You can hire any consultant or professional you want to help you with the preparations for PCI DSS.

There are many domestic and international companies that offer their services in gap analysis, PCI preparation, audit preparation, firewall compliancy, policy compliancy and more.

If you want to undergo a certified PCI DSS audit you can only use a company deemed as a Qualified Security Assessor (QSA).

In case you are required to undergo quarterly network scans you can only use a company certified as an Approved Scanning Vendor (ASV).

GRsee is a Qualified Security Assessor. We offer our clients a wide range of services that include Gap analysis, PCI preparation projects and PCI audits. We also provide network scans conducted by an ASV as part of our full PCI packages.
