"Semgrep Supply Chain helped us be more productive by reducing the number of false positives."
Jessica Grider
Sr. DevSecOps Engineer, Policygenius
"Our engineers are excited we’ve got Semgrep Supply Chain. Managing vulnerabilities in NPM packages is chaos without any sense of reachability."
Rob Picard
Security Lead
"Nobody wants to be the security engineer who cried wolf, but doing the sophisticated analysis to find the real vulnerabilities takes lots of work. Use an expert tool like Semgrep Supply Chain to do it for you."
Roger Thornton
Former Founder & CTO of Fortify
“Semgrep Supply Chain has helped reduce the noise by 95%”

Semgrep Supply Chain is a software composition analysis (SCA) solution that uses codebase-aware reachability analysis to help teams prioritize the dependency vulnerabilities that matter most. It reduces noise, helps developers focus on real risk, and accelerates remediation with Autofix and AI-powered upgrade guidance.
A third-party evaluation by Doyensec compared Semgrep, Snyk, and Dependabot on their ability to identify which dependency vulnerabilities were actually reachable. Dependabot returned 97 false positives, Snyk returned 77, while Semgrep filtered all but two.
Semgrep provides visibility into the licenses used across your dependencies, lets you enforce license policies, block pull requests that violate your requirements, and search your codebase for any dependency and version.
Semgrep automatically scans dependencies against a continuously updated database of confirmed threats. It detects malicious open-source packages, hallucinated package names, and typosquatting attempts before they ever install in your environment.
Yes. Semgrep's Autofix feature generates fix PRs for dependency vulnerabilities automatically. It also performs line-level breaking change detection before creating the PR, so developers know exactly what will be affected by an upgrade before it happens.
