Direct Answer
What is PCI DSS?
The Payment Card Industry Data Security Standard (PCI DSS) is a global security standard that any organisation storing, processing, or transmitting payment-card data must follow to protect cardholder information. Maintained by the PCI Security Standards Council, the current version is v4.0.1 (the v4.x line; v3.2.1 retired in 2024), and it sets out 12 core requirements across network security, encryption, access control, monitoring, and security policy. How you validate compliance depends on your transaction volume: smaller merchants typically complete a Self-Assessment Questionnaire (SAQ), while the highest-volume merchants and service providers undergo a full Report on Compliance (RoC) assessed on-site by a Qualified Security Assessor (QSA).

Frequently Asked Questions
Common questions on PCI DSS scope, validation, and the v4.0.1 requirements.
Who needs to comply with PCI DSS?
Any organisation that stores, processes, or transmits cardholder data must comply — including e-commerce platforms, payment gateways and PSPs, retailers and hospitality businesses with point-of-sale systems, SaaS and hosting providers in the payment flow, and fintech or digital-wallet companies. Even if you outsource card processing, you remain responsible for the parts of your environment that touch card data.
What is the difference between an SAQ and a Report on Compliance (RoC)?
A Self-Assessment Questionnaire (SAQ) is a validation document that eligible lower-volume merchants and service providers complete themselves to attest to PCI DSS compliance. A Report on Compliance (RoC) is a formal, detailed assessment performed on-site by a Qualified Security Assessor (QSA) and is required for Level 1 merchants and many service providers. The right path depends on your merchant level and how you accept payments — there are several SAQ types (A, A-EP, D, etc.) for different scenarios.
What is a QSA and do I always need one?
A Qualified Security Assessor (QSA) is a company qualified by the PCI Security Standards Council to perform on-site PCI DSS assessments and produce a Report on Compliance. You need a QSA when a RoC is required (typically Level 1). Lower-level merchants can usually self-validate via an SAQ, though a QSA or advisor often helps scope the environment, run the gap assessment, and prepare evidence. Quarterly external scans must be run by an Approved Scanning Vendor (ASV).
What changed in PCI DSS v4.0 / v4.0.1?
PCI DSS v4.0 (with the v4.0.1 revision) replaced v3.2.1, which was retired in 2024. Key changes include a stronger focus on continuous security rather than point-in-time compliance, more flexibility through a new "customised approach" to meeting control objectives, expanded multi-factor authentication requirements, and enhanced requirements around scripts on payment pages and targeted risk analyses. Several future-dated requirements became mandatory in 2025.
How long does PCI DSS compliance take and what does it cost in India?
For most Level 2–4 merchants, implementation runs about 2–6 months depending on environment complexity and how much remediation is needed; Level 1 programs can take 6–9 months. Indicative India pricing for consulting and implementation typically falls under ₹5 lakh, with separate annual validation costs. Because PCI DSS shares roughly 70% of its controls with ISO 27001 and SOC 2, running them together meaningfully reduces total effort and cost.
Working with Tranquility Cybersecurity
How TCSA supports your PCI DSS program
Tranquility Cybersecurity helps Indian merchants and service providers scope their cardholder-data environment, close gaps against the 12 requirements, prepare SAQ or RoC evidence, coordinate QSA and ASV engagements, and stand up the ongoing controls PCI DSS v4.0.1 expects. Because PCI DSS overlaps heavily with ISO 27001 and SOC 2, we often run them together.
