Securing the Software Supply Chain for a Leader in Industrial Automation - CRA-Ready and Resilient by Design

Impact at a Glance 

A secure software supply chain for a leading industrial automation company, aligned with the emerging requirements of the Cyber Resilience Act (CRA) and compliant with GDPR, IEC 62443, and ISO 27001. The strategic shift resulted in up to a 75% reduction in software vulnerabilities, accelerated release cycles by up to 80%, and provided full component transparency via Software Bills of Materials (SBOMs) and verifiable artifact integrity through the SLSA framework. 

 

Initial Situation & Challenge  

Like many modern industrial manufacturers, this company operated in a complex, hybrid-cloud environment supporting both IT and Operational Technology (OT). Development of software for their automation and control systems was distributed across numerous internal teams and external suppliers, each with different tools and varying levels of security awareness. This created a classic scenario where the complexity of the software supply chain had outpaced security governance. Critical security gaps were identified, including an unclear Software Bill of Materials (SBOM), inconsistent security controls across teams, and unsecured CI/CD pipelines lacking secure artifact management and code signing. 

 

What Was at Stake 

Without a strategic change, the company faced significant and escalating risks that threatened its core operations: 

• Regulatory Exposure: A high risk of non-compliance with existing regulations like GDPR, potential audit failures against ISO 27001, and an inability to meet the stringent new requirements of the EU’s Cyber Resilience Act (CRA) and the IEC 62443 standard for industrial control systems. 
• Supply Chain Vulnerabilities: An inability to produce a Software Bill of Materials (SBOM) meant they were blind to vulnerabilities in their open-source and commercial dependencies. Lacking verifiable software provenance, their products were exposed to malware injection and tampering attacks that could directly impact industrial processes. 
• Operational Chaos: Inconsistent and insecure CI/CD pipelines created friction between teams and led to security gaps. The lack of automated guardrails meant that vulnerabilities were often discovered late in the cycle, causing release delays of five or more days. 
• Business Threat: A compromised software release could lead to the disruption of manufacturing operations, production downtime, the compromise of Operational Technology (OT) systems, and even risks to physical safety, causing irreparable damage to the brand’s reputation for reliability and security. 

 

Our Approach: How We Tackled It 

We implemented a security-by-design framework by conducting a thorough threat assessment and re-architecting the entire software delivery lifecycle. The approach was transformational, not just technical: 

• Proactive Threat Modeling & Architecture Reviews: The engagement began with a deep analysis of potential attack vectors using the MITRE ATT&CK for Supply Chain framework and a review of critical interfaces (SSO, WAFs, IAM) to prioritize risks. 
• Achieving Transparency with SBOMs: We mandated the generation of a Software Bill of Materials (SBOM) for every application. This created a complete inventory of all software components, enabling automated vulnerability scanning and rapid response to newly discovered threats. 
• Hardening the Build Pipeline with SLSA: To protect against tampering, we implemented the Supply-chain Levels for Software Artifacts (SLSA) framework. This involved hardening the CI/CD environment with Zero Trust principles (MFA, RBAC), enforcing cryptographic code signing, and creating verifiable software provenance. 
• Establishing Governance by Design: Risk-based security pipelines (guardrails) were defined and integrated with automated tools for Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), and Software Composition Analysis (SCA). A trusted container and code repository was established to standardize and control deployments. 
• Implementing Runtime Protection: To ensure continuous security, real-time monitoring was established by integrating a SIEM for log analysis and deploying AI-driven behavioral anomaly detection. A SOAR platform was introduced for automated incident response, enabling the system to quarantine compromised builds or block malicious injections. 
• Structured Vendor Risk Management: A formal vendor security governance model was established, using an automated assessment framework to ensure all third-party suppliers complied with SBOM tracking and security best practices. 

 

Measurable Results from the Partnership 

The three-month engagement established a secure foundation for the company’s software development, with the partnership being extended to drive long-term security maturity: 

• Dramatically Faster Software Releases: Security-related delays were reduced from over five days to under 24 hours per release, accelerating cycles by up to 80%. 
• Significant Reduction in Vulnerabilities: Automated scanning and validation detected a vast majority of vulnerabilities before deployment, reducing critical findings by up to 75%. 
• Automated Compliance & Reduced Risk: The new framework ensured adherence to regulatory requirements, successfully passing audits with no violations identified during audits, and reduced third-party risks by 60%. 
• Verifiable Artifact Integrity: Critical applications achieved SLSA Level 2, providing verifiable provenance and significantly strengthening protections against tampering in the build and release process. 
• Built In-House Security Know-How: The client’s teams were equipped with the expertise to maintain and evolve their software supply chain security practices, anchoring security sustainably within their processes.
