Providing security-related services for enterprise service requests includes receiving a service request from an endpoint, determining the transaction parameter from the received service request, determining a subroutine for execution based on the transaction parameter, communicating with a data server to execute the subroutine, receiving subroutine results from the data server based on the executed subroutine, applying context-specific rules to the request based on instructive data specified in the subroutine results, determining a response based on the subroutine results and the applied context-specific rules, and communicating the response to the endpoint. Some embodiments may also include accessing transaction rules associated with the transaction parameter, determining an additional subroutine for execution based on the transaction rules, communicating with a data server to execute the additional subroutine, receiving additional subroutine results from the data server based on the executed additional subroutine, and communicating the results to the endpoint.
