Merchants must scan computer systems at various intervals for Payment Card Industry Data Security Standard (PCI DSS), depending on their merchant type and other criteria.

Read our merchant data security sticky web page for further information and links.

PCI Security Standards Council maintains a list of certified scanning companies

Below is a select list of those I’ve had the most positive interaction with over the years.

Comodo CA Ltd
www.comodo.com HackerGuardian PCI Scanning Service

ControlScan
www.controlscan.com PCI 1-2-3

Digital Resources Group
www.drgsf.com DRG SecureScan

McAfee Inc.  McAfee Secure, formerly Hacker Safe (I knew Hacker Safe very well, but have had little experience with McAfee Secure)
www.mcafee.com

Qualys
www.qualys.com QualysGuard

This list does not infer the other companies would be less acceptable to work with, only that I’ve personally not dealt with the company or simply not had enough interaction to remember them. To protect your company from credit card processing fraud and the costly repercussions of it, all companies should have completed a PCI Compliance Certification whether you have standalone terminals or are connected to computers.
