The latest version of PCI DSS standards represents the most significant overhaul of payment security requirements in years. For businesses that handle credit card data, staying current with these changes isn’t just good practice—it’s essential for maintaining compliance and protecting customer information.
PCI DSS (Payment Card Industry Data Security Standard) was first established in 2004 to create a unified approach to safeguarding payment card information. The standard has evolved considerably since then, with version 4.0 marking only the third major revision in nearly two decades.
As Derek Brink, Vice President and Research Fellow at Aberdeen Group, noted:
“Over the course of several years now, the PCI Security Standards Council has done a laudable job at defining and evolving a cohesive set of standards, as well as at listening and adapting over time to the feedback from merchants, banks, payment processors, service providers, and technology providers.”
This latest update increases the total number of requirements from 370 to over 500, introducing 64 new requirements while maintaining the framework of 12 core principles. Many of these changes respond directly to emerging threats like phishing, e-skimming, and sophisticated web-based attacks.
For businesses handling payment card data, understanding these changes is crucial—especially with the March 31, 2024 compliance deadline now passed and future-dated requirements approaching in 2025.

The Latest Version of PCI DSS Standards: v4.0.1 Explained
The journey to the latest version of PCI DSS standards reflects a thoughtful evolution rather than a revolution. Version 4.0 arrived on March 31, 2022, following an impressive three-year development process. This wasn’t just the PCI Council working in isolation – they gathered input from over 200 organizations worldwide and addressed more than 6,000 pieces of feedback. That’s what I call listening to your stakeholders!
More recently, in June 2024, the Council released version 4.0.1 – a minor but helpful update that corrects errors and clarifies guidance from the original v4.0 document. Think of it as a touch-up rather than a makeover – v4.0.1 doesn’t add new requirements but makes the existing ones easier to understand and implement.
At its heart, PCI DSS still revolves around 12 core requirements, neatly organized into six control objectives. These fundamentals haven’t changed, but how we approach them certainly has:
- Build and Maintain a Secure Network and Systems covers installing network security controls and applying secure configurations.
- Protect Account Data focuses on safeguarding stored account data and using strong cryptography during transmission.
- Maintain a Vulnerability Management Program addresses protection from malicious software and developing secure systems.
- Implement Strong Access Control Measures ensures access restrictions, proper user identification, and physical security.
- Regularly Monitor and Test Networks emphasizes logging, monitoring, and regular security testing.
- Maintain an Information Security Policy supports security through organizational policies and programs.
What’s particularly noteworthy is how the latest version of PCI DSS standards has expanded these requirements. We’ve gone from 370 test steps in v3.2.1 to over 500 in v4.0/4.0.1, including 64 brand-new controls. That’s a substantial increase that reflects the growing complexity of payment security challenges.
| Aspect | PCI DSS v3.2.1 | PCI DSS v4.0/4.0.1 |
|---|---|---|
| Total Requirements | 370 | 500+ |
| New Requirements | N/A | 64 |
| Password Length | 8 characters | 12 characters |
| MFA Requirements | Limited scope | Expanded to all access to CDE |
| Customized Approach | Compensating controls | Formalized customized approach |
| Authentication | Password-focused | Multi-layered, risk-based |
| Emerging Threats | Limited coverage | Improved phishing, e-skimming protection |
| Service Provider Requirements | Basic | Expanded (especially for Requirement 12) |
| Documentation | General | Detailed scope documentation required |
What changed from v3.2.1 to the latest version of PCI DSS standards?
The changes in the latest version of PCI DSS standards aren’t random – they follow clear patterns that help us understand the Council’s priorities.
First, we have evolving requirements – these are completely new additions addressing emerging threats or technologies. All 64 new requirements fall here, reflecting how payment security must adapt to a changing landscape.
Then there are clarification or guidance updates. These don’t change what you need to do security-wise but make it clearer how to do it. Think of these as better directions for the same destination.
Finally, structure or format changes reorganize content for better readability without altering the security objectives. Better organization means easier implementation – a win for everyone.
