Top 10 Software Composition Analysis (SCA) tools in 2025

Top 10 SCA tools for 2025

85% of the code that we use doesn’t come from our own code, it comes from our open-source components and dependencies. This means attackers can know your code better than you do! SCA tools are our best line of defense to keep our open-source supply chain secure.

Software Composition Analysis (SCA) tools, also known as open-source dependency scanning, help us understand the risks we have in our open-source supply chain. From known vulnerabilities, risky licenses or malware hidden in innocent-looking libraries.

Understanding the composition of your open-source supply chain can be very difficult and SCA tools have become an integral part of the application's security programs. However, they often are riddled with false positives and unnecessary noise so we wanted to break down precisely what to look for in a good SCA tool and review 10 of the market leaders in SCA right now.

How does Software Composition Analysis Work?

SCA tools provide an ongoing process for detecting vulnerabilities usually by checking our dependencies and versions against known vulnerabilities. Leaders in SCA however will go further and detect packages using high-risk licenses, conduct malware inspection, and even detect when packages are no longer actively maintained. In addition the approach tools take can differ, typically we see 6 different stages within a SCA tool.

1. OSS Dependency Scanning

• Scans application codebases, build directories, CI/CD pipelines, and package manager files to identify open-source (OS) dependencies.
• Detects both direct dependencies (explicitly declared) and transitive dependencies (inherited).

2. Generating a Software Bill of Materials (SBOM)

• Creates an inventory of all OS components with:
  • Component names, versions, locations, suppliers/maintainers
  • Associated open-source licenses.
• Often visualizes dependency relationships for better analysis and identifying potential vulnerabilities/conflicts.

3. Vulnerability Assessment

• Compares the SBOM against databases like NVD, CVE, GitHub Advisory, etc.
• Scanning open-source components for malware not declared in databases
• Uses Common Platform Enumeration (CPE) to map components to known vulnerabilities.
• Regularly updated databases ensure new vulnerabilities are flagged, even for older dependencies.

4. OSS License Compliance

• Identifies licensing terms for each dependency.
  • Examples: GPL (restrictive, requires sharing modifications) vs. MIT (permissive).
• Flags license conflicts or violations of internal organizational policies.

5. Vulnerability Remediation and Auto-Triaging

• Provides actionable recommendations
  • Suggests updates to patched versions (often automatically creating Pull Requests)
  • Links to security advisories.
  • Offers temporary workarounds.
• Prioritizes vulnerabilities based on severity, exploitability, and runtime impact (auto-triaging).

6. Continuous Monitoring and Reporting

• Periodically rescans the codebase for emerging vulnerabilities and updates SBOMs.
• Maintains real-time visibility into OS components, their versions, and associated risks.

Choosing The Right OSS Dependency Scanner

Choosing the right SCA tool is going to depend on the specific needs of your project and the technology it uses. It is important to note that SCA is only one part of a comprehensive application security plan and using a stand-alone SCA tool will mean needing to integrate with multiple different vendors.
