Modern embedded devices run on complex, multi-layered software stacks - but what's actually inside them is often unclear.
Software Bills of Materials (SBOMs) are meant to provide transparency. In practice, they are frequently incomplete, outdated, or unreliable. When you can't see your components clearly, vulnerability assessment becomes slow, uncertain, and operationally expensive.
A perfect SBOM is unrealistic in embedded systems - but meaningful improvement is achievable. PCA Cyber Security's Software Composition Analysis (SCA) & SBOM Validation approach starts with Red Team-style reconnaissance, firmware analysis, and reverse engineering to reconstruct the true software composition of your device. The result is an evidence-backed component map - not just vendor documentation - enabling precise, continuously maintained security.
The Challenges of SCA & SBOM Validation
Embedded devices - including payment terminals, ATMs, ECUs, PLCs and more - rely on complex software stacks, yet organizations often lack a clear view of what is actually deployed. Even when SBOMs are available, they are frequently incomplete, outdated, or inaccurate. Heterogeneous build environments, undocumented dependencies and supply chain opacity further limit transparency. As a result, assessing exposure to newly disclosed vulnerabilities becomes slow and uncertain, while maintaining accurate SBOMs across the device lifecycle remains technically demanding and resource-intensive.
How can PCA Cyber Security help you?
We don’t rely on existing SBOMs - we rebuild them from the firmware itself. By reverse engineering the actual binary running on your device, we reconstruct its software composition: component, library, dependency, documented or not. This evidence-backed inventory feeds directly into vulnerability intelligence, so when a new CVE is disclosed, you know immediately whether your devices are affected- without chasing vendors for confirmation.
The result is continuous, evidence-based visibility into your software supply chain. Not a paper exercise for compliance. Not a vendor's assurance taken on trust. An engineering-grade foundation for security decisions.
Objective of the Service
Conventional SBOMs depend on vendor documentation, which is frequently incomplete, outdated, or misleading. Our service breaks that dependency entirely.
We reverse-engineer your device firmware to reconstruct a verified inventory of software components - including libraries, modules, and third-party code that conventional approaches miss. This validated foundation enables two things: rapid impact assessment when new vulnerabilities emerge, and proactive security management across the entire device lifecycle, from procurement through decommissioning.
Your visibility remains reliable as systems evolve, because it's grounded in evidence extracted from the device itself - not is a document someone handed you.
Deliverables
Security does not end at certification. We support you across the full device lifecycle - from pre-deployment assessment through ongoing vulnerability monitoring as new threats emerge. , that is why we support our clients at the most important lifecycle stages.

Business Benefits of Software Composition Analysis & SBOM Validation
Effective
Vulnerability Monitoring
Know immediately when a new CVE affects You. Your verified component inventory means no chasing vendors for confirmation. When a vulnerability is disclosed, you determine exposure in hours, not weeks.
Actionable
Vulnerability Management
Prioritize remediation with evidence, not assumptions. Focus engineering resources on confirmed risks. PCA Cyber Security’s binary-level validation eliminates the noise of vulnerabilities that don't actually apply to your device.
Enhanced Lifecycle
Management
Maintain visibility across the full product lifecycle. From procurement through field deployment to decommissioning, your component visibility remains current - even as firmware updates and patches are applied.
Reduced Operational Costs
Stop burning engineering cycles on manual SBOM verification, investigating phantom vulnerabilities, or patching components you don't actually have. Focus only on what matters.
Stronger Compliance Readiness
Simplify PCI and regulatory compliance. Provide auditors with validated SBOM data and documented evidence of software composition - not just a vendor's spreadsheet accepted on faith.
Removed Vendor
Dependency
Verify third-party components independently. Your security posture should not depend on a supplier's willingness to disclose what's inside their product.