It’s telling that 22% of the new requirements apply to Requirement 12 (information security policies and programs). This highlights a shift toward formal documentation, risk analysis, and organizational accountability. The Council clearly believes that good security starts with good governance.
Perhaps the most practical change for many organizations is the introduction of 51 “future-dated” requirements. While technically part of the standard now, you have until March 31, 2025, to implement these. Until then, they’re best practices rather than mandatory controls – giving you breathing room to adapt.
The latest version of PCI DSS standards also accepts a more risk-based philosophy. Rather than prescribing identical solutions for every business, v4.0 encourages you to assess your specific risks and implement appropriate controls. This approach is formalized through the new customized implementation option and requirements for targeted risk analyses.
At Concertium, we’ve noticed this shift aligns perfectly with how modern security programs should operate – recognizing that context matters and that effective security must be custom to your unique environment.
Core Objectives, Major Security Improvements & Service Provider Impact
The latest version of PCI DSS standards isn’t just a routine update—it’s a thoughtful evolution designed to meet today’s complex security challenges. At its heart, the standard aims to accomplish four essential goals: ensuring it meets the payment industry’s evolving security needs, adding flexibility through alternative security approaches, promoting security as an ongoing process (not a one-time checkbox), and improving how organizations validate their compliance.
One of the most exciting changes in version 4.0 is the introduction of the customized approach. Unlike the old compensating controls system (which felt more like an exception process), this new approach gives organizations breathing room to design security controls that actually fit their unique environments.
Think of it as moving from a one-size-fits-all approach to a custom security suit. To make this work, you’ll need to document how your custom control meets the security objective, analyze the specific risks, show that your approach is appropriate, and provide evidence that it’s working effectively. This flexibility is particularly valuable if you have a complex environment or use technologies that weren’t around when the standard was written.
Beyond this customized approach, the latest version of PCI DSS standards brings several meaningful security improvements:
Role-Based Policies now require clearly defined responsibilities for security functions, ensuring everyone knows exactly who’s accountable for what. No more “I thought someone else was handling that” situations.
Password Requirements have gotten stronger, with minimum lengths increasing from 8 to 12 characters. This simple change dramatically increases password security against brute force attacks.
Multi-Factor Authentication (MFA) is now required everywhere in your cardholder data environment—not just for remote access. This reflects the reality that internal threats are just as concerning as external ones.
Phishing Defense gets serious attention with new requirements for awareness training and technical controls, acknowledging that human vulnerability remains one of the biggest security gaps.
E-commerce Protection now mandates web application firewalls to detect and prevent web-based attacks like e-skimming, which has become increasingly common on payment pages.
For service providers, Requirement 12.9.2 introduces a significant new obligation: you must now be prepared to show your customers documentation about your PCI DSS compliance status and which specific requirements you’re handling for them. This transparency requirement recognizes that many organizations rely on third parties for critical payment functions.
The standard also places much greater emphasis on continuous monitoring and risk analysis. Organizations must now formally assess risks in several key areas including password policies, cryptographic key management, network segmentation, and e-commerce security.
At Concertium, our PCI Compliance Risk Assessment services help organizations steer these new requirements with structured approaches to identifying, analyzing, and documenting payment security risks—taking the guesswork out of compliance.
How the latest version of PCI DSS standards tackles emerging threats
The latest version of PCI DSS standards doesn’t just address yesterday’s threats—it looks ahead to the evolving tactics used by today’s cybercriminals.
Remember when phishing was just a curious term? Now it’s one of the most common attack vectors, which is why Requirements 5.4.1 and 12.6.3.1 mandate anti-phishing training for staff and formal security awareness programs. The standard recognizes that even the best technical controls can be circumvented by a single employee clicking the wrong link.
Browser-based attacks have become increasingly sophisticated, with attackers injecting malicious code directly into payment pages. Requirement 6.4.2 addresses this by requiring automated solutions like Web Application Firewalls to detect and prevent these attacks before they can skim card data.
