1. A computer-implemented method for identifying data leakage across an Internet connection, comprising the steps of: a. accessing via threat analysis software hosted on at least one marketing services provider (MSP) server an Internet website hosted at a publisher server, wherein the MSP server is configured to mimic a standard web browser such that it appears from the Internet website as if the MSP server is a consumer using the standard web browser to access the Internet website but wherein the MSP server is actually configured to analyze the Internet website for data leakage; b. searching the Internet website to identify any third-party tags on the Internet website; c. determining whether any of the third-party tags forward requests to subsequent third-party tags, thereby allowing the subsequent third-party tags to piggyback through inspection of the Internet website at the time the Internet website is loaded; d. if it is determined that subsequent third-party tags are piggybacking on the Internet website, dynamically calculating an individual threat score associated with each third-party tag found on the Internet website based on use by each third-party tag of any personal information associated with an individual accessing the Internet website; e. if individual threat scores are calculated, calculating a cumulative threat score associated with the Internet website based on the individual threat scores; and f. if a cumulative threat score is calculated, then determining whether the cumulative threat score is above a threshold threat score, and if so identifying the Internet website as a data leakage threat.
