In a significant move aimed at simplifying compliance requirements and streamlining merchant classifications, Visa has recently announced the consolidation of its Merchant Levels 3 and 4 into a single category, now referred to as Level 3. This change is part of Visa’s ongoing efforts to adapt to the evolving payment landscape and make compliance more accessible for smaller merchants. Let’s dive into what this means for businesses and how it impacts the broader merchant ecosystem.

---

What Are Merchant Levels?

Merchant levels are classifications used by payment card brands like Visa to determine the compliance requirements for businesses that accept card payments. These levels are primarily based on the annual transaction volume processed by a merchant and the type of transactions (e.g., e-commerce, in-store).Previously, Visa categorized merchants into four levels:

• Level 1: Large merchants processing over 6 million Visa transactions annually.
• Level 2: Merchants processing 1 to 6 million Visa transactions annually.
• Level 3: Merchants processing 20,000 to 1 million Visa e-commerce transactions annually.
• Level 4: Merchants processing fewer than 20,000 Visa e-commerce transactions annually or up to 1 million transactions across all channels.

The recent change eliminates Level 4 by merging it with Level 3, creating a unified category for smaller merchants.

---

Why Did Visa Make This Change?

The decision to combine Levels 3 and 4 reflects Visa’s commitment to simplifying compliance requirements for merchants. By consolidating these levels, Visa aims to:

1. Reduce Complexity: Many merchants found the distinction between Levels 3 and 4 confusing, especially when determining their compliance obligations. Merging these levels simplifies the classification process.
2. Streamline Compliance: Smaller merchants often lack the resources to navigate complex compliance requirements. A unified Level 3 category ensures that these businesses have a clearer understanding of their obligations.
3. Enhance Security Standards: By aligning smaller merchants under a single category, Visa can enforce consistent security measures, reducing vulnerabilities in the payment ecosystem.

---

What Does This Mean for Merchants?

For merchants previously classified as Level 4, this change brings some adjustments to their compliance requirements. Here’s what businesses need to know:

1. Unified Compliance Obligations: Merchants now classified under the new Level 3 will need to adhere to the compliance standards previously associated with Level 3. This includes completing the appropriate Self-Assessment Questionnaire (SAQ) and, in some cases, undergoing vulnerability scans.
2. Focus on E-Commerce Transactions: The new Level 3 category continues to emphasize e-commerce transactions, which are more susceptible to fraud. Merchants processing between 20,000 and 1 million Visa e-commerce transactions annually will fall under this category.
3. Improved Support for Small Businesses: Visa’s consolidation effort is expected to provide smaller merchants with better resources and guidance to achieve compliance, ensuring they can protect customer data effectively.

---

Implications for the Payment Ecosystem

This change is not just about simplifying compliance—it’s also about strengthening the overall security of the payment ecosystem. By unifying smaller merchants under a single category, Visa can:

• Standardize Security Measures: Consistent compliance requirements across a broader range of merchants help reduce gaps in security.
• Encourage Adoption of Best Practices: Smaller merchants often struggle with implementing robust security measures. The new Level 3 classification ensures they are held to higher standards, fostering a more secure payment environment.
• Support Growth in E-Commerce: With the rise of online shopping, e-commerce transactions have become a focal point for fraud prevention. Visa’s updated classification reflects this shift and prioritizes the protection of online transactions.

---

What Should Merchants Do Next?

If your business was previously classified as a Level 4 merchant, it’s essential to review the updated compliance requirements for Level 3. Here are some steps to take:

1. Consult Your Acquiring Bank or Processor: They can provide specific guidance on how the changes impact your business and what steps you need to take to remain compliant.
2. Complete the Appropriate SAQ: Ensure you are using the correct Self-Assessment Questionnaire for your transaction volume and business type.
3. Implement Security Measures: Focus on PCI DSS compliance, including encryption, tokenization, and regular vulnerability scans, to protect customer data.
4. Stay Informed: Keep an eye on updates from Visa and other card brands to ensure you remain compliant with evolving standards.

---

Conclusion

Visa’s decision to merge Merchant Levels 3 and 4 into a single Level 3 category is a welcome change for many businesses. By simplifying compliance requirements and focusing on consistent security standards, Visa is making it easier for smaller merchants to navigate the complexities of payment security. For merchants, this is an opportunity to enhance their security posture and build trust with customers in an increasingly digital world.

Two encryption methods stand out when securing payment card data: Point-to-Point Encryption (P2PE) and End-to-End Encryption (E2EE). Both methods aim to protect sensitive information, yet they vary significantly in their implementation, validation processes, and ability to limit exposure. It is essential for businesses to grasp these distinctions in order to improve security and uphold PCI DSS compliance.

What is P2PE?

Point-to-Point Encryption (P2PE) is a robust encryption standard explicitly designed for the payment industry and is validated by the Payment Card Industry Security Standards Council (PCI SSC). P2PE ensures that cardholder data is encrypted at the point of interaction—whether the card is swiped, dipped, or tapped—and remains encrypted until it reaches a secure decryption environment.