Physical security gets an upgrade too, with Requirements 9.5.1.2.1 and 11.6.1 introducing new controls for detecting physical tampering of payment devices. These requirements help spot suspicious activity that might indicate someone has physically modified a payment terminal—something that’s become increasingly common at gas stations and retail locations.
Software development practices receive much-needed attention through Requirements 6.2.4 and 6.3.2, which improve controls around secure coding. Developers must now be trained in secure coding techniques, acknowledging that security must be built in from the start, not added as an afterthought.
Many requirements previously found in the Designated Entities Supplemental Validation (DESV) document have now been incorporated into the main standard, raising the security bar for everyone. This reflects the reality that threats once faced only by the largest organizations are now common across the board.
Service provider-specific changes
If you’re a service provider handling payment data, the latest version of PCI DSS standards places additional responsibilities on your shoulders.
Supporting Evidence requirements have increased significantly. Requirement 12.9.2 means you’ll need to clearly document which PCI DSS requirements you cover and which remain your customers’ responsibility. This helps eliminate those awkward “I thought you were handling that” conversations during audits.
Testing Frequency has increased for service providers. While merchants can perform internal penetration testing annually, service providers must now do this at least every six months (Requirement 11.3.1.1). You’ll also need targeted detection mechanisms to alert your team to suspicious activities around critical files and systems (Requirement 11.6.1).
Customer Attestations have become more formal under Requirements 12.8.4 and 12.8.5. You’ll need to maintain a program to monitor your own service providers’ PCI DSS compliance status and clearly document which requirements are managed by each provider in your supply chain.
Your Security Program needs to be more formalized as well. Requirement 12.10.5 mandates establishing a security awareness program specifically for personnel with security breach response responsibilities, ensuring your incident response team is properly prepared.
These service provider requirements highlight an important truth: payment security is a shared responsibility. Clear documentation of who handles what security controls is no longer optional—it’s essential for maintaining trust in our interconnected payment ecosystem.
Implementation Timeline, Future-Dated Controls & Prioritized Compliance
Navigating the transition to the latest version of PCI DSS standards feels a bit like planning a cross-country road trip – you need clear milestones, enough time to prepare, and a good understanding of what lies ahead. Fortunately, the PCI Council has mapped out a thoughtful journey for organizations.
The implementation roadmap unfolds across several key dates:
- March 31, 2022: PCI DSS v4.0 made its grand entrance
- March 31, 2024: PCI DSS v3.2.1 officially retired, with v4.0 becoming the only valid version
- June 2024: PCI DSS v4.0.1 arrived with helpful clarifications and corrections
- March 31, 2025: The 51 future-dated requirements become mandatory
That two-year transition window between 2022 and 2024 gave organizations breathing room to understand and adapt to the new requirements. During this period, businesses could validate against either v3.2.1 or v4.0 – a bit like having training wheels while learning to ride a new bike. But now that March 31, 2024 has passed, all assessments must use v4.0/v4.0.1 as the measuring stick.
Perhaps the most significant challenge ahead is tackling those 51 future-dated requirements. While they don’t become mandatory until March 31, 2025, smart organizations are already rolling up their sleeves. Some of these requirements represent substantial shifts in security practices, including:
- Formal acknowledgment of responsibilities by cryptographic key custodians
- Dedicated anti-phishing training for all personnel
- Improved management of payment page scripts
- Support for password managers
- Expanded multi-factor authentication throughout the cardholder data environment
- Improved protection techniques for critical systems
To help make this journey less overwhelming, the PCI Council developed the Prioritized Approach – a practical roadmap that organizes requirements into six risk-based milestones:
- Remove sensitive authentication data and limit data retention – the “low-hanging fruit” that immediately reduces risk
- Protect systems and networks and prepare for breach response – establishing your security foundation
- Secure payment card applications – hardening the software that processes payments
- Monitor and control access to your systems – knowing who’s doing what, when
- Protect stored cardholder data – safeguarding your most valuable information
- Finalize remaining compliance efforts – crossing the finish line with all controls in place
This prioritized approach isn’t just about checking boxes – it’s about focusing your limited resources on the controls that deliver the biggest security bang for your buck. It’s like deciding to fix your roof before repainting your fence – both matter, but one is clearly more urgent.
