Why binary analysis is structurally different
Source-code scanning tools — including most SCA platforms — analyze what developers declared was in their software. They read package manifests, lock files, and import statements. Binary analysis starts from the compiled artifact — the thing that actually runs. It doesn’t require source code access and doesn’t depend on vendor-supplied metadata. Every component present in the binary is identified directly, regardless of whether it appears in any SBOM, package manifest, or documentation. This distinction matters most for four categories of content that source-code tools structurally cannot reach:- Statically linked libraries compiled directly into an executable without leaving a package manifest entry
- Precompiled third-party components where source code was never available to the buyer
- Transitive dependencies pulled in by third-party components and compiled into the binary, invisible to tools that only resolve declared direct dependencies
- Backported patches where a vendor fixes a CVE without changing the version number, making version-based matching wrong in both directions
