SAQs (Self-Assessment Questionnaires) in the PCI DSS v4.0.1 Bulletin offer detailed instructions and criteria for merchants to evaluate and validate their adherence to Payment Card Industry Data Security Standard (PCI DSS) requirements

SAQs provide guidelines for merchants to self-assess their compliance with PCI DSS requirements

SAQs categorize merchants based on their payment processing methods and volumes, providing tailored questionnaires for each category. These questionnaires cover various security controls such as network protection, encryption, access management, and vulnerability management. Merchants are required to complete the SAQ that aligns with their specific circumstances and may also need to undergo additional vulnerability scans or penetration testing. Compliance with the PCI DSS standards is crucial for safeguarding payment card data and maintaining trust with customers and stakeholders.
