PCI Secure Software Lifecycle (S-SLC) Overview
PCI S-SLC (Secure Software Lifecycle)
The PCI Secure Software Lifecycle (PCI S-SLC) standard helps software vendors embed security into every phase of development. SISA helps organizations align their software development lifecycle with PCI S-SLC requirements, ensuring secure design, development, testing, release, and maintenance of applications used within the payment ecosystem.
TABLE OF CONTENT
Why it matters
Securing Software in the Payments Ecosystem Requires More Than Code Reviews
Payment software vendors face several challenges in embedding security throughout the development lifecycle, including:
Inconsistent secure development practices across engineering teams
Lack of governance and documentation around secure SDLC processes
Difficulty aligning internal development workflows with PCI S-SLC expectations
Limited visibility into vulnerabilities introduced during development and release cycles
Challenges preparing structured evidence for PCI S-SLC validation
Our Approach
A Practical, Structured Path to PCI S-SLC Validation
SISA follows a practical and PCI SSC aligned approach to help organizations strengthen their secure software development lifecycle while maintaining development agility.
Evaluate whether PCI S-SLC applies to your organization and assess overall readiness against S-SLC requirements.
Assess policies, procedures, and governance covering secure architecture, coding practices, release management, and vulnerability handling.
Identify gaps across governance, secure development practices, training programs, and testing processes.
Provide actionable recommendations to strengthen SDLC controls while aligning with existing development workflows.
Support organizations through PCI S-SLC assessments, evidence preparation, and validation readiness.
