PCI SSF Advisory Services
Expert guidance to help you prepare responsibly for PCI Software Security Framework (SSF) validation across the software lifecycle.
Overview / Context
The PCI Software Security Framework (SSF) is a set of standards established by the PCI Security Standards Council (PCI SSC) to improve the security of payment software. It applies to software that stores, processes, or transmits payment data and replaces the legacy Payment Application Data Security Standard (PA-DSS).
PCI SSF introduces broader coverage and a modernized approach to software security by addressing both how payment software is built and how it is deployed and maintained. Organizations developing or distributing payment software are increasingly expected by customers, partners, and acquirers to demonstrate alignment with PCI SSF requirements.
Many organizations struggle to understand applicability, scope, and expectations under PCI SSF — particularly when navigating the Secure Software Standard, Secure Software Lifecycle (Secure SLC) Standard, and optional modules.

Why This Matters First
Before engaging in validation activities, organizations must clearly understand:
Which applications and development processes are in scope
Which SSF standards and modules apply
What evidence and controls are expected by independent validators
Early clarity reduces uncertainty, avoids rework, and supports defensible outcomes aligned with PCI SSC requirements. A structured, readiness-focused approach helps organizations address risk before entering formal validation.
How the Approach Works
RSI Security supports PCI SSF readiness through a structured advisory approach.
RSI Security
Initial Discovery
Understand software architecture, development practices, and deployment models.
RSI Security
Scope & Applicability Review
Determine which SSF standards and modules apply.
RSI Security
Readiness & Gap Analysis
Assess alignment with Secure Software and Secure SLC requirements.
RSI Security
Documentation & Evidence Preparation
Support development of required artifacts and evidence.
RSI Security
Remediation Support
Assist with addressing identified gaps.
RSI Security
Ongoing Alignment Support
Help maintain alignment as software and threats evolve.
Independent PCI SSF validation is performed by third-party validation bodies.
Framework / Model Overview
The PCI Software Security Framework consists of two standards:
Secure Software Standard
Focuses on protecting payment data within deployed software.
Secure Software Lifecycle (Secure SLC) Standard
Focuses on secure software development and maintenance practices.
The Secure Software Standard also includes optional modules that introduce additional control objectives based on application design and functionality. These modules are scope-dependent and validated only when applicable.
This overview is provided for educational purposes and does not imply validation outcomes.
Why Preparation & Rigor Matter
Organizations That Approach PCI SSF Late or Without Sufficient Preparation Often Encounter
- Validation delays and rework
- Increased operational and remediation costs
- Contractual or partner friction
- Elevated risk of security gaps
A deliberate, well-documented readiness process supports efficient validation, reduces business disruption, and strengthens overall software security posture.
Key Benefits
Clear understanding of PCI SSF expectations and applicability
Reduced uncertainty during independent validation
Fewer surprises and less remediation rework
Defensible documentation and evidence
Improved stakeholder confidence
Sustainable, repeatable software security practices
RSI Security's Role
RSI Security provides independent PCI SSF advisory and readiness services designed to help organizations prepare for third-party validation.
Our Role Includes:
- Scope and applicability analysis
- Readiness and gap assessments
- Documentation and evidence support
- Remediation planning and advisory guidance
RSI Security does not perform PCI SSF validation or certification activities. Clients remain free to select any independent PCI SSF validation body.
RSI Security is recognized by PCI SSC as an Approved Scanning Vendor (ASV) and Qualified Security Assessor (QSA) for PCI DSS services.
