How much does it cost to become PCI DSS compliant?
The cost will depend on the size of your business and which Qualified Security Assessor (QSA) or Approved Scanning Vendor (ASV) you choose to carry out your assessments. Any cost should be compared to the effect on your business if card data you held was stolen. As well as possible fines levied by the card schemes and other costs associated with actual card data being stolen; your reputation as a business would suffer and customers could go elsewhere.