Another notable aspect of the latest version of PCI DSS standards is the increased emphasis on targeted risk analyses. These aren’t just paperwork exercises – they’re crucial tools for understanding your unique threat landscape and making informed security decisions. These analyses need to be documented and should guide your implementation strategy, especially if you’re using the customized approach.
At Concertium, we’ve helped countless organizations steer these waters through our Compliance and Risk Management services. We provide structured methodologies for conducting and documenting these targeted risk analyses, ensuring your security investments align with your actual risks – not just theoretical ones.
Compliance isn’t a one-time achievement but an ongoing journey. The latest version of PCI DSS standards recognizes this reality by encouraging a continuous, risk-based approach to payment security that evolves alongside emerging threats and changing business needs.
Transition Checklist, Documentation & Ongoing Validation Strategy
Moving to the latest version of PCI DSS standards doesn’t have to feel like climbing Mount Everest. While it’s certainly a journey, having a clear roadmap makes all the difference. Let’s walk through what this transition looks like for your organization.
Starting with a comprehensive gap analysis is your first step. Think of it as taking inventory of what you already have versus what you need. By comparing your current security controls against v4.0 requirements, you’ll quickly identify where your organization needs to improve. This isn’t just about checking boxes—it’s about understanding your risk exposure and prioritizing your efforts where they’ll have the greatest impact.
Documentation has taken center stage in PCI DSS 4.0, particularly with Requirement 12.5.2. This isn’t just paperwork for paperwork’s sake—it’s about truly understanding your environment. You’ll need to thoroughly document your PCI DSS scope annually and whenever significant changes occur.
“Documentation is like insurance,” says a seasoned QSA. “You hope you never need it, but when you do, you’re incredibly grateful it exists.”
Your scope documentation should paint a clear picture of how cardholder data flows through your organization. Think data flow diagrams, network maps, system inventories, and detailed descriptions of how you’ve separated your cardholder data environment from the rest of your systems.
Authentication requirements have received a significant upgrade in the latest version of PCI DSS standards. You’ll need to extend multi-factor authentication to all access points to your cardholder data environment—not just remote connections. Those 8-character passwords? They’re a thing of the past. The new minimum is 12 characters, and by March 2025, you’ll need to implement password management technology to make this manageable for your team.
Security testing has evolved from a point-in-time activity to an ongoing process. Continuous monitoring is the name of the game now. Your vulnerability management procedures need updating, your security controls require constant monitoring, and you’ll need regular penetration testing against your segmentation controls to ensure they’re truly effective.
Don’t overlook your policies and procedures. They need to address all PCI DSS requirements, clearly define roles and responsibilities, and incorporate formal change management processes. These documents aren’t just for show—they’re the foundation of your security program.
When it comes time for validation, you’ll need to determine whether your organization requires a Report on Compliance (ROC) or can use a Self-Assessment Questionnaire (SAQ). Either way, collecting and organizing evidence is crucial. Many organizations find working with a Qualified Security Assessor (QSA) invaluable during this process, even if not strictly required.
Ongoing validation isn’t a once-a-year scramble anymore. The latest version of PCI DSS standards pushes organizations toward continuous compliance monitoring. This includes:
- Using automated tools to constantly check security controls
- Regular vulnerability scanning and penetration testing
- Comprehensive logging with alerts for suspicious activity
- Periodic reviews of who has access to what
- Regular testing to ensure your team knows what to do
Automation has become essential for maintaining compliance without drowning your security team in manual tasks. At Concertium, our Compliance Automation Software helps organizations collect evidence, test controls, and maintain documentation automatically, freeing your team to focus on actual security work rather than paperwork.
The stakes for non-compliance are higher than ever. Beyond the financial penalties from payment card brands and increased transaction fees, you could face mandatory forensic investigations after breaches. The reputational damage alone can be devastating, and in extreme cases, you might lose your ability to process card payments altogether.
