A PCI DSS assessment evaluates your organization’s compliance with standards set by the Payment Card Industry Security Standards Council. Depending on your card transaction volume, you’ll either complete a Self-Assessment Questionnaire (SAQ) or work with a Qualified Security Assessor (QSA) to conduct a formal PCI audit process.
PCI DSS compliance ensures secure handling of payment card data through rigorous audit procedures, risk mitigation, and implementation of validated security controls. A comprehensive PCI DSS risk assessment identifies vulnerabilities in your payment processing systems and establishes protocols to safeguard sensitive cardholder information.
Organizations that successfully complete their assessment receive PCI DSS validation, confirming they meet the necessary security requirements to protect payment card data. This validation is documented in a PCI Report on Compliance (ROC) for larger businesses or through completed Self-Assessment Questionnaires for smaller merchants.
Who Needs to Comply with Payment Card Industry Compliance?
Any business that stores, processes, or transmits cardholder data must comply with the Payment Card Industry Data Security Standard (PCI DSS). This includes:
- Retailers and brick-and-mortar merchants
- E-commerce businesses and online stores
- SaaS platforms handling payment information
- Payment processors and gateways
- Financial institutions issuing payment cards
- Service providers with access to cardholder data
- Healthcare organizations processing payment information
- Educational institutions accepting tuition payments
The scope of compliance depends on your transaction volume and how you process payments, which determines your PCI DSS compliance level.
PCI DSS Compliance Levels Explained

The Payment Card Industry Data Security Standard establishes four compliance levels based primarily on transaction volume. Understanding your organization’s compliance level is crucial as it determines the validation requirements and assessment procedures you must follow.
Level 1: Enterprise Merchants
- Transaction Volume: Over 6 million card transactions annually across all channels
- Assessment Requirements: Annual on-site assessment by a Qualified Security Assessor (QSA) or Internal Security Assessor (ISA)
- Validation Documentation: PCI DSS Level 1 merchants must submit a PCI Report on Compliance (ROC) annually
- Additional Requirements: Quarterly network scans by an Approved Scanning Vendor (ASV) and penetration testing
- Who Typically Qualifies: Large retailers, global e-commerce platforms, major service providers
PCI DSS Level 1 compliance represents the most rigorous validation process, requiring comprehensive documentation of all security controls and PCI DSS testing procedures. Organizations at this level must maintain continuous compliance rather than point-in-time validation.
Level 2: Mid-Sized Merchants
- Transaction Volume: 1-6 million transactions annually
- Assessment Requirements: Annual Self-Assessment Questionnaire (SAQ) or optional on-site assessment
- Validation Documentation: Completed SAQ, quarterly ASV scans, Attestation of Compliance
- Who Typically Qualifies: Regional retailers, medium-sized e-commerce businesses
Level 3: Smaller Merchants
- Transaction Volume: 20,000-1 million e-commerce transactions annually
- Assessment Requirements: Annual SAQ, quarterly vulnerability scans
- Validation Documentation: Completed SAQ and scan reports
- Who Typically Qualifies: Small online businesses with significant transaction volume
Level 4: Small Merchants
- Transaction Volume: Under 20,000 e-commerce transactions or up to 1 million regular transactions annually
- Assessment Requirements: Annual SAQ (simpler versions based on processing environment)
- Validation Documentation: Completed SAQ, may require quarterly scans depending on processing methods
- Who Typically Qualifies: Small businesses, independent retailers, small online shops
Each card brand (Visa, Mastercard, American Express, Discover, JCB) may have slightly different thresholds for these levels, so merchants should verify their specific compliance level with their payment processor or acquiring bank.
How to Prepare for a PCI Compliance Assessment: Step-by-Step

1. Define Your PCI Scope
Begin by identifying all systems that store, process, or transmit cardholder data, known collectively as the Cardholder Data Environment (CDE). This includes point-of-sale systems, payment applications, databases, and network components that connect to these systems.
To reduce the compliance burden, apply network segmentation to isolate systems that fall within PCI scope. Properly implemented segmentation can significantly reduce assessment complexity by limiting the number of systems subject to PCI DSS requirements. Feroot Security’s solutions help organizations accurately identify and map their cardholder data environment, ensuring complete visibility into your PCI scope.
2. Conduct a Gap Analysis
Evaluate your current environment against PCI DSS requirements to uncover any deficiencies. A thorough PCI DSS risk assessment will identify areas where your security controls fall short of the standard’s requirements.
Address high-risk or non-compliant areas before moving forward with the formal assessment. This proactive approach helps prevent failed audits and costly remediation efforts later in the process.
3. Strengthen Security Controls
Ensure cardholder data is encrypted both in transit and at rest. Implement strong access control measures, including:
- Unique user IDs for all personnel with system access
- Role-based permissions limiting access to only what’s needed
- Two-factor authentication for remote access to the network
- Regular review and updating of access privileges
Maintain centralized audit logs with active monitoring to track and monitor all access to network resources and cardholder data. Implement a robust vulnerability management program that includes regular patching and updates to systems within the cardholder data environment. Feroot Security’s continuous monitoring capabilities provide real-time insights into threats targeting your payment environment, allowing for immediate response to potential vulnerabilities.
4. Test and Monitor
Conduct internal vulnerability scans and penetration tests regularly. The PCI DSS testing procedures require:
- Quarterly internal vulnerability scans
- Quarterly external scans by an Approved Scanning Vendor (ASV)
- Annual penetration testing of both network and application layers
- Testing after any significant infrastructure or application change
Any issues identified should be remediated before the official assessment begins. Document your testing methodology and results as evidence for your assessment.
5. Organize Documentation
Keep all relevant security policies, procedures, and system logs up to date and readily available. Documentation should include:
- Information security policies
- Network diagrams showing cardholder data flows
- System inventory with PCI scope designations
- Vendor management procedures and compliance status
- Incident response plans
- Evidence of security awareness training
Prepare thorough documentation to demonstrate how each PCI control is implemented across your environment. This documentation forms the foundation of your PCI Report on Compliance or Self-Assessment Questionnaire.
6. Train Your Staff
Provide PCI DSS training for employees responsible for handling cardholder data or managing system security. Staff should also be familiar with your organization’s incident response plan and understand their role in maintaining compliance.
Regular security awareness training ensures all employees understand the importance of protecting cardholder data and following security policies and procedures.
Where PCI Assessments Often Fail – What You Should Avoid

- Expanded Scope: Failing to properly segment networks, unnecessarily expanding the compliance scope
- Documentation Gaps: Outdated or missing documentation of security policies and procedures
- Insufficient Scanning: Infrequent vulnerability scanning or failure to remediate identified issues
- Third-Party Oversight: Failure to validate third-party service provider compliance
- Training Deficiencies: Lack of employee training on data security policies
- Default Configurations: Using vendor-supplied defaults for system passwords and security parameters
- Improper Access Controls: Failing to restrict physical access to cardholder data and systems
- Inadequate Monitoring: Not implementing comprehensive logging and monitoring systems
- Neglected Testing: Skipping regular security testing of systems and processes
- Inconsistent Compliance: Treating compliance as a point-in-time event rather than ongoing process
