does qualys scanner serches for PCI data ? i.e. PAN numbers or magnetic strip data ?
The answer is YES if you are looking for an Web application leaking a credit card number on the response to a user request. Use Qualys WAS.
If you want to look in a specific file on a system for credit card numbers, use Qualys PC "File content check"
If you are looking to see if a PC or storage device has card data stored in the disk, then the answer is "NO", you will need a data classification solution that can dig into file content.
