Scan Profile Pre-Filter Tab
Use the Pre-Filter page file type panel to define file types and URLs that are allowed to enter the job queue if they are from a sniffer, adapter, or device other than FortiMail.

Files or URLs submitted through On-Demand, RPC JSON API, network share, or FortiMail are always put into the job queue even if their file types are not set to enter the job queue. |
To allow a file type to enter the job queue:
Click the toggle button to enable it. If the button is grayed out, files of that type are dropped.
To enable pre-filter for selected file types:
Click the toggle button to enable it. If the button is enabled, only suspicious files or unrated URLs are forwarded for VM Scan. The files and URLs will still go through the Static Scan stage.

To use trust results from trusted resources during pre-filter:
Click the toggle button to enable it. If the button is enabled, files rated by that resources are pre-filtered.

When Trusted Vendor is enabled, executable files from a small internal list of trusted vendors skip the sandboxing scan step.
When Trust Domain is enabled, files downloaded from a small internal list of trusted domains skip the sandboxing scan step.
