Black Duck (part of Synopsys) is built for large-scale enterprise governance — binary and code-snippet-level open-source detection, a deep license-compliance knowledgebase, and multi-team policy rollouts. Real value if you're standing up an org-wide SCA program. But if you just want to check a project's dependencies right now, Black Duck means a sales call, an account, and an onboarding process before you see a single finding.
DepWarden is a free, anonymous alternative for that faster path. Paste a manifest, a lockfile, or an SBOM — or point it at a public repo — and get results in seconds, in a private, session-isolated workspace. No account, no sales call, and it never receives your source code or compiled binaries, only the dependency manifest text.
Every component is checked against the full OSV mirror, then enriched with CISA KEV (actively exploited) and FIRST EPSS (exploit probability) — so you get a short "fix these first" list instead of hundreds of undifferentiated CVSS scores.
To be fair: Black Duck can identify undeclared open source from binary artifacts and copy-pasted code snippets — real value no manifest-based scanner (this one included) can match — plus a mature license-compliance knowledgebase and audit trails built for large, multi-team organizations. If that's the job, Black Duck is built for it.
Typosquat and dependency-confusion detection, OpenSSF Scorecard health, deprecated and end-of-life packages, plus a full compliance round-trip — ingest an existing CycloneDX or SPDX SBOM, export a CycloneDX SBOM, an OpenVEX document, and a NOTICE / license-obligations file. No add-on module, no gated tier.
Connect a GitHub, GitLab, Bitbucket or Azure DevOps repo branch with a personal access token and attach a schedule — daily, weekly or monthly — and DepWarden re-scans it automatically and emails a report. No token retained beyond the scan.
Try it: paste a pom.xml or package-lock.json and see prioritized findings in seconds — no sign-up. Full feature-by-feature breakdown: DepWarden vs Black Duck.
