Method and system for processing data packages

A system (200) for processing a data package (100). The system comprises an input module (220) for receiving a data package (100) over a data network (230). The data package (100) comprising a header (110) and payload data (120). The system also comprises storage (240) for storing at least one criterion; a buffer (260) for temporarily storing at least a part of the data package (100); and a decision-making module (250) for determining a risk score based on the at least one criterion and the at least a part of the data package (100). The risk score being indicative of a handling action to apply to the data package (100). The system also comprises an updating module (270) for recalculating the at least one criterion in the storage (240); and a processing module (290) for determining a handling action for the data package (100), wherein the handling action is based on the risk score. The recalculation of the at least one criterion is performed asynchronously with regard to the determination of the risk score.
