FortiSandbox File On-Demand

Hi Forum,

I have recently tried to upload a number of large zip files (500MB - 2GB) onto FortiSandbox for analysis.

I have checked the settings, even 2GB should still be allowed.

However, I am stuck on 100% on the uploading process until timeout (increased to 60mins) kicks in.

I have also tried to change the prescan-config time but it does not allow somehow,

https://docs.fortinet.com/document/fortisandbox/latest/cli-reference/707722/prescan-config

I then split the files into multiple smaller files with 7zip.

But somehow only zip.001 has promising file count (e.g., 1001) and the rest (zip.002, zip.003, etc) only have 1 file count.

Here are my questions,

1. How to change the prescan-config if it is why my uploading process got stuck?
2. How does the scanning mechanism work? Would the analysis still be accurate for multiple split zipped files?
3. If multiple file anaylsis is feasible, how do I consolidate the multiple reports into one?

Thank you!
