A computer-implemented method for identifying data leakage, comprising the steps of: a. accessing via software hosted at at least one marketing services provider, MSP, server a website hosted at a publisher server wherein the MSP server is configured to mimic a standard web browser such that it appears from the website as if the MSP server is using a standard web browser; b. searching the website to identify third-party tags or pixels on the website; c. if third-party tags or pixels are found, dynamically calculating an individual threat score associated with each third-party tag or pixel found on the website based on use by each third-party tag or pixel of any personal information associated with an individual accessing the website; d. if third-party tags or pixels are found, determining whether any of the third-party tags or pixels are chained to any forwarded third-party tags or pixels; e. if forwarded third-party tags or pixels are found based on determining whether any of the third-party tags or pixels are chained to any forwarded third-party tags or pixels, dynamically calculating an individual threat score associated with each forwarded third-party tag or pixel found on the website based on use by each forwarded third-party tag or pixel of any personal information associated with the individual accessing the website; f. if forwarded third-party tags or pixels are found and individual threat scores associated with each forwarded third-party tag or pixel are calculated, assigning the individual threat score associated with each forwarded third-party tag or pixel to any third-party tag or pixel linked to the forwarded third-party tag or pixel if the individual threat score associated with the forwarded third-party tag or pixel is higher than the individual threat score associated with the third-party tag or pixel; g. calculating a cumulative threat score associated with the website based on the individual threat scores of third-party tags or pixels found and forwarded third-party tags or pixels found; and h. 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 website as a data leakage threat. a. accessing via software hosted at at least one marketing services provider, MSP, server a website hosted at a publisher server wherein the MSP server is configured to mimic a standard web browser such that it appears from the website as if the MSP server is using a standard web browser; b. searching the website to identify third-party tags or pixels on the website; c. if third-party tags or pixels are found, dynamically calculating an individual threat score associated with each third-party tag or pixel found on the website based on use by each third-party tag or pixel of any personal information associated with an individual accessing the website; d. if third-party tags or pixels are found, determining whether any of the third-party tags or pixels are chained to any forwarded third-party tags or pixels; e. if forwarded third-party tags or pixels are found based on determining whether any of the third-party tags or pixels are chained to any forwarded third-party tags or pixels, dynamically calculating an individual threat score associated with each forwarded third-party tag or pixel found on the website based on use by each forwarded third-party tag or pixel of any personal information associated with the individual accessing the website; f. if forwarded third-party tags or pixels are found and individual threat scores associated with each forwarded third-party tag or pixel are calculated, assigning the individual threat score associated with each forwarded third-party tag or pixel to any third-party tag or pixel linked to the forwarded third-party tag or pixel if the individual threat score associated with the forwarded third-party tag or pixel is higher than the individual threat score associated with the third-party tag or pixel; g. calculating a cumulative threat score associated with the website based on the individual threat scores of third-party tags or pixels found and forwarded third-party tags or pixels found; and h. 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 website as a data leakage threat.
