About Semgrep

Semgrep is the leader in code security for builders. Teams catch, flag, and fix real issues before they ship, powered by security that learns as you build. Built for builders and trusted by security, the platform unifies SAST, SCA, and secrets scanning, embedding protection directly into the development workflow so security begins where code is written and lives where developers work. Semgrep combines deterministic static analysis with AI reasoning to power detection, triage, and remediation. This approach helps teams uncover real vulnerabilities, prioritize reachable risks, and fix issues faster. Customers report up to 80% fewer false positives across Code and Supply Chain, with 95% of findings validated by security reviewers across more than 6 million results. Founded in San Francisco, Semgrep is backed by Menlo Ventures, Felicis Ventures, Lightspeed Venture Partners, Redpoint Ventures, and Sequoia Capital. It is recognized by Gartner in Application Security Testing and trusted by leading organizations, including Snowflake, Dropbox, and Figma. Learn more at semgrep.dev.
