The present invention extends to methods, systems, and computer program products for securely inspecting electronic messages. A computer system receives a control message that is passed through one or more receiving path components, positioned in a message receiving path, to a security component. The security component authenticates the received control message and passes the received control message to an inspection control component. The inspection control component activates message inspection in accordance with instructions contained in the received control message. When message inspection is activated, the computer system passes accessed messages to corresponding inspection components positioned in message paths (either receiving or sending) of the accessed message. The inspection component generates an inspection report (e.g., including a portion of contents of the accessed message) in accordance with instructions contained in a previously authenticated control message.