Merchants using P2PE solutions are relieved of the responsibility of managing encryption keys, as the encryption provider assumes this role. These solutions undergo rigorous testing and validation by the PCI SSC to ensure compliance with stringent security standards. Furthermore, merchants receive a P2PE Instruction Manual (PIM), which provides detailed guidance on securely managing devices and encryption settings.

Key Benefits of P2PE:

1. PCI Scope Reduction: By encrypting card data, P2PE minimizes the scope of PCI DSS compliance, as sensitive data is never transmitted in a readable form within the merchant’s environment.
2. Certified Security: PCI SSC validation ensures that P2PE solutions meet high-security standards.
3. Streamlined Audits: Merchants benefit from simplified auditing processes with clear guidelines.

What is E2EE?

End-to-End Encryption (E2EE), on the other hand, is a more flexible encryption methodology that protects data from the point of capture to its final destination. Unlike P2PE, E2EE is not a PCI SSC-validated standard and does not inherently offer the same benefits of scope reduction. This lack of standardization means that E2EE implementations can vary widely, leading to potential security inconsistencies.

E2EE also places a higher burden on merchants, who are often responsible for managing encryption keys and ensuring proper implementation. Additionally, E2EE solutions may involve intermediate nodes where encryption and decryption occur, increasing the attack surface and potential vulnerabilities.

Key Characteristics of E2EE:

1. Flexibility: E2EE can be applied to diverse use cases beyond payment processing, such as secure email, file sharing, and messaging.
2. No Standard Validation: Without PCI SSC validation, E2EE solutions may lack consistency in terms of security and compliance.
3. Merchant Responsibility: Merchants must manage encryption keys and ensure secure implementation, which can be resource-intensive.

Key Differences between P2PE and E2EE

1. Validation and Certification:
   • P2PE: Fully validated by the PCI SSC, providing assurance of compliance with rigorous security standards.
   • E2EE: Not validated by the PCI SSC, meaning it does not automatically meet PCI DSS scope reduction requirements.
2. PCI DSS Scope Reduction:
   • P2PE: Significantly reduces PCI DSS compliance scope by ensuring data remains encrypted from the point of interaction to a secure decryption environment.
   • E2EE: Does not guarantee scope reduction due to its lack of standardization.
3. Encryption Key Management:
   • P2PE: The solution provider manages encryption keys, reducing merchant responsibility and liability.
   • E2EE: Merchants often retain control over encryption keys, increasing their security responsibilities.
4. Intermediate Nodes:
   • P2PE: Data remains encrypted throughout its journey without intermediate decryption points.
   • E2EE: May involve intermediate nodes where encryption and decryption occur, increasing the attack surface.
5. Use Cases:
   • P2PE: Primarily used for securing payment card transactions.
   • E2EE: Versatile and used for various applications, including messaging, email, and file sharing, in addition to payment processing.

Common Pitfalls of E2EE

While E2EE offers unmatched flexibility, it comes with inherent challenges:

• Lack of Standardization: Without PCI SSC validation, E2EE solutions can vary in quality and security.
• Increased Merchant Liability: Merchants must manage encryption keys and ensure correct implementation, which can be complex and costly.
• Potential Vulnerabilities: The use of intermediate nodes in some E2EE implementations can introduce additional security risks.

Why P2PE is Often the Preferred Choice

For businesses prioritizing payment security and compliance, P2PE is typically the superior choice. Its PCI SSC validation ensures a high level of security, reduces PCI DSS scope, and simplifies compliance processes. P2PE’s standardized approach offers peace of mind, as merchants do not have to manage encryption keys or worry about vulnerabilities introduced by intermediate nodes.

However, E2EE remains valuable for organizations with specific needs, particularly those that protect non-payment data such as emails or file transfers. In such cases, partnering with experienced security professionals is critical to ensure proper implementation and risk management.

Conclusion

While both P2PE and E2EE play essential roles in securing sensitive data, they serve different purposes and cater to distinct needs. P2PE, with its PCI SSC validation and scope reduction capabilities, is the gold standard for securing payment card transactions. In contrast, E2EE offers flexibility but demands more from merchants regarding security and compliance.

Ultimately, the choice between P2PE and E2EE depends on your organization’s specific requirements, risk appetite, and compliance obligations. For businesses focused on payment security and PCI DSS adherence, P2PE is the recommended solution. However, when implemented correctly, E2EE can be a viable option for broader data protection needs.

As the cybersecurity landscape continues to evolve, businesses and assessors turn to innovative technologies to ensure compliance with industry standards. One such innovation is the integration of Artificial Intelligence (AI) into Payment Card Industry (PCI) assessments. The recently released guidelines from the PCI Security Standards Council (PCI SSC) outline a structured and secure approach to incorporating AI into PCI assessments, balancing efficiency and the critical need for human oversight.

