Request for FortiSandbox Academic/Evaluation Image for Student Research

Hello Fortinet community,

I am a Systems and Network Administration student working on my final-year thesis on
"Implementing sandboxing technology for proactive security of incoming network flows."

I need access to a FortiSandbox image for lab testing and practical research. I do not have a commercial serial number with support.

Could anyone advise if there is an academic or evaluation image available, or guide me on how to obtain one for student research purposes?

Thank you very much for any assistance.
