Why Choose Accorp for Your PCI DSS Audit & Compliance Needs
We don’t just help you pass your audit — we ensure continuous, sustainable compliance with guidance from certified experts offering industry-leading PCI QSA services and PCI DSS audit services.
Scope & Environment Definition
Map and define your Cardholder Data Environment (CDE), including all systems, processes, and third-party interactions in scope — a critical part of meeting PCI DSS compliance levels and simplifying future assessments.
Gap Analysis & Risk Assessment
Perform a detailed gap analysis against PCI DSS reporting levels and other PCI requirements, identify weaknesses, and provide a prioritised remediation plan.
Policy, Procedure & Documentation Review
Audit existing policies, controls, and evidence (logs, diagrams, access controls), updating documentation to align with PCI standards such as PCI SSF requirements and wireless PCI compliance requirements.
Remediation Support & Control Implementation
Guide the fixing of vulnerabilities—implement missing controls, encryption, improved access management, and network segmentation, validating effectiveness to ensure an audit-ready environment.
Formal Assessment & Certification
Certified QSAs perform formal audits (RoC or SAQ), including support for PCI Level 2 compliance and SAQ A level PCI compliance, and issue Reports on Compliance (RoC) and Attestations of Compliance (AoC).
Ongoing Maintenance & Monitoring
Maintain compliance year-round via vulnerability scans and change management — leveraging automated PCI compliance and PCI compliance website checker options.
Our PCI DSS Compliance Process – Simple & Transparent
Our proven methodology ensures successful PCI DSS certification and ongoing compliance
Scoping & Environment Mapping
Identify all systems, processes, and third-party connections handling cardholder data — a key step in aligning with PCI DSS API security and network compliance. Define the Cardholder Data Environment (CDE) to focus audit efforts and minimise PCI compliance audit cost.
Gap Analysis & Risk Assessment
Compare current security controls against PCI DSS, SSF, P2PE, PIN, and 3DS requirements. Highlight vulnerabilities and provide a prioritised remediation plan that includes updates to PCI DSS compliance rules.
Remediation & Control Implementation
Implement missing controls, encryption, access management, and network segmentation. Validate effectiveness to ensure the CDE is audit-ready — including PCI validated P2PE and PCI P2PE SAQ options.
Formal Assessment & Certification
Certified QSAs perform SAQ or a full RoC audit. Issue Report on Compliance (RoC) and Attestation of Compliance (AoC), aligned with all relevant PCI DSS levels.
Ongoing Monitoring & Maintenance
Conduct periodic vulnerability scans, change management, and scope re-evaluation. Ensure continuous compliance, with additional support from ASV PCI compliance tools, PCI ASV pricing guidance, and top PCI ASV vendors with options like a free ASV scan.
Trusted by Industry Leaders
Global security standard for protecting cardholder data in payment environments. Covers network security, encryption, access controls, monitoring, and secure processing. Mandatory for merchants, processors, fintechs, and any entity handling card payments.
Types of PCI DSS Compliance
Comprehensive security and compliance solutions for your business
PCI SSF (Secure Software Framework)
Applies to organisations developing or maintaining payment software to ensure security throughout the software lifecycle.
PCI DSS Validation
Applies to merchants or service providers processing, storing, or transmitting cardholder data using multiple PCI QSA services.
PCI P2PE (Point-to-Point Encryption)
Encrypts cardholder data at the point of interaction (POI) to reduce PCI DSS scope and increase security.
PCI PIN Assessment
Secures PIN data during online and offline transactions as part of a detailed PCI compliance audit.
PCI 3DS (3-D Secure)
Provides authentication for card-not-present (CNP) online transactions to reduce fraud — also part of PCI 3DS compliance.

PCI DSS v4.0 Audits: Requirements, Merchant Levels & SAQ Qualification
The Payment Card Industry Data Security Standard (PCI DSS) is mandatory for any business that processes, stores, or transmits payment card data. Under PCI DSS v4.0, organizations must meet strict compliance controls to protect their Cardholder Data Environment (CDE) from evolving threats.
PA-DSS & PCI SSF Compliance (Software Security)
Software VendorsFor software developers, the retired Payment Application Data Security Standard (PA-DSS) has been replaced by the **PCI Software Security Framework (SSF)**. If you build payment applications that are sold, distributed, or licensed to third parties, you must certify under the Secure Software Standard (S3) and Secure Software Lifecycle (Secure SLC) standard. This ensures that your payment applications prevent unauthorised storage of sensitive authentication data (SAD) and are inherently secure against common code vulnerabilities.
Point-to-Point Encryption (P2PE) Validation
Scope ReductionImplementing a **PCI-validated Point-to-Point Encryption (P2PE) solution** is one of the most effective methods to reduce your Cardholder Data Environment (CDE) scope. A validated P2PE solution encrypts cardholder data immediately upon capture at the Point of Interaction (POI) terminal and keeps it encrypted until it reaches the secure decryption environment. By using a validated P2PE solution, merchants can drastically simplify their annual compliance verification, qualifying for the shortened **SAQ P2PE** self-assessment.
PCI DSS v4.0 vs v3.2.1 (Key Differences)
PCI DSS v4.0 introduces significant structural shifts, moving away from rigid checklist requirements toward a risk-focused framework.
Customized Control Design
Instead of following strictly defined controls, organizations can design custom controls to meet the explicit security objective of each requirement, backed by a formal QSA-reviewed targeted risk analysis.
Multi-Factor Authentication (MFA)
MFA is now mandatory for **all access** into the cardholder data environment (CDE), not just for remote administrative logins. Passwords must also be increased to a minimum length of 12 characters.
PCI DSS Merchant Compliance Levels
Compliance requirements scale based on your transaction volume. Level 1 merchants must undergo an annual on-site audit.
| Level | Annual Transactions | Audit Requirement |
|---|---|---|
| Level 1 | Over 6 million credit or debit card transactions | Annual QSA-led Report on Compliance (ROC) + Quarterly ASV Scan |
| Level 2 | 1 million to 6 million transactions | Self-Assessment Questionnaire (SAQ) + Quarterly ASV Scan |
| Level 3 | 20,000 to 1 million e-commerce transactions | Self-Assessment Questionnaire (SAQ) + Quarterly ASV Scan |
| Level 4 | Fewer than 20,000 e-commerce transactions | Self-Assessment Questionnaire (SAQ) + Quarterly ASV Scan |
Scope Reduction & Tokenization Strategies
Minimizing the footprint of cardholder data reduces audit timelines, risks of breach, and ongoing compliance costs.
Tokenization
Replace primary account numbers (PAN) with non-sensitive reference tokens. Cardholder data is stored exclusively in a secure third-party vault, removing your servers from CDE scope.
Hosted Payment Fields
Use iframe or hosted fields from payment processors (e.g., Stripe Elements, Adyen). This prevents card numbers from passing through your application servers, qualifying you for SAQ A.
Network Segmentation
Isolate your CDE from other corporate networks using strict firewall rules. Systems outside the segmented environment are not subject to audit requirements, shortening scope.
