PROFILE

Tal Steiner

Developed and delivered an experimental software composition analysis (SCA) dependency path feature across the semgrep-interfaces and semgrep repositories, enabling the CLI to output transitive dependency chains for enhanced security analysis. The implementation introduced a new schema and computation logic using Python and TypeScript, with dependency paths surfaced in findings to align CLI output with the AppSec Platform. The approach ensured backward compatibility by making the feature opt-in via an experimental flag and regenerating relevant bindings. This work improved visibility into dependency origins, supported risk assessment, and laid the foundation for broader security provenance analytics and faster remediation across codebases.

June 2026: Delivered experimental SCA dependency path feature across semgrep-interfaces and semgrep, enabling the CLI to output transitive dependency chains and align with AppSec Platform. The work is backward-compatible and opt-in via an experimental flag, with bindings regenerated and a new dependency_path.py to compute paths from the dependency graph. No major bugs were reported; this feature set enhances security provenance, risk assessment, and remediation speed. Technologies demonstrated include Python, TypeScript, proto, JSON Schema, SARIF, and CLI tooling.
