TL;DR: Manual OSS license review breaks down as dependency counts and release velocity rise, because human checking cannot keep pace with transitive dependencies, version changes, and inconsistent policy decisions, according to LEGIT Security. The governance problem is no longer whether review is possible, but whether teams can enforce compliance continuously without slowing development.
Editorial analysis by NHI Mgmt Group, based on content published by LEGIT Security: “Software License Scanning vs. Manual License Review: The True Cost of Compliance”.
Key questions
Q: How should organisations implement OSS license scanning in CI/CD pipelines?
A: They should treat license scanning as a build control, not a separate review step.
Q: Why does manual license review fail as dependency counts grow?
A: Manual review depends on people keeping pace with package churn, transitive dependencies, and version changes.
Q: What are the signs that open source license tracking is not working well enough?
A: The warning signs are inconsistent license data, missing licenses, and gaps between package manager metadata and source repository records.
Practitioner guidance
- Define license policy in machine-enforceable terms Translate acceptable, restricted and prohibited license categories into rules that scanning tools can apply consistently across repositories and teams.
- Scan transitive dependencies in every build Require automated detection of direct and transitive packages so hidden license obligations are checked before merge, not during periodic audits.
- Route ambiguous licenses to human review Create an exception workflow for dual licensing, custom terms and missing SPDX data so specialists handle only the cases automation cannot resolve.
Bottom line: Manual OSS license review becomes unreliable once dependency counts and version churn exceed human review capacity.

Continuous policy enforcement is now the real compliance problem. Manual review assumes license decisions can be made once and left in place, but modern dependency trees change too quickly for that to hold. The governance gap is not a lack of review intent, it is the inability to enforce policy every time a package or version changes. Practitioners should therefore treat license governance as a runtime control inside the delivery pipeline.
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.
A question worth separating out:
Q: What happens when a dependency changes license after approval?
A: The earlier approval may no longer be valid, even if the package name stays the same. That creates governance drift, because the decision recorded at review time no longer matches the current risk. Automated rescanning is needed so version changes trigger a fresh policy evaluation before the updated dependency is trusted.
