Modifying the artificial intelligence sensitivity level

By default, Messaging Gateway blocks malicious content using static and dynamic artificial intelligence as well as virus definitions. The sensitivity level determines the way in which the system uses artificial intelligence to detect malware and to scan for threats for which no known definitions exist. In addition to scanning for known threats (static), Messaging Gateway uses artificial intelligence technology to scan for unusual behaviors (dynamic) to target potentially infected message bodies and attachments.
Artificial intelligence scanning involve a trade-off between malware-detection rates and false positives. Lower artificial intelligence sensitivity levels may miss more malware but produce fewer false positives. Higher artificial intelligence sensitivity levels may catch more malware but cause more false-positive detections. For environments where high false positives are acceptable, choose
High Detection Sensitivity
to increase blocking of malicious content. To minimize false positives, choose
Low Detection Sensitivity
to provide the best blocking of malicious content at the lowest false-positive cost.
