No. You are not required to use an ASV for items from the PCI DSS outside of item 11.2.2. With that said, it is a very good idea to work with an Approved Scanning Vendor for internal scanning and penetration testing. Pen-testing for PCI compliance has a few unique elements that general security consultants may not be familiar with. It would certainly be an unfortunate surprise to submit what you thought was evidence of compliance for the PCI penetration testing requirement to an auditor or your bank and have them tell you it’s not sufficient. This would obviously be a huge waste of time, money and other valuable resources.
