PCI Compliance Checklist


What is PCI Compliance?

The Payment Card Industry Data Security Standard (PCI DSS) is a set of security standards designed to ensure that all businesses who accept, process, store or transmit credit card information do so in a secure environment.

The Payment Card Industry Security Standards Council (PCI SSC), an independent body that was created by the major payment card brands (Visa, MasterCard, American Express, Discover and JCB) was launched in 2006 in order to manage the Payment Card Industry (PCI) security standards with a focus on improving payment account security throughout the transaction process. 

Failure to meet the requirements of PCI DSS compliance means you may be subject to huge fines which can ultimately have a detrimental affect on your business. 

Although this all may sound like a great deal of work - the benefits are significant:

  • Reduces the risk of data breaches

  • Helps you avoid expensive fines

  •  Protects customers’ sensitive data

  • Simplifies global regulatory compliance

  • Provides peace of mind for everyone

How do PCI Standards Work?

If your business accepts payment cards with any of the five members of the PCI SSC credit card brands (American Express, Discover, JCB, Mastercard, and Visa), then you are required to be PCI compliant.

The level of compliance you must adhere to depends on the number of transactions you process annually. For example, if you make a high volume of transactions (as described below) you are required to work with internal security assessors (ISAs), qualified security assessors (QSAs), and PCI-approved scan vendors (ASVs).

There are four different levels of compliance; these levels stipulate the requirements for which sellers are responsible. 

PCI compliance levels

  • Level 1: Merchants that process over 6 million card transactions annually

  • Level 2: Merchants that process 1 to 6 million transactions annually

  • Level 3: Merchants that process 20,000 to 1 million transactions annually

  • Level 4: Merchants that process fewer than 20,000 transactions annually

Every level has its own set of requirements to provide, including annual reports, network scans, filling out forms, and answering questionnaires.

Most businesses (small and medium) will generally fall under the level 4 category, however, it’s worth checking

Not only will your business face its own penalties, it’s likely you’ll have to compensate your customers as well for things like credit card monitoring and identity theft insurance. 

Not only that, the damage to your business’ reputation and loss of customer trust will be impacted potentially having a huge impact on profits and the growth.

As already stated, there are serious consequences for not being PCI compliant.
