PCI-DSS Compliance
Payment card industry data security standard compliance assessments and certification support.
The Payment Card Industry Data Security Standard (PCI-DSS) is a comprehensive set of security requirements established by the PCI Security Standards Council to protect cardholder data and reduce payment card fraud. Governed by American Express, Discover, JCB, Mastercard, and Visa, PCI-DSS applies to any organization that stores, processes, or transmits cardholder data, including merchants, payment processors, acquirers, issuers, and service providers. The standard is organized into six control objectives encompassing twelve requirements that cover network security, cardholder data protection, vulnerability management, access control, network monitoring, and information security policy. Compliance is not optional — it is mandated by the payment card brands through contractual agreements, and non-compliance can result in significant fines, increased transaction fees, and the loss of card acceptance privileges.
The twelve PCI-DSS requirements provide a comprehensive framework for cardholder data security. Requirement 1 mandates installing and maintaining firewall and network segmentation configurations to protect cardholder data environments. Requirement 2 prohibits vendor-supplied defaults for system passwords and other security parameters. Requirement 3 requires protecting stored cardholder data through encryption, truncation, masking, and hashing, with strict limitations on data retention and storage. Requirement 4 requires encrypting transmission of cardholder data across open, public networks. Requirement 5 mandates using and regularly updating anti-malware software. Requirement 6 requires developing and maintaining secure systems and applications. Requirement 7 mandates restricting access to cardholder data by business need-to-know. Requirement 8 requires assigning unique IDs to each person with computer access. Requirement 9 mandates restricting physical access to cardholder data. Requirement 10 requires tracking and monitoring all access to network resources and cardholder data. Requirement 11 mandates regularly testing security systems and processes. Requirement 12 requires maintaining a policy that addresses information security for all personnel.
PCI-DSS compliance validation varies based on an organization's merchant level, which is determined by transaction volume. Level 1 merchants (over 6 million Visa transactions annually) must undergo an annual on-site assessment by a Qualified Security Assessor (QSA) and quarterly network scans by an Approved Scanning Vendor (ASV). Level 2 (1-6 million transactions), Level 3 (20,000-1 million e-commerce transactions), and Level 4 (less than 20,000 e-commerce transactions) merchants may validate compliance through Self-Assessment Questionnaires (SAQs) with varying complexity, along with quarterly ASV network scans. There are nine SAQ types tailored to different payment environments, ranging from SAQ A for merchants who fully outsource cardholder data processing to SAQ D for the most complex environments. Service providers, regardless of volume, must undergo annual QSA assessments and maintain compliance programs. The specific validation requirements depend on your acquirer's requirements and your organization's specific payment processing environment.
Our PCI-DSS compliance practice combines deep technical expertise with extensive experience across all merchant levels, SAQ types, and payment environments. We begin with a comprehensive scoping exercise to precisely define your cardholder data environment (CDE), identifying every system, network segment, application, and process that stores, processes, or transmits cardholder data or sensitive authentication data. Our QSAs and PCI experts then conduct a thorough gap assessment against all applicable PCI-DSS requirements, producing a detailed remediation roadmap with prioritized findings. We provide hands-on support throughout the remediation process, including network segmentation design, firewall configuration review, encryption implementation guidance, access control deployment, logging and monitoring setup, security testing coordination, and policy and procedure development. We coordinate all ASV scanning activities, manage the SAQ or Report on Compliance (ROC) process, and provide full QSA liaison support during your formal assessment. Our approach ensures that compliance is achieved efficiently and maintained continuously through automated monitoring and periodic reassessment.
How We Deliver
A structured methodology refined through hundreds of successful engagements.
CDE Scoping & Discovery
We begin by conducting a thorough discovery exercise to define the precise boundaries of your cardholder data environment. Our assessors identify every system, network device, application, database, server, virtual machine, container, and third-party service that stores, processes, or transmits cardholder data or sensitive authentication data. We map data flows from the point of card entry through authorization, settlement, tokenization, storage, and disposal. This scoping exercise also identifies connected systems and networks that could impact CDE security, allowing us to develop a network segmentation strategy that minimizes the scope of PCI-DSS compliance. Precise scoping is the most critical phase of the engagement, as scope reduction through effective segmentation directly reduces compliance cost, complexity, and risk.
Gap Assessment & Risk Analysis
With the CDE scope defined, we conduct a comprehensive gap assessment against all twelve PCI-DSS requirements and their associated sub-requirements. Our assessors examine network architecture diagrams, firewall rule sets, system configurations, application code, encryption implementations, access control mechanisms, logging and monitoring systems, security testing results, and information security policies. Each requirement is evaluated and rated for compliance status with detailed findings, evidence of compliance, or documentation of gaps. The resulting gap assessment report provides a prioritized inventory of findings organized by severity, with specific remediation recommendations, effort estimates, and responsible parties. We also conduct a risk analysis for each identified gap to help organizations prioritize remediation efforts based on actual risk exposure.
Remediation & Control Implementation
Working from the gap assessment findings, our team provides hands-on remediation support across all PCI-DSS requirements. We help redesign network architectures to achieve effective segmentation, review and optimize firewall rule sets, implement encryption solutions for data at rest and in transit, deploy and configure access control systems with unique user identification and role-based access, implement logging and monitoring solutions with centralized log management and security information and event management integration, configure file integrity monitoring, and develop comprehensive information security policies and procedures. Throughout remediation, we conduct iterative validation testing to confirm that implemented controls satisfy PCI-DSS requirements. Our engineers work directly with your IT, security, and development teams to ensure that remediation is technically sound and operationally sustainable.
Security Testing & ASV Scanning
We coordinate and manage all security testing required for PCI-DSS compliance validation. This includes quarterly external and internal network vulnerability scans conducted by Approved Scanning Vendors (ASVs), as well as internal vulnerability scans that must be performed on a quarterly basis and after any significant network changes. We also manage the penetration testing required by Requirement 11.3, including network layer penetration tests and application layer penetration tests covering the CDE and critical systems, performed at least annually and after any significant infrastructure or application changes. Our team reviews all scan and test results, coordinates remediation of any identified vulnerabilities, manages rescanning processes, and maintains comprehensive documentation of testing activities, findings, and remediation evidence for QSA review and audit records.
Assessment, Validation & Certification
We prepare and submit the appropriate compliance validation documentation based on your merchant level and processing environment. For self-assessed merchants, we complete the appropriate SAQ with supporting evidence attachments and executive sign-off. For Level 1 merchants and service providers requiring on-site assessments, our QSAs prepare the Report on Compliance (ROC) and Attestation of Compliance (AOC), coordinate with your acquiring bank and the payment card brands, and manage the entire assessment lifecycle. We provide continuous support during the QSA assessment, including evidence gathering, staff interviews, facility walkthroughs, and system demonstrations. Following successful validation, we establish an ongoing compliance maintenance program including periodic control reviews, policy updates, quarterly scan scheduling, and preparation for the next annual assessment cycle.
