By default, the firewall decodes files that have been encoded
or compressed up to four times, including files that have been compressed
using the ZIP format. The firewall then inspects and enforces policy
on the decoded file; if the file is unknown, the firewall forwards
the decoded file for WildFire analysis. While the firewall cannot
forward complete ZIP archive files for Advanced WildFire analysis,
you can submit files directly to the Advanced WildFire public cloud
using the WildFire portal or the WildFire API.
