What is Sandbox Inspection?

Sandbox inspection is a network process that allows files to be sent to a separate device, such as FortiSandbox, to be inspected without risking network security. This allows the detection of threats which may bypass other security measures, including zero-day threats.

When a FortiGate uses sandbox inspection, files are sent to the FortiSandbox. Then the FortiSandbox uses virtual machines (VMs) running different operating systems to test the file, to determine if it is malicious. If the file exhibits risky behavior, or is found to contain a virus, a new signature can be added to the FortiGuard AntiVirus signature database.
