PCI DSS and SOX are two of the most consequential mandatory compliance regimes — one governing how payment card data is protected, the other how US public companies ensure the integrity of their financial reporting.
Both carry real penalties for failure, and both are common drivers of GRC investment because they demand documented, tested controls.
This page is part of our GRC frameworks hub. For the broader discipline, see our complete guide to governance, risk, and compliance.
PCI DSS: protecting payment card data
The Payment Card Industry Data Security Standard (PCI DSS) is a mandatory standard, maintained by the PCI Security Standards Council, that applies to any organization that stores, processes, or transmits cardholder data. It is contractual rather than governmental — enforced by the payment card brands and acquiring banks — but non-compliance can mean fines, higher transaction fees, or loss of the ability to process cards.
PCI DSS is organized around a set of control requirements covering network security, data protection, access control, monitoring, and security testing.

The current generation, PCI DSS v4.0 (and its v4.0.1 update), emphasizes continuous security, customized implementation approaches, and stronger authentication. Validation requirements scale with transaction volume, from self-assessment questionnaires for smaller merchants to formal assessment by a Qualified Security Assessor for the largest.
SOX: integrity of financial reporting
The Sarbanes-Oxley Act (SOX) is a US federal law enacted in 2002 in response to major accounting scandals.
It requires public companies to establish, document, and test internal control over financial reporting (ICFR), with executives personally certifying the accuracy of financial statements. SOX Section 404 — the requirement to assess and report on ICFR — is where most GRC effort concentrates, because it demands an auditable trail of controls and testing. SOX programs are typically built on the COSO internal control framework.
How PCI DSS and SOX fit a GRC program
Both regimes exercise the compliance and audit disciplines of GRC intensively. PCI DSS demands continuous control monitoring and security testing; SOX demands documented, tested internal controls and a clear evidence trail.
Because both rely on the same underlying controls an organization already maintains, they are prime candidates for control cross-mapping — supported by the platforms in our compliance management software and audit management software directories.
Frequently asked questions
What is PCI DSS?
PCI DSS is the Payment Card Industry Data Security Standard — a mandatory set of security requirements for any organization that stores, processes, or transmits payment card data, enforced by the card brands and acquiring banks rather than by government.
What is SOX compliance?
SOX compliance means meeting the requirements of the US Sarbanes-Oxley Act, particularly establishing, documenting, and testing internal control over financial reporting, with executive certification of financial statements. It applies to US public companies.
Who needs to comply with PCI DSS?
Any organization that handles payment card data — merchants, processors, and service providers — must comply, with validation requirements scaling by transaction volume.
Is SOX a framework?
SOX is a law, not a framework, but compliance is typically implemented using a control framework such as COSO for internal control over financial reporting.
