PCI DSS Audit: Everything You Need to Know to Keep Your Company Secure

If your company handles credit card transactions, a PCI DSS audit is essential. Cybercrime Magazine stated that cybercrime is projected to cost the world $10.5 trillion annually by 2025. This statistics implies that your payment systems must meet the Payment Card Industry Data Security Standard (PCI DSS).

A PCI DSS audit assesses whether you’re meeting the standards designed to protect cardholder data. It showcases how seriously your company takes customer trust. Knowing what to expect can make or break your compliance journey. This article will discuss everything you need to know about the PCI DSS audit. Let’s get started. 

‍

1. What is a PCI DSS Audit?

A PCI DSS audit is a formal evaluation of how well your company protects cardholder data. It checks whether your systems, processes, and security practices meet the PCI DSS requirements.

If you're processing, storing, or transmitting card data, you're expected to comply with PCI DSS. And the audit? That’s the moment of truth. Depending on your transaction volume and classification level, this could mean:

• A Self-Assessment Questionnaire (SAQ)
• A Report on Compliance (ROC)

Take the 2019 breach at Wawa, for example. The company suffered a major compromise of cardholder data due to malware on point-of-sale systems, affecting over 30 million customers. Investigations revealed gaps in PCI DSS compliance, highlighting what can go wrong when the audit process isn’t strong enough.

2. What Does a PCI DSS Audit Involve?

A PCI DSS audit is designed to assess whether your company is doing enough to protect cardholder data. about proving that your systems, policies, and workflows meet the security standards set by the PCI Security Standards Council.

Depending on your business size and transaction volume, you'll either complete a Self-Assessment Questionnaire (SAQ) or undergo a full Report on Compliance (ROC):

• If you're a lower-level merchant, the SAQ lets you evaluate your own environment by answering a structured set of yes/no questions.
• If you're processing large volumes or storing sensitive data, you’ll need a ROC. It’s an in-depth review conducted by a Qualified Security Assessor (QSA) who will examine your systems, interview staff, and verify documentation.

In most cases, especially with ROCs, an external auditor will guide the process. But even if you’re eligible for self-assessment, don’t treat it lightly. The PCI DSS audit reflects your company’s commitment to customer data security.

3. Who Needs a PCI DSS Audit?

It doesn’t matter if you're a multinational retailer or a small SaaS provider. The moment you handle payment card information, you fall under the scope of PCI DSS. The level of scrutiny depends on your annual transaction volume and the card brands you work with:

• Level 1 merchants who are processing over 6 million transactions annually must undergo a full audit and submit a Report on Compliance.
• Smaller merchants may only need to complete a Self-Assessment Questionnaire, but that still requires accuracy and accountability.

As Bob Russo, former General Manager of the PCI Security Standards Council, once put it:

“Security is not about compliance—it’s about doing the right thing to protect your customers and your brand.”

Whether you’re processing thousands or millions of payments, the responsibility is the same: prove that your environment is secure enough to handle sensitive data. The audit is how you demonstrate that trust.

4. What Are the 12 PCI DSS Requirements?

When preparing for a PCI DSS audit, you’ll need to show that your company meets 12 core requirements. They’re grouped into logical categories that address every angle of cardholder data protection, from infrastructure to policy enforcement.

Here’s how they break down:

Build and Maintain a Secure Network and Systems

1. Install and maintain a firewall to protect cardholder data.
2. Avoid using vendor-supplied defaults for passwords and other security parameters.

Protect Cardholder Data

3. Protect stored cardholder data using encryption or other strong controls.
4. Encrypt transmission of cardholder data across public networks.

Maintain a Vulnerability Management Program

5. Use anti-virus and anti-malware software on all systems.
6. Develop and maintain secure systems through regular patching and secure coding practices.

Implement Strong Access Control Measures

7. Restrict access to cardholder data on a need-to-know basis.
8. Assign unique IDs to each person with computer access.
9. Restrict physical access to cardholder data environments.

Regularly Monitor and Test Networks

10. Track and monitor all access to network resources and cardholder data.
11. Test security systems and processes regularly to catch vulnerabilities early.

Maintain an Information Security Policy

12. Create and maintain a policy that addresses information security for all staff.

These requirements cover everything from your network perimeter to employee awareness. During a PCI DSS audit, you’ll need to demonstrate not just that these measures exist but that they’re being enforced consistently across your environment.

5. How Do You Prepare for a PCI DSS Audit?

Before a PCI DSS auditor steps in, you should already know what they’re going to find. The more clarity you have about your systems, controls, and processes, the smoother the audit will be.

Start by conducting an internal gap assessment. Use the PCI DSS Self-Assessment Questionnaire (SAQ) as a guide to walk through each of the 12 requirements. Evaluate whether your existing controls meet the standard or fall short. Identify where sensitive cardholder data lives, who can access it, and how it's protected. You’ll also need to gather critical documentation:

• Network diagrams
• Data flow maps
• Change management logs
• Access control records
• Security policy documents

A surprising number of companies stumble here. In fact, a 2023 Verizon Payment Security Report found that only 43.4% of global organizations were fully PCI DSS compliant during their interim validation. This is a clear sign that many underestimate the importance of ongoing readiness.

To avoid that, treat compliance as a continuous process, not a one-time task. Perform regular vulnerability scans, keep software patched, and train your employees to recognize security risks. The sooner you spot weaknesses, the easier they are to fix.

‍

6. What Are the Consequences of Failing the PCI DSS Audit?

If your company is found non-compliant, you could face hefty fines from payment processors, ranging from $5,000 to $100,000 per month depending on the severity and duration of non-compliance. These penalties often compound with additional charges for forensic investigations, chargebacks, and remediation.

But the financial impact is only part of the story. The reputational fallout can be far worse. Customers, partners, and stakeholders lose trust quickly when a data breach is traced back to ignored security standards.

One of the most well-known examples is the Target breach in 2013, where attackers stole over 40 million credit and debit card records. While the root cause was multi-faceted, investigators highlighted PCI DSS violations, including failure to properly segment networks and monitor third-party vendor access.

The aftermath? Target paid over $162 million in breach-related costs, excluding the long-term damage to its brand.
