A firewall in a WildFire hybrid cloud deployment can
forward certain samples to one of the Palo Alto Networks-hosted
WildFire public clouds and other samples to a WildFire private cloud
hosted by a WildFire appliance. A WildFire hybrid cloud deployment
allows the flexibility to analyze private documents locally and
inside your network, while the WildFire public cloud analyzes files
from the Internet. For example, forward Payment Card Industry (PCI)
and Protected Health Information (PHI) data exclusively to the WildFire
private cloud for analysis, while forwarding Portable Executables
(PEs) to the WildFire public cloud for analysis. In a WildFire hybrid
cloud deployment, offloading files to the public cloud for analysis
allows you benefit from a prompt verdict for files that have been
previously processed in the WildFire public cloud, and also frees
up the WildFire appliance capacity to process sensitive content.
Additionally, you can forward certain file types to the WildFire
public cloud that are not currently supported for WildFire appliance
analysis, such as Android Application Package (APK) files.
In a WildFire hybrid cloud deployment, there might be some cases
where a single file matches your criteria for both public cloud
analysis and private cloud analysis; in these cases, the file is
submitted only to the private cloud for analysis as a cautionary
measure.