Our Cybersecurity Compliance Services provide the expertise and tools needed to maintain ongoing compliance with the latest version of PCI DSS standards, helping you protect sensitive data while meeting regulatory requirements.
FAQs about the latest version of PCI DSS standards
Do small merchants need to comply with all the new requirements in PCI DSS v4.0?
Yes, all merchants that accept payment cards must comply with PCI DSS, regardless of size. The good news? Validation requirements vary based on transaction volume. If you’re a small merchant, you’ll likely qualify for simplified validation using Self-Assessment Questionnaires (SAQs) that only cover requirements relevant to your specific payment setup. The PCI Council has updated all SAQs to align with v4.0, making compliance more accessible for smaller businesses.
Are future-dated controls optional until March 31, 2025?
Technically, yes—but don’t fall into the procrastination trap. While these requirements aren’t mandatory until March 2025, many involve significant changes to your technology, processes, and staff training. Starting now gives you breathing room to implement these changes thoughtfully rather than rushing as the deadline approaches. Think of it as preparing for a marathon, not a sprint.
How do customized approaches affect audits and assessments?
The customized approach offers flexibility, but it comes with homework. You’ll need to provide robust documentation during assessments, including detailed descriptions of security objectives, targeted risk analyses, documentation of implemented controls, and evidence that these controls work effectively. Your assessor will evaluate whether your customized controls provide at least the same protection level as the defined approach. It’s more work upfront, but can be worth it for organizations with unique environments.
Can we use compensating controls under PCI DSS v4.0?
Yes, compensating controls still exist in v4.0, but they’re now distinct from the customized approach. You’d use compensating controls when legitimate technical or business constraints prevent meeting a requirement exactly as written. The customized approach is broader, allowing alternative controls even without such constraints, provided they meet the security objective. Think of compensating controls as a workaround for specific obstacles, while the customized approach is a different path to the same destination.
How does the new requirement for targeted risk analyses work?
The latest version of PCI DSS standards requires documented risk analyses for several requirements. These aren’t just check-the-box exercises—they need to follow a formal methodology, happen at least annually (and after significant changes), address specific requirements, include relevant threats and vulnerabilities, and get senior management approval. These analyses guide your security control implementation and must be available for review during assessments. They’re essentially your justification for why you’ve implemented controls the way you have.
Does PCI DSS v4.0 require tokenization?
No, tokenization isn’t explicitly required by PCI DSS v4.0. However, it’s like a secret weapon for reducing PCI scope. By replacing cardholder data with tokens that have no exploitable value, you can significantly reduce the number of systems subject to PCI DSS requirements. For many organizations, tokenization is a strategic choice that simplifies compliance efforts while enhancing security.
Conclusion
The latest version of PCI DSS standards marks a genuine turning point in payment security. It’s not just another update—it’s a thoughtful evolution that balances flexibility with stronger security measures. Gone are the days of rigid compliance checklists; now organizations can customize their approach while still meeting core security objectives.
This shift reflects a growing understanding that security isn’t one-size-fits-all. Whether you’re a small retailer or a global payment processor, the new standards provide a framework that can adapt to your unique environment—while still ensuring cardholder data remains protected.
The journey to compliance doesn’t need to be overwhelming. Start by taking these practical steps:
Understand where you stand through a thorough gap analysis. This honest assessment will reveal the distance between your current security controls and where you need to be. Many organizations are surprised to find they’re already doing many things right!
Focus your efforts where they matter most by prioritizing based on risk and implementation deadlines. Not all requirements demand immediate attention—some can wait until you’ve addressed the most critical vulnerabilities.
Document everything carefully, especially your scope and controls. The new standards place greater emphasis on documentation, and for good reason: you can’t protect what you don’t understand.
Build continuous monitoring into your routine rather than treating compliance as an annual event. Regular testing and validation help catch security issues before they become serious problems.
Don’t wait until the last minute to address future-dated requirements. March 31, 2025, might seem far away, but implementing new authentication protocols and phishing controls takes time and careful planning.
