According to one embodiment, a multi-level secure information retrieval system includes an enterprise access service tool coupled to one or more client applications and at least one gateway managed by an enterprise. The enterprise access service tool executes services operating in a service oriented architecture. The enterprise access service tool receives requests from the client applications, associates each of the requests with one of a plurality of differing security levels, and transmits the requests to the gateway. The gateway transmits the requested information back to the client applications in which the information is filtered by the gateway according to their associated security levels.
