Enable Basic 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:
- Confirm that your firewall is registered and that you have a valid support account as well as any subscriptions you require.
- Log in to the Palo Alto Networks Customer Support Portal(CSP) and on the left-hand side navigation pane, select.AssetsDevices
- Verify that the firewall is listed. If it is not listed, selectRegister New Deviceand continue to Register the Firewall.
- (Optional) If you have a Threat Prevention subscription, be sure to Activate Licenses and Subscriptions.
- Log in to the firewall and configure WildFire forwarding settings.
- Selectand edit the General Settings.DeviceSetupWildFire

- Enable the firewall to forward decrypted SSL traffic for WildFire analysis.
- Review and implement WildFire best practices to ensure that you are getting the most of WildFire detection and prevention capabilities.

- Verify that the firewall is forwarding PE files to the WildFire public cloud.Selectto 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.MonitorLogsWildFire Submissions
- (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.
- Select.DeviceDynamic Updates
- Check that the firewall is scheduled to download, and install Antivirus updates.
