The Payment Card Industry Data Security Standard (PCI DSS) underwent a major update in March 2022. Following this, a limited revision, PCI DSS 4.0.1, was introduced to refine and enhance the standard’s usability.
This update incorporates community feedback and includes several corrections and clarifications to improve the effectiveness of the standard for organizations that process, store, or transmit cardholder data and sensitive authentication data.
This guide will simplify the changes made in PCI DSS 4.0.1 and explain what they mean for your organization, focusing on practical concerns for CEOs.
What is PCI DSS 4.0.1?
PCI DSS 4.0.1 is a limited revision addressing stakeholder feedback since the publication of v4.0. This update reflects a continuous effort to enhance payment account data security and promote the adoption of consistent data security measures globally.
As a limited revision, PCI DSS v4.0.1 does not introduce major changes, such as adding or removing requirements. Instead, it includes corrections to formatting, typographical errors, and clarification of some requirements and guidance.

How do the latest changes to PCI DSS affect my business?
The latest changes in PCI DSS 4.0.1 primarily focus on clarifying existing requirements, enhancing guidance, and correcting minor errors from the previous version.
For businesses that handle cardholder data, these updates mean that while no major new requirements have been introduced, there may be adjustments needed to align with the clarified expectations. This could involve updating security policies, retraining staff, or fine-tuning technical controls to meet the refined guidelines.
The changes in the PCI DSS latest version aim to make compliance more straightforward, but they also reinforce the importance of maintaining rigorous data security standards. Failure to adapt to these updates could expose your business to unnecessary risks, including potential data breaches or non-compliance issues.
Is it mandatory to update to the latest version and what are the consequences of not doing so?
Yes, it is mandatory for organizations to transition to PCI DSS 4.0.1 by December 31, 2024. After this date, the previous version (v4.0) will be retired, and v4.0.1 will be the only active standard.
Failure to update to the PCI DSS latest version could result in non-compliance with PCI DSS requirements, which may lead to penalties, including fines imposed by payment card networks or acquirers.
Additionally, non-compliance can result in increased scrutiny during audits, higher transaction fees, or even the suspension of the ability to process card payments. Staying up-to-date with the latest standards is not only crucial for maintaining compliance but also for ensuring that your business remains secure against evolving threats.
PCI DSS 4.0.1 changes at a glance
All changes in PCI DSS 4.0.1 fall into two categories:
1. Clarification or guidance
Updates to wording, explanations, definitions, and additional guidance to increase understanding or provide further information on specific topics.
2. Structure or format
Reorganization of content, such as combining, separating, or renumbering requirements to better align content.
The changes in detail
1. Correcting or updating wording or formatting
PCI DSS 4.0.1 includes corrections for typographical and minor errors to improve the readability and effectiveness of the standard. For example, the phrase “impact the security of the CDE (Cardholder Data Environment)” in v4.0 has been changed to “impact the security of cardholder data and/or sensitive authentication data” in v4.0.1. Additionally, Testing Procedures have been updated to align with the updated Requirement wording.
2. Updating appendices and removing templates
Several changes have been made around the Glossary or Appendix G. Definitions included in both the Guidance and the Glossary have been removed from the Guidance, which now refers to the Glossary instead. There are also additional references to newly defined glossary terms. In Appendix E, the Customized Approach sample templates have been removed, and it notes that these templates are available on the PCI SSC website.
3. Adding or clarifying applicability notes
PCI DSS v4.0.1 contains updated and clarified guidance for several requirements, particularly around applicability notes:
- Requirement 3: Protect Stored Account Data: Clarifies that requirements 3.3.1 and 3.3.2 do not apply to issuers and companies supporting issuing services with a legitimate and documented business need to store SAD (Sensitive Authentication Data).
- Requirement 6: Develop and Maintain Secure Systems and Software: Reverts to PCI DSS v3.2.1 language that patches/updates for critical vulnerabilities must be installed within 30 days, not for high-risk ones.
- Requirement 8: Identify Users and Authenticate Access to System Components: Adds an exception for user accounts authenticated with phishing-resistant authentication factors.
- Requirement 12: Support Information Security with Organizational Policies and Programs: Clarifies TPSP (Third Party Service Provider) requirements for supporting customer requests for information about PCI DSS compliance status and responsibilities.
Practical concerns for CEOs
As a CEO, ensuring your organization complies with PCI DSS v4.0.1 is crucial for maintaining customer trust, protecting sensitive data, and avoiding costly breaches or fines.
Here are some key practical concerns and steps to consider:
1. Ensuring smooth transition and compliance
Understand the changes: Familiarize yourself with the Summary of Changes from PCI DSS v4.0 to v4.0.1 available in the PCI SSC Document Library for an in-depth comparison. This will help you understand what is required and avoid compliance pitfalls.
Engage your team: Ensure that your compliance and IT teams are aware of the updates and understand their implications. Regular training and updates can help keep everyone aligned.
Resource allocation: Allocate sufficient resources, both in terms of budget and personnel, to address compliance requirements. Compliance can be resource-intensive, but the investment is crucial for long-term security and trust.
2. Risk management and data protection
Mitigate risks: Ensure that your organization has robust risk management strategies in place to identify, assess, and mitigate risks associated with cardholder data. Regularly update these strategies to reflect the latest standards.
Protect data: Implement strong data protection measures to safeguard cardholder data and sensitive authentication data. This includes encryption, secure storage, and regular audits to ensure compliance with PCI DSS requirements.
3. Operational efficiency
Leverage technology: Use advanced technology solutions to streamline compliance processes. Automated tools can help manage compliance tasks, monitor systems, and generate reports, reducing the burden on your team.
Monitor compliance continuously: Continuous monitoring and regular assessments are essential to maintain compliance. Ensure that your organization has the tools and processes in place for ongoing compliance management.
