I'm actually working on a project wich is developping a vulnerabilty scanner in order to perform external vulnerability assessment approved by the PCI SSC. In other terms, I want to developp a scan solution that will make me an ASV by PCI SSC. Can you please provide some technical informations that will help me to successfully complete the project. Moreover, I heard that it is possible to become an ASV by using other's solution, what do you think about this? Thanks for helping!
