Every organization that accepts card payments has to protect cardholder data and meet the requirements of the Payment Card Industry Security Standards Council (PCI SSC). The time, cost, and effort involved for compliance, however, can vary widely depending on how the payment environment is set up.
To save time and money, organizations should aim not only to meet these requirements, but also to keep as much of their payment environment out of scope as possible.
Key Takeaways
- PCI scope reduction limits the systems, processes, technologies, and people that must meet PCI DSS requirements by shrinking the cardholder data environment (CDE).
- Organizations can reduce PCI scope by limiting where cardholder data travels and using payment security technologies or third-party providers to keep it out of unnecessary parts of the business.
- A smaller PCI scope can lower compliance costs, reduce security risk, and make payment environments easier to manage and scale.
- Bluefin helps reduce PCI scope with PCI-validated P2PE, vaultless tokenization, and a processor-independent architecture designed to keep raw cardholder data out of more business systems.
What Is PCI Scope Reduction?
PCI scope reduction means limiting the systems, processes, technologies, and people that are subject to the Payment Card Industry Data Security Standard (PCI DSS), the industry security standard for protecting payment card data. The goal is to keep the cardholder data environment (CDE) as small as possible to make compliance easier to achieve.
Why is PCI Scope Reduction Important?
Reducing PCI scope can lower security risk and significantly reduce the time and resources required for payment security compliance.
Payment Environments Are Becoming More Complex
Payments today often travel across a wide range of systems, including websites, apps, terminals, cloud platforms, and third-party tools. Organizations also tend to work with more payment providers: 62% of merchants surveyed in 2025 said they preferred a multiprocessor setup, according to a 451 Research Pathfinder Paper. These trends are making CDEs both larger and more complicated.
Compliance Requirements Require Extensive Resources
With a larger CDE comes a larger PCI scope, requiring more resources to manage and document the environment in order to stay compliant.
PCI Scope Impacts Teams Beyond Compliance
A larger CDE – including more systems along with their corresponding access controls and security measures – can also create more work for IT and security teams due to the additional integrations and operational complexities involved.
Data Exposure Is a Business Risk
When systems that don’t need cardholder data still store, process, or transmit it, they add unnecessary cybersecurity risks that can cause financial and reputational damage.
5 Ways to Reduce PCI Scope
Reducing PCI scope generally means keeping cardholder data out of systems that don’t need it. To shrink the CDE, organizations can:
1. Minimize Cardholder Data
Limit where cardholder data is stored, processed, or transmitted so that fewer systems are a part of the CDE.
2. Segment the Cardholder Data Environment
Isolate the CDE from systems that do not need access to cardholder data to limit unnecessary PCI scope.
3. Use Tokenization
Replace cardholder data with tokens – non-sensitive substitutes for the original data – through tokenization. This allows business systems to continue many functions using tokens instead of raw card data.
4. Adopt PCI-Validated P2PE
Protect card data as it travels through the payment environment with PCI-validated point-to-point encryption (P2PE), which encrypts cardholder data at the point of interaction and keeps it unreadable until it reaches the secure decryption environment. P2PE that is PCI-validated can reduce assessment requirements by up to 90% in card-present environments because the solution has already been assessed by the PCI SSC.
5. Outsource Payment Processing
Use third-party payment providers that process cardholder data through outside systems to reduce the amount of the payment environment that must be managed directly.
What Are the Business Benefits of Reducing PCI Scope?
A smaller PCI scope can save businesses time and money while lowering security risk.
Simplify PCI DSS Compliance
With fewer systems in scope, compliance becomes easier because organizations have less to document, monitor, and assess.
Reduce Compliance Costs
A smaller CDE can reduce spending on audits, remediation, and other compliance-related work.
Lower Payment Security Risks
Shrinking the CDE can reduce the attack surface and the number of systems where payment data could be exposed.
Improve Operational Efficiency
Security, IT, and compliance teams can spend less time conducting safety and compliance-related activities.
Scale Payment Infrastructure
Reducing PCI scope can make it easier to modernize applications and integrate new technologies or payment experiences without expanding the CDE.
How to Make PCI Scope Reduction an Ongoing Priority
PCI DSS requires organizations to confirm their scope at least once every 12 months and after significant changes to the in-scope environment. But PCI scope is better managed continuously, because payment environments can change throughout the year as organizations change and grow.
Regularly map where cardholder data is stored, processed, and transmitted to see when new systems enter the CDE. Whenever new technologies or payment options are introduced, consider how they could affect PCI scope before they are implemented.
Reduce PCI Scope with Bluefin
Bluefin combines PCI-validated P2PE and tokenization to keep raw cardholder data out of more business systems without requiring organizations to replace their existing payment infrastructure.
With Bluefin’s P2PE-as-a-Service, cardholder data can be encrypted from the point of interaction without organizations having to build and manage their own P2PE program. Bluefin ShieldConex® can also replace sensitive card data with tokens for systems that still need to use payment information for functions such as recurring payments or refunds.
Together, these technologies can limit where usable cardholder data travels and reduce the systems and processes that need to be included in PCI scope. Bluefin’s processor-independent architecture also allows organizations to apply these protections across different payment processors.
PCI Scope Reduction FAQs
Can PCI DSS scope be completely eliminated?
Yes, if an organization doesn’t accept card payments or otherwise store, process, or transmit cardholder data. Organizations that accept card payments can reduce their PCI scope, but generally can’t entirely eliminate PCI DSS responsibilities.
Can a system be in PCI DSS scope even if it does not store cardholder data?
Yes. Systems that process or transmit cardholder data – or connect to or could affect the security of the cardholder data environment – can also be in scope.
Does reducing PCI scope change PCI DSS compliance requirements?
No. Reducing PCI scope doesn’t change the PCI DSS requirements themselves. Instead, it reduces the number of systems, processes, technologies, and people that need to meet those requirements.
What documentation is needed to demonstrate that a system is out of PCI DSS scope?
Documentation should show where cardholder data flows and how systems are separated from the CDE. Any controls used to keep systems out of scope should also be documented.
How does PCI-validated P2PE help reduce PCI scope?
PCI-validated P2PE encrypts cardholder data as soon as it is entered to keep readable card data out of surrounding systems and networks. This can reduce PCI scope in point-of-sale environments by up to 90%.
How often should organizations review their PCI scope?
PCI DSS requires organizations to confirm their scope at least once every 12 months and after significant changes to the in-scope environment, but organizations can benefit from managing scope continuously as technologies and workflows change.
