Frequently Asked Questions
PCI DSS compliance means meeting the requirements for protecting cardholder data as you process, transmit and store it.
Any organisation that stores, processes or transmits payment card data must comply. This includes merchants, service providers, fintechs, banks and SaaS platforms.
Card schemes, acquiring banks, processors and your contracts require PCI DSS compliance whenever you handle card data.
Non-compliance can lead to financial penalties, closer monitoring, withdrawal of payment privileges, legal liability and reputational damage.
Validation covers readiness review, gap remediation, evidence preparation, assessment by a Qualified Security Assessor and issuance of a Report on Compliance (RoC) and Attestation of Compliance (AoC).
Cost depends on assessment scope, organisation size, remediation workload, infrastructure complexity and your merchant or service provider level.
Most engagements take 60 to 180 days, depending on readiness and remediation needs.
Version 4.0 is the current standard. It sets stronger controls for authentication, governance integration, risk management and continuous compliance.
Twelve requirements cover network security, encryption, access control, monitoring, vulnerability management, secure coding and governance.
A QSA independently assesses your compliance, validates evidence, performs testing and issues an attestation report.
A QSA gives you objective validation, correct interpretation of the requirements and wider acceptance by banks and card schemes.
Yes. Smaller merchants usually validate compliance through the relevant Self Assessment Questionnaire.
The SAQ is a structured self-validation tool. It lets eligible organisations attest compliance without a full external assessment.
Selection depends on your payment channels, card data flows, technology architecture and storage practices.
Service providers can support the work, but responsibility for compliance stays with the organisation that handles cardholder data.
No. Cloud providers share responsibility, but you remain accountable for security and compliance outcomes.
It is a formal assessment. An accredited QSA evaluates your controls, documentation and processes.
Compliance is validated annually and depends on ongoing evidence maintenance and review.
Approved Scanning Vendors run these quarterly scans to find external vulnerabilities that affect card environments.
Validation needs architecture diagrams, policies, procedures, logs, evidence records, testing results and governance artefacts.
Only where tokenisation meets irreversibility criteria. Otherwise PCI DSS requirements still apply.
Scope covers every system, person and technology that touches or affects cardholder data security.
Through segmentation, outsourcing, encryption, tokenisation and architectural redesign.
Yes. You must encrypt card data in storage and in transit.
Common tools include SIEM, MFA platforms, logging, DLP, firewall management, vulnerability scanning, patching and compliance automation.
Yes. Annual internal and external penetration testing is mandatory.
Card brands, issuing banks, payment processors and acquiring institutions enforce it.
Levels are set by transaction volume. Higher levels require a full assessment, while lower levels allow self-assessment.
Yes. Accountability for cardholder data stays with the merchant, whatever you outsource.
PCI DSS touches technology, processes, governance, controls, roles, evidence workflows and culture, which makes it multidimensional.
CyberSigma provides gap assessments, remediation advisory, documentation support, audit readiness testing, QSA review support and compliance lifecycle management.
Yes. It strengthens access control, monitoring, risk governance and incident handling.
Yes. If card data is handled or transmitted, or affects transaction security, PCI DSS applies.
Yes. Legal, HR, risk, operations, procurement and leadership all shape governance and policy compliance.
Evidence is verifiable artefacts that show your controls operate, such as logs, reports, approvals, screenshots or configurations.
Yes. You must record, monitor and review security logs.
Testing confirms that network segmentation isolates cardholder data environments from other systems.
They include banking, fintech, SaaS, telecom billing, e-commerce, retail, hospitality, BPO payments and service providers.
Yes. Validated compliance builds market credibility, speeds client onboarding and improves contractual eligibility.
