Advanced Malware Protection protects against zero-day and targeted file-based threats by:
•
Obtaining each file’s reputation.
•
Analyzing behavior of certain files that are not yet known to the reputation service.
•
Notifying you about files that are determined to be threats after they have entered your network.

alerted, and the file and its new verdict appear in the AMP Verdict Updates report. You can investigate
the point-of-entry transaction as a starting point to remediating any impacts of the threat.
