Navigating PCI DSS 4.0 Compliance: A Responsibility Matrix for ISVs

In the ever-evolving landscape of payment processing and data security, PCI DSS compliance remains a cornerstone for businesses handling cardholder data. As we prepare for the upcoming updates to the PCI DSS standard, effective April 1, 2025, the need for clarity in shared responsibilities among stakeholders has never been greater.

Today, I took a step to address this need by reviewing and creating a PCI DSS Responsibility Matrix that outlines the obligations of key stakeholders:

  • ISV Partner (Independent Software Vendor)
  • Salesforce (as the platform provider)
  • Payment Provider
  • Client

This effort resulted in a comprehensive document with 340 rows, meticulously mapping compliance responsibilities for each party. I’m sharing this matrix for free to help others streamline their compliance efforts.

Disclaimer:
This matrix is based on my interpretation of PCI DSS requirements as they apply to specific implementation scenarios. It does not guarantee accuracy or completeness for all use cases, particularly for implementations that differ from the example described. Please use this matrix as a point of reference and adapt it to fit your unique requirements and approach.

Why PCI DSS Compliance Matters

For those unfamiliar, PCI DSS (Payment Card Industry Data Security Standard) is a set of security standards designed to protect cardholder data. Compliance is not just a best practice; it’s a requirement for any entity that processes, stores, or transmits payment card information. Non-compliance can lead to:

  • Significant financial penalties.
  • Damage to brand reputation.
  • Potential loss of payment processing privileges.

According to Verizon’s 2023 Payment Security Report, businesses adhering to PCI DSS experienced fewer data breaches compared to those that didn’t. Learn more about the PCI DSS impact here.

The ISV Perspective

From an ISV partner perspective, our compliance responsibility is often limited, especially when leveraging external payment providers. In this case, our application, built on Force.com, utilizes a payment provider connection via iframe. This places us in the SAQ A category, meaning:

  • Minimal responsibility for securing cardholder data.
  • Focused compliance on ensuring the iframe and environment meet basic security requirements.

However, role clarity remains critical, as clients often assume the ISV has greater responsibilities than is accurate. This matrix addresses such misconceptions.

Key Highlights of the Responsibility Matrix

  1. Role-Specific Clarity:

    • Salesforce’s platform-level responsibilities for securing infrastructure.
    • The payment provider’s obligations for transaction security and data encryption.
    • Client-side responsibilities for maintaining secure user interactions.

  2. Adaptability to PCI DSS v4.0 Updates:
    The matrix is forward-looking, designed to align with the updated PCI DSS format launching in April 2025.

  3. Practical Usage for ISVs and Clients:
    This document simplifies audit preparation and collaboration by clearly defining boundaries and expectations.

Final Thoughts

Compliance is a shared responsibility, and clear communication is the foundation of success. Whether you’re an ISV, a client, or a consultant, understanding your role in PCI DSS compliance ensures smoother audits, stronger partnerships, and better outcomes for all stakeholders.

From JDK to ICU Locale Formats: Adapting Salesforce Applications for the Next Generation of Formatting

Salesforce is significantly changing its underlying date, time, and number formatting engines. With the Summer ’25 release , Salesforce will move from JDK (Java Development Kit) formatting to ICU (International Components for Unicode) formatting.

Navigating Lightning Web Security (LWS) Restrictions with Iframes (CORS)

With the Salesforce Spring ‘25 release , new Lightning Web Security (LWS) restrictions are causing headaches for developers who use iframes in their applications. If you’ve encountered the dreaded error: Access to XMLHttpRequest at 'https://m.stripe.com/6' from origin 'null' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header has a value 'https://m.stripe.network' that is not equal to the supplied origin. POST https: //m.stripe.com/6 net::ERR_FAILED 200 (OK) You’re not alone. This issue isn’t just Stripe-specific -  it can occur with any iframe-based integration under the new LWS rules. Let’s break down what’s happening and how to adapt. What Changed in Spring ‘25? According to the Salesforce release notes : Previously, LWS allowed access to iframe elements if they shared the same origin as the parent page. Now , all iframes with an explicit src attribute are subject to cross-origin restrictions, even if their source ma...
