Antivirus profiles can submit potential zero-day viruses to FortiSandbox for inspection. Based on FortiSandbox's analysis, the FortiGate can supplement its own antivirus database with FortiSandbox's threat intelligence to detect files determined as malicious or suspicious. This augments the FortiGate antivirus with zero-day detection.
FortiSandbox can be used with antivirus in both proxy-based and flow-based inspection modes. The FortiGate first examines the file for any known viruses. When a match is found, the file is tagged as known malware. If no match is found, the files are forwarded to FortiSandbox using the following options:
All Supported Files: all files matching the file types defined in the scan profile of the FortiSandbox are forwarded.
Suspicious Files Only: files classified by the antivirus as having any possibility of active content are forwarded to FortiSandbox. When using FortiGate Cloud Sandbox, we recommend selecting this option due to its submission limits.
None: files are not forwarded to FortiSandbox.
For more information, see Sandboxing.
