Systems, methods, and apparatus are provided for system mapping based on processing of custom network packets. A token processor may deploy a network agent to a system of record (SOR). The network agent may scan the SOR and extract SOR metadata through a set of API calls. The network agent may aggregate the SOR data and generate a token according to parameters established by the token processor. The token processor may process the token through a neural network to generate a set of output vectors for the SOR. A system mapping engine may determine relationships between network SORs based on the output vectors and generate an integrated visual representation of enterprise systems. The output vectors may be adjusted based on new tokens received from the SOR and the visual representation may be updated in real time.
