select
    2. Verify that the firewall is listed. If it is not listed, select
      Register New Device
      and continue to Register the Firewall.
    3. (
      ) If you have a Threat Prevention subscription, be sure to Activate Subscription Licenses.
  2. Log in to the firewall and configure WildFire forwarding settings.
    1. Select
      and edit the General Settings.
    2. Set the
      WildFire Public Cloud
      field to forward files to the WildFire global cloud at:
      You can also forward files to a regional cloud or a private cloud based on your location and your organizational requirements.
    3. Review the
      File Size Limits
      for PEs the firewall forwards for WildFire analysis. set the
      Size Limit
      for PEs that the firewall can forward to the maximum available limit of 10 MB.
      As a WildFire best practice, set the
      Size Limit
      for PEs to the maximum available limit of 10 MB.
    4. Click
      to save your changes.
  3. Enable the firewall to forward PEs for analysis.
    1. Select
      Security Profiles
      WildFire Analysis
      a new profile rule.
    2. Name
      the new profile rule.
    3. Add
      a forwarding rule and enter a
      for it.
    4. In the
      File Types
      column, add
      files to the forwarding rule.
    5. In the
      column, select
      to forward PEs to the WildFire public cloud.
    6. Click
  4. Apply the new WildFire Analysis profile to traffic that the firewall allows.
    1. Select
      and either select an existing policy rule or create a new policy rule as described in Set Up a Basic Security Policy.
    2. Select
      and in the Profile Settings section, set the
      Profile Type
    3. Select the
      WildFire Analysis
      profile you just created to apply that profile rule to all traffic this policy rule allows.
    4. Click
  5. Enable the firewall to forward decrypted SSL traffic for WildFire analysis.
  6. Review and implement WildFire best practices to ensure that you are getting the most of WildFire detection and prevention capabilities.
  7. Commit
    your configuration updates.
  8. Verify that the firewall is forwarding PE files to the WildFire public cloud.
    WildFire Submissions
    to view log entries for PEs the firewall successfully submitted for WildFire analysis. The Verdict column displays whether WildFire found the PE to be malicious, grayware, or benign. (WildFire only assigns the phishing verdict to email links). The Action column indicates whether the firewall allowed or blocked the sample. The Severity column indicates how much of a threat a sample poses to an organization using the following values: critical, high, medium, low, information.
  9. (
    Threat Prevention subscription only
    ) If you have a Threat Prevention subscription, but do not have a WildFire subscription, you can still receive WildFire signature updates every 24- 48 hours.
    1. Select
      Dynamic Updates
    2. Check that the firewall is scheduled to download, and install Antivirus updates.
