  • receiving a communication from a messaging entity;

    deriving a risk profile for the communication comprising;

    queuing the communication for interrogation by a plurality of interrogation engines, each interrogation engine of a particular type designed to test the communication for a particular security risk;

    performing a load evaluation on an interrogation engine of one of the particular types based upon the plurality of interrogation engines queued to interrogate the communication;

    determining that the load evaluation exceeds a threshold, and in response adjusting the plurality of the interrogation engines by generating a new instance of an interrogation engine of the one of the particular types based upon the plurality of interrogation engines queued to interrogate the communication;

    aggregating output of the plurality of interrogation engines with data associated with previously received communications to form the risk profile for the communication;

    determining, using one or more data processors, a reputation score associated with the communication based upon the risk profile;

    wherein the reputation score is indicative of reputation of the messaging entity;

    wherein the determined reputation score is used in deciding what action is to be taken with respect to communications associated with the messaging entity.
