01
Reduce Unnecessary Scope
Identify where account data really flows, remove unnecessary storage and isolate the systems that genuinely need to be inside the cardholder data environment.
PCI DSS Compliance Services
Make PCI DSS Compliance Clearer, Smaller and Easier to Maintain
PCI DSS compliance should protect payment data without consuming the business. 2-sec helps merchants and service providers define the right scope, close the right gaps and prepare confidently for PCI DSS v4.0.1 validation.
Our Qualified Security Assessors work with your teams from scoping and gap analysis through remediation, evidence preparation, SAQ or Report on Compliance assessment, and ongoing compliance support.
02
Know What Must Change
Translate PCI DSS requirements into a prioritised remediation plan across technology, people, policies, third parties and operating processes.
03
Maintain Compliance
Move beyond a point-in-time audit with practical support for recurring evidence, testing, risk analysis and time-sensitive controls throughout the year.
Payment Security Without the Guesswork
What Is PCI DSS Compliance
PCI DSS is the global payment card data security standard for organisations that store, process or transmit account data, or whose systems could affect the security of the cardholder data environment. It defines technical and operational controls designed to protect payment data throughout its lifecycle.
For most organisations, the hardest part is not reading the standard. It is understanding how PCI DSS applies to the way payments actually move through the business.
That makes scoping the starting point. 2-sec maps payment flows, connected systems, people, locations and third-party service providers, then helps reduce the cardholder data environment wherever there is a defensible way to do so. A smaller, clearer scope usually means less complexity, less evidence to maintain and a more efficient compliance programme.

The Real Work Behind PCI
Compliance Reaches Beyond the Firewall
PCI DSS is a security standard, but successful compliance depends on coordinated controls across technology, operating processes, people and suppliers.
Discuss Your PCI Scope ↗Network SecuritySegmentation, security controls, secure configurations and the boundaries of the CDE.
Account Data ProtectionStorage, retention, encryption, transmission and removal of data that does not need to be retained.
Vulnerability ManagementPatching, malware protection, secure development, vulnerability scanning and penetration testing.
Access ControlLeast privilege, identity, authentication, user lifecycle controls and physical access.
Monitoring and TestingLogging, alerting, change detection, security testing and evidence that controls are operating.
Policies and GovernanceRoles, responsibilities, risk processes, incident response, security awareness and programme ownership.

Our PCI DSS Approach
A Clear Route From Uncertainty to Validation
The exact route depends on your environment and validation obligations, but most engagements follow the same practical sequence.
01
Scope
Understand payment channels and data flows, identify systems and third parties that can affect the CDE, confirm validation obligations and establish a defensible scope.
02
Assess
Review applicable PCI DSS v4.0.1 requirements, interview stakeholders, inspect policies and systems, and identify areas of non-compliance or weak evidence.
03
Prioritise
Turn findings into a practical remediation roadmap, distinguishing urgent security exposures from documentation, process and longer-term architectural changes.
04
Remediate
Work with your teams to resolve gaps, strengthen controls, reduce unnecessary account-data exposure and prepare evidence for validation.
05
Validate
Complete the appropriate SAQ or QSA-led Report on Compliance assessment, verify that controls operate as intended and resolve any final assessment items.
06
Maintain
Keep the programme current through recurring control activities, security testing, risk analyses, third-party oversight and evidence maintenance throughout the year.

PCI DSS Questions
Frequently Asked Questions
What is the current version of PCI DSS?
PCI DSS v4.0.1 is the active version of the standard. PCI DSS v4.0 was retired at the end of 2024, and the future-dated v4.x requirements became effective after 31 March 2025.
Does PCI DSS apply if we outsource payment processing?
Potentially, yes. Outsourcing can significantly reduce scope, but it does not automatically remove every PCI DSS responsibility. Your responsibilities depend on how payments are handled, what systems can affect the payment process, which third parties are used and the validation route that applies.
What is a Cardholder Data Environment?
The Cardholder Data Environment, or CDE, includes people, processes and technologies that store, process or transmit account data, plus system components that can affect the security of that environment. Defining this boundary correctly is central to PCI DSS scoping.
Do we need a QSA?
That depends on your validation obligations and the requirements set by your acquiring bank, card brands, customers or other compliance programme stakeholders. Some organisations can validate through an SAQ, while others require a QSA-led Report on Compliance.
What is a PCI DSS gap analysis?
A gap analysis compares your current controls and evidence with the PCI DSS requirements that apply to your environment. It identifies weaknesses early so they can be remediated before a formal assessment or validation deadline.
What is the difference between an SAQ and a Report on Compliance?
A Self-Assessment Questionnaire is a PCI SSC validation tool used by eligible merchants and service providers. A Report on Compliance is a more extensive assessment record typically completed where formal QSA validation is required. The correct route depends on eligibility and the requirements of the entity to which you report compliance.
Can segmentation reduce PCI DSS scope?
Yes, effective segmentation can isolate the CDE from systems that do not need to be in scope. The segmentation must be properly designed, implemented and, where applicable, tested so the reduced scope is defensible.
Is PCI DSS a once-a-year project?
No. Many PCI DSS controls operate continuously or on recurring schedules. Vulnerability scanning, penetration testing, log review, risk analysis, access management, third-party oversight and other activities need to remain operational between formal validations.
Can 2-sec help us reduce our PCI DSS scope?
Yes. Scope reduction is one of the most valuable parts of a PCI engagement. 2-sec can review payment flows and architecture, identify unnecessary account-data handling and advise on segmentation, outsourcing or process changes that may reduce the size and complexity of the environment.
Can 2-sec help with remediation after a failed or difficult assessment?
Yes. 2-sec can review findings, prioritise remediation and work with internal teams to address technical, process, policy and evidence gaps before retesting or revalidation.
