Open source heavy teams should use analyst research for commercial options and market framing, then add open tools and their own tests. Critics have argued that analyst methods give open source limited consideration, so absence of open options in a chart says little about their usefulness.
What the criticism says
The Wikipedia article on the Magic Quadrant records a criticism that analysts do not consider open source vendors sufficiently, based on a public exchange between a vendor executive and a Gartner research executive. It also records a view that analyst methods can reshape a market to fit the tools used to measure it. These are criticisms, not settled findings, and the article reports no Gartner response to them.
Whatever you think of them, the practical point stands. A report built around commercial vendors will not tell you what free tools can do.
Where open tools fit
You may combine commercial and open components. Public projects and standards can supply:
- SBOM formats. CycloneDX and SPDX are open standards, and both are widely supported.
- Project health signals. OpenSSF Scorecard runs 18 automated checks on open source projects, including branch protection, code review, pinned dependencies and signed releases, and returns a score out of 10 per check.
- Exploit data. CISA's Known Exploited Vulnerabilities catalog and FIRST's EPSS scores are free to use. EPSS data is available by CSV, API and a GitHub repository.
- Verification practices. OWASP's Software Component Verification Standard is an open lab project.
A mixed evaluation plan
- List capabilities you need and mark which ones open tools already cover.
- Mark the gaps, typically around scale, support, policy at scale, reporting and workflow.
- Use analyst research to survey commercial products for the gaps.
- Test commercial candidates against what you already run, with the same corpus.
- Measure the added value, not the total value. If a product only repeats what your open tools do, it needs a different justification.
Costs of open tooling that are easy to miss
Open tools shift work to your team. Plan for upkeep, integration and triage. Include that effort in comparisons honestly, in hours rather than dollars, so neither side gets a free pass.
Be fair in both directions
Apply the same scorecard to open and commercial options. Do not penalise open tools for lacking a report, and do not credit commercial tools for having one.
Health checks on dependencies
Scorecard results are about projects you depend on, not about the vendor you buy from. Use them to judge the packages in your dependency tree, and treat them as one signal among several.
Safeguard offers SBOM and dependency scanning with a free scan at gold.safeguard.sh/scan, which you can compare against your current open source setup.
Try it yourself
Open the demo and see how exploitability signals change which findings you would fix first, then compare that with what your current open tools show.

Quick check
Should open source tools be on the same scorecard?
Yes. Use identical criteria and weights so the comparison is fair.
Is a Scorecard result a vendor rating?
No. It assesses open source projects, not commercial vendors.
