What is a Software Supply Chain Maturity Assessment? A Complete Guide for 2025
Software supply chain security has emerged as a top priority for organizations in 2025. With increasing threats from supply chain attacks, tighter compliance regulations, and the widespread adoption of cloud-native technologies, engineering teams, security professionals, and CTOs are looking for robust strategies to safeguard their environments. One essential step in this journey is conducting a Software Supply Chain Maturity Assessment. In this guide, we’ll define what a maturity assessment involves, why it matters, and how to approach one for your organization.
Understanding the Software Supply Chain
The software supply chain encompasses all the processes and tools used to develop, build, package, distribute, and update software. This chain includes source code repositories, CI/CD pipelines, third-party dependencies, container registries, artifact stores, and deployment systems. Every step introduces potential risks: from upstream vulnerabilities in open-source libraries to insecure build pipelines and tampering in automated deployments.
With notable incidents such as the SolarWinds breach, and the exponential growth of software dependencies, organizations need systematic approaches to identify, evaluate, and mitigate software supply chain risks.
What Is a Software Supply Chain Maturity Assessment?
A Software Supply Chain Maturity Assessment is a structured evaluation of an organization’s processes, tools, policies, and cultural practices related to supply chain security. Its goal is to measure how effectively the organization manages risks tied to sourcing, integrating, building, and delivering software. The assessment helps pinpoint where your current practices stand compared to industry standards and outlines step-by-step pathways toward improvement.
Core Assessment Focus Areas
A comprehensive assessment typically covers:
- Governance and Policy: Are there defined policies for third-party software, SBOM (Software Bill of Materials), and vulnerability management?
- Inventory and Visibility: Can the organization reliably track all software assets, dependencies, and components?
- Build and Release Security: How secure are the CI/CD pipelines, build servers, and artifact repositories?
- Dependency Management: Are dependencies regularly reviewed, updated, and scanned for vulnerabilities?
- Monitoring and Response: How quickly can you detect, triage, and respond to supply chain incidents?
- Compliance Alignment: Does your organization align with SSDF (NIST Secure Software Development Framework), SLSA (Supply Chain Levels for Software Artifacts), CIS Benchmarks, or other regulatory frameworks?
Most assessments leverage industry standards as reference points. For example, the SLSA framework provides progressive stages (Level 1–4) for supply chain security implementation. The SSDF from NIST standardizes practices for secure software development.
Why Is Maturity Assessment Critical in 2025?
1. Escalating Supply Chain Attacks
According to recent reports, over 60% of software attacks in 2025 exploited the supply chain, often via compromised third-party dependencies or tampered build processes. Organizations without maturity assessments are less likely to catch these risks before they manifest in production.
2. Compliance Requirements
Regulatory demands such as the U.S. Executive Order on Improving the Nation’s Cybersecurity require organizations to produce SBOMs, enforce code provenance, and secure build pipelines. A maturity assessment maps out gaps and helps maintain ongoing compliance.
3. Reputation and Risk Management
Supply chain breaches not only cause downtime and data loss but harm brand reputation. Automated tools and improved processes identified during a maturity assessment minimize exposure and highlight investment priorities.
The Assessment Process: Step-by-Step
A typical supply chain maturity assessment proceeds as follows:
1. Stakeholder Engagement
The assessment begins by assembling a cross-functional group including DevOps engineers, software developers, security, compliance, IT, and leadership. This ensures broad coverage and organizational buy-in.
2. Inventory & Mapping
Document all software assets, repositories, build environments, CI/CD infrastructure, and external dependencies. Use automated inventory tools where possible. For example:
# Example: List all third-party dependencies in a Node.js project
npm list --all
Link inventory back to business-critical applications and compliance requirements.
3. Policy and Standards Review
Evaluate existing policies against industry benchmarks. Reference frameworks such as:
Identify policy gaps, e.g., missing SBOM requirements or absent vulnerability scanning cadence.
4. Pipeline and Artifact Security Analysis
Analyze the build pipeline for weak points. For example:
- Are build servers isolated and patched?
- Is artifact provenance tracked using cryptographic verification?
- Is automated scanning for vulnerabilities and policy violations integrated in CI/CD?
Sample configuration for enabling SBOM generation with GitHub Actions:
name: Generate SBOM
on:
push:
branches: [main]
jobs:
generate-sbom:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- name: Generate SBOM
run: syft . -o sbom.json
5. Dependency and Vulnerability Management
Assess how you track and remediate vulnerabilities in third-party components. Are there automated scanners (e.g., Snyk, Trivy, Dependabot) integrated into your workflow?
# Scan Docker images for vulnerabilities
trivy image myapp:latest
Establish routines for ongoing patching and update cadence.
6. Incident Detection & Response
Evaluate capabilities for detecting and responding to supply chain attacks, including alerting, forensics, and corrective actions. Test incident playbooks to ensure coverage.
7. Scoring & Roadmap
Benchmark findings against maturity models (e.g., SLSA levels). Deliver a prioritized roadmap outlining actionable improvements, quick wins, and strategic investments.
Actionable Outcomes
A finished assessment yields these benefits:
- Gap Analysis: Clarity on strengths and weaknesses across people, process, and technology.
- Improvement Plan: Roadmap to elevate maturity, e.g., automating SBOM generation, adopting stricter policy enforcement, securing CI/CD pipelines.
- Executive Buy-In: Quantitative scoring and compliance alignment for board-level discussions.
- Audit Readiness: Documentation and evidence for regulatory audits and certification processes.
Real-World Case Study: Leading Fintech’s Journey
A fintech company with over 200 microservices underwent a supply chain maturity assessment after noticing an uptick in dependency vulnerabilities. Their evaluation revealed gaps in SBOM coverage and inconsistent CI/CD security controls. By implementing automated SBOM generation and container scans in their pipelines, the organization reduced median response time to new critical CVEs by 80%, slashed manual intervention, and met all compliance deadlines ahead of schedule.
How to Get Started
Organizations should begin by selecting a framework (e.g., SLSA, SSDF) and partnering with experts who can tailor assessments to their unique environment. Software like Quaerens Perspicax and Probatus Suite can automate assessments, generate SBOMs, and orchestrate vulnerability management at scale.
