Monorepo Dependency Security — Vulnerability Scanning Across Packages

Short summary

Monorepos combine multiple packages and services in one repository, creating complex dependency security challenges that demand multi-level scanning. Security teams must examine root lockfiles, workspace-specific manifests, and SBOMs together—scanning only one source risks missing vulnerabilities. Dependency hoisting adds complexity; the best approach combines fast root scans with per-workspace accountability and scheduled full scans.

• •Monorepos require scanning root lockfiles, workspace manifests, and SBOMs together—single-source scans miss vulnerabilities
• •Dependency hoisting installs shared packages at the root, making it critical to map which workspace owns and uses each dependency
• •Effective security strategy combines root-only scans for speed, per-workspace scans for accountability, and scheduled full scans for coverage
