Any business that accepts, transmits, or processes ACH (see what is ACH payment), credit card or eCheck payment information through its system needs to follow certain rules and regulations in order to keep that information as secure as possible. This is also why you need to use a good eCommerce payment gateway.

Dealing with sensitive customer data means that you’ll need a secure platform because any security breach that could make their data vulnerable can also affect your relationship with them and your business's overall reputation.

These regulations are referred to as the Payment Card Industry Data Security Standard (PCI DSS). Keep reading to learn more about PCI compliance and why your business needs to adhere to it.

This set of standards went into effect in September 2006. PCI is managed by a group of representatives from the major credit card companies MasterCard, Visa, Discover, American Express, and JCB. The group is called the PCI Security Standards Council. These companies also enforce PCI compliance to ensure that all credit card payments are as secure as possible. They are focused on both direct to consumer and B2B payments.

What Is PCI?

What does PCI stand for? It means the Payment Card Industry and it is used to control and regulate the security of credit card transactions. Since PCI stands for Payment Card Industry, the major credit card companies all give their input by managing the security standards council to uphold PCI meaning and security.

PCI Security and Standards

The PCI Security Standards Council (SSC) works to continuously monitor credit card payments and find new ways to beef up security around them. Without their regulations, it could be harder to protect financial information from cybersecurity threats that could steal your information or your customers’ information. The SSC also offers and provides valuable tools and resources that companies can use to measure their security framework and secure eCommerce accounting data. Types of resources they provide include:

  • Self-assessment questionnaires to measure organizations’ compliance
  • List of approved vendors
  • Secure software program guide
  • PIN security requirements

Essentially, the SSC’s goal is to create a community that can work together to help protect and secure the data needed to process and transmit the incredible amount of credit card transactions that happen every day. They provide education and awareness so that all stakeholders in the process know what needs to be done and how to implement it. If you are not sure of the best ways to implement PCI security standards, you may want to utilize a payment processing provider who can easily offer that capability to your business.

PCI Compliance

Following PCI compliance is vital for any business, as it guarantees secure transactions and thus increases trust in your organization. Customers are less likely to use a credit card online if your payment portal is not guaranteed to be secure.

What exactly is PCI compliance? It involves following a set of rules and regulations that the SSC has set forth and continues to update as security threats grow and evolve. Benefits of PCI compliance include:

  • An increase in customer trust means that customers are more likely to come back for another transaction or even set up recurring transactions in the subscription payment model
  • Helps boost your organization’s reputation with customers, vendors, and other businesses
  • Helps to stop potential security breaches that could steal important customer data
  • Can also help you with meeting compliance for other regulations like SOX, HIPAA, and GDPR
  • Assists you in better understanding the meaning of PCI compliance

To meet PCI compliance requirements your IT team may have to take some extra steps and follow the resources provided by the SSC. 

PCI Compliance Checklist

There are certain items you have to have in order to establish PCI compliance as a business. This checklist of items is established by the SSC and following them is important in order to remain a trusted entity within the PCI compliance network. This checklist includes things such as:

  • Maintain and use firewalls
  • Properly protect passwords
  • Safeguard data for cardholders
  • Provide encryption for transmitting data
  • Keep and constantly update anti-virus software
  • Update all software involved regularly
  • Make sure cardholder data is only accessed by certain staff members
  • Give each staff member unique credentials
  • Ensure any card data that is written down and stored is in a restricted area
  • Keep up with who accesses the data
  • Routinely check for system vulnerabilities
  • Document all of your processes

By updating all firewalls and other involved software continuously, you’re ensuring the most secure environment possible. Sometimes, software companies will issue a patch to fix a problem they’ve found. This could help prevent hackers from accessing any vulnerabilities. You also need to make sure only certain staff members have access to cardholder data. This keeps it secure as well, as not every single employee should or needs to know credit card numbers. Plus, it’s much easier to trace who accessed it if or when a problem does arise. Make sure the eCommerce software you use is up to date and safe from intrusion.

PCI Compliance Levels

Meeting compliance is important, but you also need to make sure you’re following compliance for the level of your organization. For example, level 1 compliance requires an external audit, while levels 2-4 are able to complete a self-assessment questionnaire. There are four different levels of PCI compliance and those are based on the number of transactions your company handles each year. The PCI compliance levels are:

  • Level 1: Companies that process more than 6,000,000 transactions each year
  • Level 2: Companies that process 1,000,000 to 6,000,000 transactions yearly
  • Level 3: Companies that process 20,000 to 1,000,000 transactions annually
  • Level 4: Companies that process fewer than 20,000 transactions per year


PCI is used a lot to talk about this, but the full term is actually Payment Card Industry Data Security Standard. So, you may see “PCI DSS” when you’re learning more about establishing PCI compliance.

PCI DSS Meaning

PCI DSS stands for “Payment Card Industry Data Security Standard.” It is the name for the standards set forth by the SSC, if you see it and wonder what PCI DSS is. Following these standards makes it easier for your business to accept and process credit card payments either ad hoc or using a net 30 payment plan. Not meeting compliance may make it tough for you to conduct business.

PCI DSS Compliance

Failing to meet PCI DSS requirements can have severe complications for your organization. Along with losing consumer trust, your organization could also risk its financial information, as it would be easily accessible to hackers who can turn around and sell that to the highest bidder. Failing to keep customer data secure may also lead to lawsuits or other legal action against your company. If your company is publicly traded, you could see a substantial dip in the worth of stock prices as well.
