A system for validating incoming data, the system comprising: a mirror computer system (104; 300), comprising: a mirror memory element; a mirror display device, configured to simulate a primary display device; a mirror communication device, configured to receive a first instance of incoming data at a particular time; a mirror processor, communicatively coupled to the mirror memory element, the mirror display device, and the mirror communication device; and a primary computer system (102; 200), comprising: a primary memory element; a primary communication device, configured to receive a second instance of the incoming data at the particular time; a primary processor, communicatively coupled to the primary memory element and the primary communication device, the primary processor configured to process the second instance of the incoming data, when the output comprises acceptable results, wherein the mirror processor is configured to: receive a duplicate of software associated with the primary computer system (102; 200), via the mirror communication device; store the duplicate, via the mirror memory element; process the first instance of the incoming data, when received via the mirror communication device, by executing the duplicate using the first instance of the incoming data, wherein execution of the duplicate results in a simulation of operation of the primary computer system; and present output via the mirror display device, based on processing the first instance of the incoming data, wherein the output comprises one of acceptable results and unacceptable results. a mirror computer system (104;
