When it comes to protecting sensitive customer data and ensuring secure transactions, businesses must adhere to strict industry standards. One such standard is the Payment Card Industry Data Security Standard (PCI DSS), a set of requirements designed to ensure the secure handling and processing of credit card information.
To ensure compliance with these standards, businesses must undergo a PCI audit, a comprehensive assessment of their payment card processing system. In this article, we will explore what a PCI audit is, why it is important, and how you can get your business ready for a successful audit. So, if you want to know more about PCI audits and how they can benefit your business, keep reading!

What is a PCI Compliance Audit?
A PCI compliance audit is a detailed examination of a company’s adherence to the Payment Card Industry Data Security Standard (PCI DSS). The purpose of the audit is to assess whether the company’s processes, systems, and controls are in line with the requirements outlined by the PCI Security Standards Council.
The PCI DSS is a set of security standards established by major credit card companies to ensure the protection of cardholder data and prevent fraud. Any organization that handles, processes, or stores credit card information is required to comply with PCI DSS.
During a PCI compliance audit, a qualified auditor will assess the company’s policies, procedures, and technical controls to verify compliance with the PCI DSS requirements. This includes reviewing documentation, conducting interviews with relevant personnel, and performing technical tests to identify any potential vulnerabilities or weaknesses in the company’s security measures.
The audit process typically involves several steps, including a scoping review to determine the scope and objectives of the audit, a documentation review to assess the company’s policies and procedures, and a testing phase to evaluate the effectiveness of technical controls.
Once the audit is complete, the auditor will provide a detailed report outlining the findings and recommendations for remediation if any non-compliant areas are identified. This report is then used by the company to address any deficiencies and improve its security measures to ensure ongoing compliance with the PCI DSS.
Overall, a PCI compliance audit plays a critical role in helping companies maintain the security of cardholder data and protect against data breaches. By undergoing regular audits and taking necessary actions to address any compliance gaps, organizations can demonstrate their commitment to data security and build trust with customers, partners, and stakeholders.
Types of PCI Audits and Assessments
There are four main levels of PCI audits, each with its own set of criteria and requirements.- Level 1: This is the highest level of audit and is required for companies that process over 6 million transactions annually or have experienced a data breach. Level 1 audits require a comprehensive assessment of a company’s security measures, including network scans and penetration testing.
- Level 2: Companies that process between 1 and 6 million transactions annually fall under Level 2. This level requires an annual self-assessment questionnaire (SAQ) and quarterly network scans to ensure compliance with the PCI DSS.
- Level 3: Level 3 is for companies that process between 20,000 and 1 million transactions annually. Similar to Level 2, Level 3 requires an annual SAQ and quarterly network scans. However, Level 3 also requires an additional onsite assessment conducted by a Qualified Security Assessor (QSA).
- Level 4: The lowest level of audit, Level 4 is for companies that process fewer than 20,000 transactions annually. At this level, companies are required to complete an annual SAQ and may be subject to random network scans.
Stages of the PCI audit process
The first stage of the PCI audit process is the scoping phase. During this stage, the scope of the audit is determined, including which systems and processes are in scope for the assessment. It is essential to accurately define the scope to ensure that all relevant systems and processes are included in the audit.
The next stage is the gap analysis. This involves assessing the current security measures in place against the requirements outlined in the PCI DSS. Any gaps or vulnerabilities will be identified, and a plan can be developed to address these issues.
Once any gaps have been addressed, the next stage is the remediation phase. This phase involves implementing the necessary measures to bring the organization into compliance with the PCI DSS. This may include implementing new security controls, updating policies and procedures, and training employees on secure practices.
After the necessary remediation has occurred, the organization can move on to the assessment phase. During this stage, an approved Qualified Security Assessor (QSA) will conduct an assessment of the organization’s systems and processes to ensure compliance with the PCI DSS. The QSA will review documentation, conduct interviews, perform technical tests, and assess the overall security posture of the organization.
Following the assessment, the final stage is the reporting phase. The QSA will provide a report detailing the findings of the assessment, including any areas of non-compliance and recommended remediation actions. This report is typically submitted to the organization’s acquiring bank or payment card brand for review.
It is important to note that the PCI audit process is not a one-time event but an ongoing process. Organizations must regularly assess their compliance with the PCI DSS and implement any necessary remediation measures to maintain a secure payment environment. Regular audits are essential to ensure continued compliance and protect cardholder data.
What is PCI Readiness Assessment and Why it’s Important
Common Challenges and Solutions in PCI Audits
One of the most common challenges during a PCI audit is dealing with compliance gaps. These gaps may be the result of outdated technology, lack of employee training, or poor security controls. To address this challenge, organizations should conduct a thorough review of their current systems and processes to identify any potential compliance gaps. Once identified, a plan should be developed to remediate these gaps and bring the organization back into compliance. This may involve updating technology, implementing additional security measures, or providing training to employees.
Another challenge that organizations often face during a PCI audit is managing and securing cardholder data. This includes ensuring that data is encrypted, securely stored, and only accessed by authorized personnel. To address this challenge, organizations should implement strict access controls, regularly monitor their systems for any unauthorized access or activity, and establish procedures for securely storing and transmitting cardholder data.
Additionally, many organizations struggle with maintaining documentation and evidence of their compliance efforts. This is essential during a PCI audit, as auditors will need to review and validate the organization’s compliance measures. To address this challenge, organizations should establish a comprehensive documentation system that includes policies, procedures, and evidence of compliance. Regularly reviewing and updating this documentation will help ensure that it remains accurate and up-to-date.
Lastly, organizations often face challenges related to third-party service providers. These providers may handle cardholder data on behalf of the organization, making them a potential weak link in the security chain. To address this challenge, organizations should conduct due diligence when selecting third-party service providers, ensuring that they have appropriate security measures in place. Regularly reviewing and updating service provider agreements to include specific security requirements and conducting periodic audits of these providers can also help mitigate risks. After the Audit: Maintaining Ongoing Compliance.
