Top 10 SCA Tools for Open Source Dependency Security (2026)
Modern applications are 80–90% open-source code. Software Composition Analysis (SCA) tools scan your dependencies for known vulnerabilities, license compliance issues, and malicious packages. Here are the ten best SCA tools in 2026, compared by features, coverage, and pricing.
What Is SCA?
Software Composition Analysis (SCA) identifies all open-source components in your application, maps them to known vulnerability databases (NVD, OSV, GitHub Advisory), checks their licenses for compliance, and generates a Software Bill of Materials (SBOM) for supply chain transparency.
Why SCA Matters
of codebases contain at least one known open-source vulnerability
open-source downloads contains a known security vulnerability
increase in software supply chain attacks since 2019
