Software composition analysis (SCA) tools scan the open source libraries in your applications for known vulnerabilities and license risks. There is no official ranking, but these ten are among the tools security teams commonly shortlist, listed alphabetically.
| Tool | Model | Notable for |
|---|---|---|
| Black Duck | Commercial | Detailed component and license analysis |
| Checkmarx SCA | Commercial | Part of the Checkmarx application security platform |
| GitHub Dependabot | Included with GitHub | Alerts and automatic pull requests for vulnerable dependencies |
| GitLab Dependency Scanning | Included with GitLab | Runs inside GitLab CI pipelines |
| JFrog Xray | Commercial | Scans artifacts stored in JFrog Artifactory |
| Mend SCA | Commercial | Automated dependency updates, formerly WhiteSource |
| OWASP Dependency-Check | Open source | Free command-line and build plugin scanner |
| Snyk Open Source | Commercial with free tier | Developer-focused fix pull requests |
| Sonatype Lifecycle | Commercial | Policy enforcement across the software supply chain |
| Veracode SCA | Commercial | Part of the Veracode application security platform |
Whichever tool you choose, SCA produces a large volume of findings, and many flagged libraries are never actually called by your code. Seemplicity’s SCA Analysts check whether the vulnerable code is reachable before a finding is prioritized, which cuts the list down to the dependencies that pose real risk.