What does this mean for assessors and businesses? Let’s examine the highlights of the March 2025 release of the “Integrating Artificial Intelligence in PCI Assessments—Guidelines, Version 1.0.”

AI: A Tool, Not a Replacement

The guidelines’ first and most important takeaway is that AI cannot replace human assessors. While AI can streamline tasks such as document reviews, data analysis, and report generation, final compliance decisions and judgments must always rest with human assessors. AI is a powerful tool for enhancing efficiency, reducing manual effort, and improving accuracy. However, it’s essential to remember that the responsibility for the assessment’s outcomes lies with the lead assessor and their team.

Key Tasks AI Should NOT Perform:

• Making final compliance decisions.
• Interpreting complex or nuanced requirements.
• Authorizing the release of assessment findings or reports.
• Conducting on-site evaluations.

In short, AI is here to assist, not to take over.

Benefits of AI in PCI Assessments

The PCI SSC guidelines highlight several areas where AI can make PCI assessments faster and more effective:

1. Reviewing Artifacts
   AI tools can automate the review of large volumes of documents, such as policies, network diagrams, and logs, pinpointing inconsistencies or missing information. For example, AI can parse thousands of logs to identify compliance issues in a fraction of the time it would take a human assessor.

   However, assessors must validate AI findings to ensure accuracy and reliability. Human oversight is critical to catching false positives or biases in AI-generated results.

2. Creating Work Papers
   AI can help organize data, provide preliminary analysis, and suggest areas for further investigation. This reduces the potential for human error and allows assessors to focus on the most critical aspects of the assessment.

   Still, qualified professionals must validate all AI-generated work papers to ensure they meet the required standards.

3. Facilitating Remote Interviews
   AI can streamline remote interviews by scheduling, transcribing conversations, and summarizing key points. This improves efficiency while maintaining data security and transparency. However, assessors must ensure that transcriptions and summaries are accurate and comply with data privacy regulations.
4. Assisting with Final Assessment Reports
   AI tools can suggest wording, summarize findings, and structure content according to PCI SSC templates. This can make reports more accessible to stakeholders. However, lead assessors must review and approve all AI-generated content, ensuring it reflects the assessment’s findings accurately.

Transparency and Client Communication

Clear communication with clients is essential when using AI in PCI assessments. Assessors must inform clients about how AI will be used, what tasks it will perform, and how their data will be handled.

Best Practices for Transparency:

• Declare AI usage and obtain client consent.
• Explain how human assessors will validate AI findings.
• Share data handling and security practices specific to AI processes.
• Keep clients informed of any changes in AI usage during the assessment.

Transparency builds trust and reassures clients that their data is handled securely and ethically.

Challenges and Limitations of AI

While AI offers many benefits, it also comes with challenges that assessors must address:

1. Potential for Errors

AI systems can produce false positives, misunderstand complex findings, or generate generic content that overlooks key details.

2. Bias in AI Outputs

AI tools must be regularly checked for biases in their algorithms to ensure fair and accurate results.

3. Ethical and Legal Considerations

AI must be used responsibly, strictly adhering to data privacy and security regulations. Assessors must ensure that sensitive client data is not used to train AI systems unless explicitly authorized.

Guidelines for Responsible AI Use

To ensure the safe and effective integration of AI into PCI assessments, the PCI SSC guidelines recommend the following:

1. Documented Policies and Procedures

Assessment companies should establish clear policies for AI usage, covering everything from tool selection to validation processes.

2. Validation of AI Outputs

All AI-generated outputs must undergo rigorous quality assurance (QA) processes, including cross-referencing with raw assessment data and manual reviews.

3. Data Security and Privacy

AI systems must comply with strict data handling protocols, ensuring client information is securely stored and not used for unauthorized purposes.

4. Continuous Improvement

AI tools should be regularly updated to reflect changes in PCI standards and improve accuracy over time.

The Role of Human Oversight

Ultimately, the success of AI in PCI assessments depends on human oversight. Assessors must take responsibility for the quality and accuracy of AI-generated findings and ensure they align with PCI standards and industry best practices.

The PCI SSC guidelines emphasize that AI is a tool to enhance human expertise—not to replace it. By combining the speed and efficiency of AI with the critical thinking and judgment of human assessors, PCI assessments can reach new levels of accuracy and reliability.

Conclusion: Embracing Innovation with Care

Integrating AI into PCI assessments marks an exciting step forward for the cybersecurity industry. By following the PCI SSC guidelines, assessors can leverage AI to streamline processes, reduce manual effort, and improve the quality of their assessments—all while maintaining the highest standards of security and compliance.

As the industry continues to innovate, the key to success will be finding the right balance between technology and human expertise. With AI as a powerful ally, assessors can stay ahead of the curve and ensure that PCI assessments remain a cornerstone of payment security in an ever-evolving digital landscape.

Are you ready to embrace the future of PCI assessments? Let AI help you work smarter—not harder—while keeping compliance and security at the forefront.
