While the PCI standard might seem like another snarl of red tape to companies already burdened with financial services industry regulations such as International Organization for Standardization (ISO) / International Electro technical Commission (IEC) 27002 and the Sarbanes-Oxley Act, the standard can actually simply your job enormously. It is so comprehensive and well designed that it can be seen as a compliance enabler for a broad set of industry regulations. And because privacy is a core concern for almost all business, PCI standard compliance supports your bottom line.
In fact, the PCI standard can actually become the central principle around which your overall governance and risk management strategy can be organized. By adopting the PCI standard as a best practice and aligning its security measures with your business processes, you will be likely see significant gains in efficiency and data security.
