Choose open source if you have engineers who will own the pipeline, data feeds, and triage workflow. Choose commercial if you need support, reporting, policy across many teams, and time back. Most mature teams end up mixing the two. The real cost of either is people time, not the license.
What open source gives you
- No license fee and the ability to read the code
- Flexibility to wire it into your own workflow
- Community fixes for common ecosystems
What it asks of you: you run it, you update it, you build the reporting, and you decide how findings are stored, assigned, and closed.
What commercial gives you
- Support when a scan breaks or a result looks wrong
- A shared place for findings across teams
- Policy, exceptions, and audit trails
- Extra analysis such as reachability and prioritization
- Reporting for customers and auditors
What it asks of you: a budget, a security review of the vendor, and a check that the extras are real.
Compare on total effort
Add up what each route costs over a year.
- Setup time and pipeline integration
- Maintenance: updating the tool and its data
- Triage time, which depends on noise
- Reporting effort for audits and customers
- Training and onboarding for new teams
A free tool that creates ten hours a week of triage is not free.
When open source is enough
- One or two repositories, a few engineers
- You want a baseline now and can accept manual reporting
- A strong platform team that likes owning tools
When commercial usually wins
- Dozens of repositories and several teams
- Customers or auditors ask for evidence you must produce on demand
- You want policy enforced uniformly
- You lack time to build and maintain the glue
A mixed approach
Many teams run an open source scanner in developer workflows and a commercial platform for aggregation, policy, and reporting. If you try this, make sure both feed the same inventory so findings do not duplicate.
Test before deciding
Run both on the same repository and compare using the method in how to measure SCA false positives during a pilot. Let the numbers settle the argument.
Safeguard is a commercial platform with SBOM and dependency scanning, and a free scan at https://gold.safeguard.sh/scan lets you compare it against whatever you run today.
Questions to settle before choosing
Who will own the tool when the person who set it up leaves? How will findings reach the team that can fix them? What will you show an auditor or customer, and who will produce it? If the answers point to people you do not have, factor that into the cost. If they point to capabilities you already have, open source may serve you well for years. Be honest about the staffing assumptions, since that is where most of the real cost hides.
Quick check
Is open source SCA less accurate?
Not by definition. Accuracy depends on data and matching quality. Measure it on your own code.
