A small team needs software composition analysis (SCA) as soon as it ships software that uses open source packages to real users or customers. That is almost every team. If you cannot list your packages and their versions today, you are already past the point of starting.
TL;DR
- If you ship an app with open source packages, you have the need, even with a team of two.
- Start small: one project, one scan, a short fix list.
- Six signs that it is time: customers ask, you cannot list your packages, you inherited code, you ship often, you handle sensitive data, or you have had a scare.
- You do not need a big program on day one.
- Add automation in steps: scan, then pull request checks, then scheduled rescans.
What does SCA do, and why would a small team care?
Definition: Software composition analysis (SCA) lists the open source packages inside your software and checks them against databases of known vulnerabilities, so you find out about problems in code you did not write.
Small teams lean on open source more than large ones do. It is how two people can build what used to take twenty. That is a good trade. The cost is that you now depend on the care of hundreds of strangers, often without knowing their names. For how the numbers add up, see why your app has hundreds of dependencies.
Think of a food truck. It might have only two staff, but its menu depends on a dozen suppliers. If one supplier has a contamination problem, the truck needs to find out quickly and know which dishes are affected. SCA is that supplier watch for software.
The OWASP Top 10 says you are likely vulnerable if you do not know the versions of all components you use, including nested dependencies, and if you do not scan for vulnerabilities regularly. Nothing in that wording depends on company size.
What are the signs it is time to start?
Look at this table. If any row sounds like you, begin now.
| Sign | What it looks like | Why it points to SCA |
|---|---|---|
| Customers ask | Questionnaires ask how you manage open source risk | You need an honest, factual answer |
| You cannot list your packages | Nobody can say what versions are in production | You cannot protect what you cannot see |
| You inherited code | You took over a project, or acquired one | Old projects hide old packages |
| You ship often | Deploys several times a week | Each deploy can add or change packages |
| You handle sensitive data | Payments, health, or personal records | A flaw has a larger cost |
| You had a scare | A news story made you wonder if you were affected | You could not answer quickly |
The last sign is the most common. A big flaw hits the news, someone asks "are we affected?", and no one can answer. SCA, with an inventory, makes that question take minutes. Our guide on finding every app that uses a vulnerable library shows the difference.
What can wait until you are bigger?
You do not need all of these on day one. Here is what to do now and what can follow.
| Practice | Start now? | Notes |
|---|---|---|
| One scan of your main project | Yes | Takes under an hour |
| A short fix list for critical and high findings | Yes | Do the easy ones first |
| An owner for the results | Yes | Even if it is the same person who wrote the code |
| Pull request checks | Soon | Stops new problems from arriving |
| Scheduled rescans | Soon | New flaws appear after you ship |
| Ranking by reachability | When the list gets long | Cuts noise |
| Formal policies and approval flows | When you grow | Scale with the team |
| Detailed reporting for executives | When someone asks | Keep it simple until then |
The point is to avoid two mistakes. One is doing nothing because the full program sounds heavy. The other is buying or building a heavy program before you have fixed a single thing.
How should a small team start? A numbered plan
- Pick the project that matters most. The one customers use.
- Run a first scan. Follow the first scan guide.
- Fix the cheap wins. Patch and minor upgrades for critical and high findings.
- Name an owner. One person, with a standing slot in the week.
- Set a threshold for new code. For example, do not merge a change that introduces a new critical finding.
- Schedule a rescan. Weekly is a good start for an active project.
- Write a one paragraph policy. What you scan, how often, and who fixes. Short is fine.
- Review in a month. Add the next project, or tighten a rule.
A worked example with invented numbers
The figures here are invented to show a realistic start.
A team of four ships a mobile app backend and a web dashboard. A customer's security questionnaire asks, "How do you manage vulnerabilities in third party components?" The team has no process.
- Week 1: they scan the backend. 38 findings. 6 critical or high with a fixed version. They fix those 6 in two small pull requests, about 3 hours of work.
- Week 2: they scan the dashboard. 22 findings. 4 critical or high with a fix. About 2 hours of work.
- Week 3: they add a check on pull requests and a weekly scan. About 1 hour of setup.
- Week 4: they write a half page policy and answer the questionnaire truthfully: scanning is in place, a named owner reviews findings weekly, critical and high issues with a fix are handled first.
Total: under 10 hours across a month. They moved from "no process" to "a real, if simple, process." Note that they did not claim any certification or complete program. They described what they actually do. That honesty is what questionnaires reward.
What do small teams often get wrong?
- Waiting for the "right" tool. Start with what you have. The OWASP guidance names OWASP Dependency Check among its example tools for inventorying components, and package managers offer built in checks. For example, the npm documentation describes an audit command that reports known vulnerabilities in your dependencies.
- Chasing zero findings. You will not reach zero. Aim for a short, ranked list with owners.
- Fixing in giant batches. Small batches are easier to test.
- Scanning once. The OWASP guidance says organizations need an ongoing plan for monitoring, triaging, and applying updates for the lifetime of the application.
- Treating the scan as a promise of safety. It is a snapshot of known flaws. See what is a known vulnerability.
Do I need to hand over my source code to start?
Often not. SCA mainly reads dependency files rather than your business logic. Some teams prefer to keep everything inside their own network. A scanner that runs on your own machine and sends back only results can be a good fit in that case. The demo below shows one way that works.
Try it yourself
The demo below shows scanning on your own machines in a sample workspace. Click through and look for how scan jobs are picked up locally and how only the results, not the source code, go back to the workspace.

Quick check
Is SCA only for big companies?
No. Any team that ships software built on open source packages has the need, and small teams often rely on open source more heavily than large ones do.
How much time does it take to start?
A first scan of one project and a first batch of fixes usually fits in a few hours. A weekly routine afterward can be short.
Do I need a policy before I scan?
No. Scan first and write a short policy afterward, based on what you actually do. A half page is enough to start.
What if I have no security person?
Name one developer as the owner of the results, give them a regular time slot, and keep the fix list short. Ownership matters more than job title.
How can Safeguard help with this?
You can start with the free scan at gold.safeguard.sh/scan. Safeguard's SBOM and dependency scanning builds the inventory, and reachability analysis helps a small team focus on findings its code can actually reach. Policies and gates can check pull requests, and compliance and evidence automation can help you answer customer questions with records instead of memory.
The Safeguard CLI, version 1.4.0, installs with a curl command on macOS and Linux or a PowerShell installer on Windows. Its install page is at safeguard.sh/download. The CLI can also write code, for instance to draft a dependency upgrade that you review before it goes in. Autonomous remediation is off by default, and every category starts on Manual.
