PubMatic, which provides online publishers with technology and services to better manage their advertising inventory, today launched its Data Firewall product for publishers. Data Firewall gives publishers visibility into 3rd party companies that are tracking the publisher's audience via pixels or cookies and causing data leakage.
Data leakage occurs when 3rd parties track a publisher's audience without the knowledge of the publisher. PubMatic estimates that data leakage is costing publishers up to $ 1 billion annually in lost revenue. PubMatic's Data Firewall is gives publishers transparency into this data leakage and at the same time allows them to see which 3rd parties are producing the highest ad revenue for the publishers. This will allow publishers to evaluate the value of those 3rd party relationships.
PubMatic is privately held, backed by funding from Draper Fisher Jurvetson, Nexus Venture Partners, and Helion Ventures, and has seven offices around the world in the US, Europe, and Asia.
