Log – Create an event log when the sandboxing DB detects there is a malware content.

Inspect selected downloaded files – If enabling this option, the Nebula device would hold the downloaded file (which has never been inspected before) for 2 seconds to inquiry cloud Sandboxing DB and wait for its response to identify whether it is a malicious file or not. But if the process takes longer than 2 seconds, the inspected file may still be forwarded to the customer.
