A system (10) for analyzing data traffic is described. The system (10) comprises a data processing module (12), wherein the data processing module (12) comprises a plurality of data processing units (22). The plurality of data processing units (22) comprise a first data processing unit and a second data processing unit. The data processing units (22) each comprise a data input (24) for receiving a data stream ( s i ) and a result output (26) for outputting a result. The first data processing unit is configured to analyze data packets and/or bulks of data packets by means of a first deep packet inspection technique. The second data processing unit is configured to analyze data packets and/or bulks of data packets by means of a second deep packet inspection technique. The first deep packet inspection technique is different from the second deep packet inspection technique. A data stream ( s i ) being associated with the first processing unit and/or the second processing unit is a bulk of data packets. Further, a data traffic analysis method for analyzing data traffic is described.
