WildFire by Palo Alto Networks is a cloud-based malware prevention engine that uses machine learning and crowdsourced intelligence to protect organizations from file-based threats. The system combines static and dynamic analysis with a custom-built hypervisor to identify and prevent sophisticated and evasive threats, including zero-day malware. It operates through cloud-delivered infrastructure and includes inline machine learning capabilities for preventing malicious content in common file types without requiring cloud analysis. The service can be deployed as a public cloud service, in hybrid environments, or air-gapped environments through private cloud appliances, and is integrated into Prisma Cloud's Data Security Posture Management (DSPM) module for scanning files stored in cloud object storage environments.
