TL;DR: Modern software needs hundreds of direct and transitive packages, so manual SBOM tracking cannot keep up with release and compliance pressure, according to Cycode. Build-time inventory gives teams current component data for vulnerability triage, supplier review, and audit evidence.

Editorial analysis by NHI Mgmt Group, based on content published by Cycode: “SBOM Automation: Tools and Guide”.

Key questions

Q: Why does stale component inventory create compliance and security risk?

A: Stale inventory hides the components that were actually shipped, so teams cannot map new vulnerabilities, license obligations, or policy violations back to the affected build quickly.

Q: How do security teams know if SBOM ingestion and dependency scanning are actually working?

A: Look for coverage across the build lifecycle, not just occasional scans.

Q: What breaks when SBOMs are not kept current?

A: An outdated SBOM weakens vulnerability triage, supplier review, and incident response because it no longer reflects what is actually deployed.

Practitioner guidance

  • Implement build-time SBOM generation Generate SPDX or CycloneDX SBOMs automatically during CI/CD so each build produces an artifact-level inventory without manual export steps.
  • Correlate SBOMs with vulnerability and reachability data Pair component inventories with vulnerability and reachability context so teams can focus on exploitable risk rather than raw dependency counts.
  • Extend coverage to transitive dependencies Test whether your current process captures nested packages, containers, and multi-language stacks instead of only top-level manifests.

Bottom line: Manual SBOM handling cannot keep pace with modern dependency depth, so teams need an automated inventory tied to the build.

SBOM automation has become a governance control, not a documentation exercise. Once software is assembled from hundreds of direct and transitive components, a manually maintained list is too stale to support release decisions or risk acceptance. The practical shift is that component visibility now belongs inside the build and delivery process, where the artifact is formed.

A few things that frame the scale:

  • Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
  • Software supply chain attacks were projected to cost organisations $60 billion in 2025.

A question worth separating out:

Q: What should organisations prioritise first in SBOM programmes?

A: They should prioritise build-time generation over later cataloguing, because the inventory must reflect the artifact at the moment it is created. After that, the next priority is coverage for the systems that create the most drift, especially transitive dependencies and container builds.
