Payment Bridge
The Enterprise Edition 1.9′s payment bridge was certified by Coalfire, a PCI Qualified Security Assessor (QSA), to meet or exceed the PCI DSS requirements. This may actually not have been a large step technically since some believe that software residing on a secure server has only to meet industry standard coding practices, but the move is significant for the software engineers and developers that would otherwise need to demonstrate PCI compliance. Effectively, this new payment bridge lets enterprise developers “check off” PCI compliance and move on.
