OWASP Dependency-Track vs SBOM Manager

OWASP Dependency-Track is a free, self-hosted platform for managing software-component risk across a supply chain. It builds inventories from software bills of materials and identifies vulnerable components, supporting CycloneDX SBOM, HBOM, VEX, and VDR documents for ingestion, analysis, and production. Components can be matched against NVD, GitHub Advisories, OSV, OSS Index, Snyk, Trivy, and VulnDB, while integrated EPSS support helps prioritize mitigation. Integrity checks flag components when published hashes differ from those served by an upstream registry. A Common Expression Language policy engine evaluates component rules and can break a build when a policy fails. Alerts can be filtered by event fields and sent to Slack, Teams, Mattermost, email, or webhooks. API and web interfaces are available, with least-privilege portfolio access and single sign-on through OpenID Connect, Active Directory, and LDAP. Version 5.1 uses separate API and frontend container images, supports Kubernetes, and requires PostgreSQL.

SBOM Manager is a free, MIT-licensed command-line tool for maintaining collections of Software Bills of Materials. It records components used in releases or builds and lets users check whether particular components and versions appear. Search tools include module lookup, project filtering, repository listings, and update-history views. Inputs can be SPDX 2.3 Tag/Value or JSON, CycloneDX 1.4 XML or JSON, CSV, and directory listings. Results can print to the console or go to a file in console or CSV formats. Repository archives can be exported and imported for restoration. The project describes continuous-integration and security-audit use. Vulnerability scanning requires a separately configured scanner that accepts an SPDX Tag/Value file; an example uses cve-bin-tool. The Linux tool requires Python 3.7 or later and installs with pip install sbom-manager. It cannot judge SBOM validity or completeness, or decide whether vulnerabilities require fixes.
