Determiners of the Risk Factor of a Suspected Violation 
When the appliance scans a message for DLP violations, it assigns a risk factor score to the message. 
This score indicates the likelihood that the message contains a DLP violation. A score of 0 means the 
message almost certainly does not contain a violation. A score of 100 means it almost certainly does 
contain a violation.
