TL;DR: Software composition analysis scans open source and third-party components to produce an SBOM, flag known vulnerabilities, and support license compliance, audit readiness, and continuous monitoring across the SDLC, according to OXSecurity. For application security teams, the issue is not just detection but keeping dependency risk visible as code, packages, and build artifacts change.
Editorial analysis by NHI Mgmt Group, based on content published by OXSecurity: “What is an SCA Scan?”.
Key questions
Q: What breaks when software composition analysis does not identify all dependencies accurately?
A: When SCA misses components, security teams can receive an incomplete bill of materials and underestimate exposure.
Q: Why do vulnerable open source components create application risk?
A: They create risk because third-party code inherits the trust of the application even when the team did not author it.
Q: How do you know if SCA is actually working?
A: SCA is working when the SBOM stays current, vulnerable dependencies are identified before release, and findings are prioritised by exploitability rather than volume.
Practitioner guidance
- Instrument SCA at every build stage Run scans at commit, build, and deployment points so the SBOM updates as dependencies and artifacts change.
- Triage findings by runtime reachability Prioritise vulnerable components that are actually loaded at runtime or reachable from application paths instead of treating every CVE equally.
- Maintain an auditable SBOM baseline Keep a current component inventory that records version, origin, and license data for every shipped application release.
Bottom line: Software composition analysis is now part of application governance because dependency inventories, SBOMs, and vulnerability data have to stay aligned as code changes.

Dependency visibility is now a governance control, not a tooling feature. Once open source components are embedded across build pipelines, the question is no longer whether teams can scan them, but whether they can maintain trustworthy inventory and decision-making over time. That is why SCA belongs in application governance alongside vulnerability management and release approval. Practitioners should treat the SBOM as a control object, not a report artifact.
A few things that frame the scale:
- Internal repositories are 6x more likely to contain secrets than public ones (32.2% vs 5.6%), contradicting the assumption that private repos are safe, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: How should security teams decide between SAST and SCA?
A: Use SAST for code your organisation wrote and SCA for software it imported. If the application has both custom logic and third-party packages, you need both controls because they answer different questions. The correct decision model is coverage, not replacement, especially when runtime exposure and privilege change the impact of each finding.
