In today’s fast-paced digital landscape, where data breaches have become alarmingly commonplace, safeguarding sensitive information has never been more critical. Therefore, organizations handling payment card transactions must adhere to stringent security standards to ensure the protection of customer data. In this blog, we will explore the intricacies of the PCI Attestation of Compliance (AoC), breaking down its components, and understanding the processes involved. So let’s explore how businesses can strengthen their security posture, establish trust with their customers, and ensure the longevity and success of their operations.

What is a PCI AoC?

What is a PCI AoCWhen it comes to securing payment card transactions, PCI Attestation of Compliance (AoC) plays a pivotal role. Additionally, AoC serves as tangible evidence that an organization has successfully undergone a comprehensive assessment of its payment card environment, demonstrating compliance with the Payment Card Industry Data Security Standard (PCI DSS). It showcases the organization’s commitment to maintaining a secure environment for processing, transmitting, and storing payment card data. In essence, AoC is a crucial document that validates adherence to PCI DSS requirements, instilling confidence in customers, auditors, and stakeholders.

What Is The Difference Between RoC and AoC PCI?

Understanding the distinction between Report on Compliance (RoC) and AoC is essential in comprehending the PCI compliance landscape. While both serve as key elements of PCI DSS validation, they differ in their scope and purpose.

The RoC, or Report on Compliance, is an in-depth assessment conducted by a Qualified Security Assessor (QSA). It involves a comprehensive evaluation of an organization’s security controls, processes, and policies. The RoC provides an extensive analysis of compliance with each PCI DSS requirement, offering detailed insights into vulnerabilities, recommendations, and areas of improvement.

On the other hand, the AoC, or Attestation of Compliance, is a concise document that summarizes the findings of the RoC. The document summarizes the organization’s compliance status, including assessment scope, implemented controls, and achieved a level of compliance. The AoC serves as proof of compliance, providing stakeholders, auditors, and potential business partners with a quick and easily understandable snapshot of the organization’s adherence to PCI DSS requirements.

Who Needs An Attestation of Compliance?

Obtaining an Attestation of Compliance (AoC) is essential for various entities involved in payment card transactions. The following groups typically require an AoC:

  • Merchants: Businesses that accept payment cards, whether online or in physical stores, are obligated to comply with the Payment Card Industry Data Security Standard (PCI DSS). Merchants of all sizes, from small retailers to large enterprises, must obtain an AoC to demonstrate their commitment to safeguarding cardholder data.
  • Service Providers: Third-party service providers that handle payment card data on behalf of merchants, such as payment processors, hosting providers, or software developers, also need to comply with PCI DSS. These service providers must undergo assessments and obtain an AoC to assure their clients of their security measures.
  • Financial Institutions: Banks, credit card issuers, and other financial institutions that process payment card transactions are subject to PCI DSS compliance. These institutions must undergo rigorous assessments and obtain an AoC to instill confidence in their customers and maintain the security of cardholder data.
  • Acquirers: Acquiring banks or financial institutions that establish relationships with merchants to facilitate payment card transactions also have a responsibility to ensure PCI DSS compliance. Acquirers must verify that the merchants they onboard maintain valid AoCs to mitigate the risk associated with processing payments.
  • Regulators and Auditors: Regulatory bodies and auditors may require organizations to provide evidence of compliance with PCI DSS. They rely on the AoC as a critical document to assess an organization’s adherence to security standards and regulatory requirements.

The Importance of PCI Attestation of Compliance (AoC)

  • Regulatory Compliance: Compliance with the Payment Card Industry Data Security Standard (PCI DSS) is a requirement enforced by card brands and regulatory bodies. Therefore, having an AoC demonstrates an organization’s adherence to these standards, avoiding penalties and legal implications.
  • Data Security: AoC signifies an organization’s commitment to data security and protecting sensitive cardholder information.
  • Reputation and Trust: A valid AoC enhances an organization’s reputation as a trustworthy entity for handling payment card data. Therefore, it shows a dedication to maintaining high-security standards and positions the organization as a reliable partner for customers, stakeholders, and financial institutions.
  • Business Opportunities: Holding a current AoC opens doors to collaboration, enabling organizations to pursue new business opportunities and partnerships.
  • Risk Mitigation: Compliance with PCI DSS and possessing an AoC helps mitigate the risk of data breaches and cyberattacks. By implementing the required security controls, organizations can protect themselves and their customers from potential financial losses and reputational damage.
  • Customer Confidence: Displaying a valid AoC reassures customers that we handle their data responsibly, fosters trust, and ensures their continued loyalty.

How Can You Obtain a PCI Attestation?

How Can You Obtain a PCI AttestationObtaining a PCI Attestation of Compliance (AoC) requires a systematic approach and adherence to specific processes. Here are the key steps involved in obtaining a PCI AoC:

  • Determine the Scope: Identify the scope of your organization’s payment card environment, including the systems, processes, and networks that handle cardholder data.
  • Assess Security Controls: Conduct a thorough assessment of your organization’s security controls against the requirements outlined in the Payment Card Industry Data Security Standard (PCI DSS). For an independent evaluation, organizations can engage a Qualified Security Assessor (QSA) to carry out this assessment or conduct it internally.
  • Remediate Vulnerabilities: Address any vulnerabilities or gaps identified during the assessment process. Implement necessary security measures, policies, and procedures to align with the PCI DSS requirements and mitigate risks to cardholder data.
  • Conduct Validation: Depending on the size and complexity of your organization, you may need to complete a Self-Assessment Questionnaire (SAQ) or engage a QSA to perform an on-site assessment.
  • Submit Compliance Documentation: Prepare and submit the required compliance documentation, which may include the completed SAQ or the Report on Compliance (RoC) if assessed by a QSA. These documents serve as evidence of your organization’s compliance with PCI DSS.
  • Obtain Attestation of Compliance: Once your compliance documentation has been reviewed and approved, your organization will receive the PCI Attestation of Compliance (AoC). The AoC serves as a formal acknowledgment of your organization’s adherence to PCI DSS requirements.
  • Maintain Ongoing Compliance: PCI compliance is not a one-time event; it requires continuous effort.  By regularly assessing and validating your security controls, monitoring for new vulnerabilities, and implementing updates and improvements to maintain ongoing compliance.

How Long Is An Attestation of Compliance (AoC) Valid?

The validity period of an Attestation of Compliance depends on several factors. Firstly, it varies based on the specific payment card brand requirements. Additionally, the type of AoC obtained and the results of the compliance assessment play a role in determining the validity.

Typically, an AoC is valid for one year from the date of issuance. However, it’s crucial to note that organizations must actively maintain ongoing compliance, as they must sustain compliance throughout the validity period and beyond. Regular assessments and updates are necessary to ensure continuous adherence to the Payment Card Industry Data Security Standard (PCI DSS) requirements.


In conclusion, obtaining a PCI Attestation of Compliance (AoC) is a vital step for organizations involved in payment card transactions. It ensures regulatory compliance and commitment to data security, building reputation, and trust, and opening doors to business opportunities. Additionally, mitigates risks and instills customer confidence by proactively pursuing PCI compliance, protecting sensitive data, and strengthening security posture. Through this, organizations establish themselves as reliable partners in payment card transactions, emphasizing their commitment to data protection.
