Often yes. Include an open source option as a baseline or as a candidate, then compare it on the work your team must do, support, coverage and exit, not only on license cost. It sharpens requirements and shows what a paid product must add to be worth buying.
Why include one
An open source candidate gives you a fixed point of comparison. If a commercial vendor cannot beat it on something you care about, you have learned what you are paying for. If it can, you have a clear reason for the spend.
It also tests your requirements. Teams often discover that two of their musts were really preferences.
What to compare
| Dimension | Questions to ask |
|---|---|
| Coverage | Which ecosystems, languages and file types does it actually support? |
| Data quality | Where does its advisory data come from, and how fast does it update? |
| Operations | Who runs it, upgrades it, and tunes it? How many hours per month? |
| Integration | Does it report into pull requests, tickets and dashboards without custom code? |
| Support | Who do we call at two in the morning, and under what terms? |
| Reporting | Can it produce audit evidence and a bill of materials in the formats we need? |
| Maintenance | Is the project actively maintained, with a clear release history? |
| Exit | Can we move findings and history out, or in? |
For the maintenance row, public project health signals such as release cadence, the number of active maintainers and how fast security issues get fixed are good evidence. Check them directly on the project page.
Where open source tends to fit well
- A small team with engineering time and a narrow need.
- A first step before a larger program, to learn what you actually need.
- A specific job, such as generating an inventory in a build step, alongside another tool.
- Teams that need to inspect or modify the code.
Where commercial products tend to fit well
- Teams that want a managed service and support terms.
- Needs that require reporting, workflow and audit features beyond what a single command line tool offers.
- Large estates where central policy and ownership matter.
Neither list is a rule. Run the same test on both.
How to run a fair comparison
- Use the same repos and the same success criteria for both.
- Count the hours your team spends running and tuning each.
- Score support and continuity honestly. A tool that depends on a single volunteer is a risk.
- Decide in advance what would make you pick each one.
A hybrid is allowed
Many teams run an open source scanner in builds and a commercial platform for prioritization, policy and evidence. If you try this, test that the two do not double-report the same issue in different words.
A worked example: a two week bake-off with a baseline
A team of ten engineers wants to scan dependencies. They include one open source command line tool and two commercial options, and run the same plan.
| Task | Open source baseline | Commercial option 1 | Commercial option 2 |
|---|---|---|---|
| Install and first scan | Command line, a short script | Hosted onboarding | Hosted onboarding |
| Pull request reporting | Needs a CI step the team writes | Built in | Built in |
| Findings in a shared view | Needs a separate dashboard or exported file | Built in | Built in |
| Policy and exceptions | Config files in the repository | Interface with an approval record | Interface with an approval record |
| Inventory export | Yes, open formats | Yes | Partial |
| Audit evidence | The team assembles it | Reports available | Reports available |
| Hours to run per month | Recorded in the trial | Recorded in the trial | Recorded in the trial |
The open source tool may win on cost and transparency and lose on workflow and evidence. The right call depends on whether the team has the time to build the missing parts. The baseline makes that trade explicit instead of leaving it as a hunch.
Check project health before you adopt
For an open source candidate, collect a few public facts:
- When was the last release, and how often do releases happen?
- How many people maintain it, and who is the sponsor, if any?
- How quickly are reported security issues handled?
- Is there a published disclosure policy and a way to report a problem privately?
- What license applies, and does it fit your use?
- Is there documentation for installation, configuration and upgrades?
These facts are all visible on the project's public pages. Write them in your scorecard like any other evidence.
Licensing and internal use
Check the license for any condition that matters to you, such as obligations when you modify the code or offer it as a service. This is a topic for your legal team; this post is not legal advice.
Support model comparison
| Need | Open source | Commercial |
|---|---|---|
| Urgent help | Community channels, your own engineers | Contracted support terms |
| Roadmap influence | Contribute, sponsor | Feature requests, account relationship |
| Upgrades | You schedule and test | Vendor schedules, often hosted |
| Continuity risk | Project may slow or stop | Vendor may change or be acquired |
Both models carry continuity risk, in different forms. Write an exit plan for either.
Decide with a written rule
Before the trial, write what would make you choose each. For example: "We choose open source if it meets all musts and takes under a set number of hours per month. We choose commercial if it removes a must-have gap or cuts triage effort by a margin we agree in advance." Then follow the rule.
Where Safeguard fits
If you want a commercial candidate alongside an open source baseline, Safeguard's GA capabilities include dependency scanning, SBOMs, reachability analysis, and policies and gates. The free scan at https://gold.safeguard.sh/scan lets you compare its output against an open source tool on the same repo.
Try it yourself
Click through it at your own pace, or open it full screen. Look at the inventory a dependency scanner builds, then compare it with what an open source baseline gives you on the same repo.
Quick check
Does open source mean no vendor risk?
No. You trade vendor risk for maintainer and operational risk. Assess both.
Should an open source tool go through the same RFP?
A lighter version, yes. Answer the same requirements from documentation and your own testing.
Does using open source tools remove the need for a security review?
No. You still review how the tool is configured, what access it has, and how it is updated. The review is of your deployment, not of a vendor contract.
