System Testing
There are many aspects to IT system testing, many depend upon the necessary outcome. If you are looking to confirm you have met some regulatory standard or compliance requirement, then you should choose the testing assocaited with that standard (albeit PCI, UK Accreditation, GSCx or CDS).
If you have never been tested or are seeking testing with a wide remit, we would recommend a more general IT Security Health Check or Vulnerability Analysis.
