Semgrep

Semgrep is a fast, lightweight static analysis tool that lets developers write custom rules to find bugs, enforce code standards, and detect security vulnerabilities using a simple, code-like pattern-matching syntax. Unlike traditional static analysis tools that require complex configuration, Semgrep rules read like the code they are searching for, making them accessible to developers without specialized security tooling expertise. Its extensive community rule registry covers OWASP Top 10, common CVEs, and framework-specific security patterns across 30+ programming languages.

Enterprise teams use Semgrep to build custom security guardrails that scale across thousands of repositories without slowing down developer workflows. Semgrep's cloud platform (Semgrep App) provides centralized rule management, findings dashboards, and CI/CD integration across all repositories in an organization. Enterprise features include SSO, custom rule sharing across teams, cross-file and cross-function analysis (taint tracking), and integration with notification systems for real-time alerting on new findings.

Semgrep differentiates itself through the simplicity and expressiveness of its rule language, which enables security engineers and senior developers to codify organization-specific security patterns in minutes rather than days. While commercial SAST tools provide broad vulnerability detection, Semgrep excels at encoding institutional knowledge -- rules like "never use this deprecated authentication method" or "always validate this parameter before passing it to this internal API." This makes it particularly valuable as a complement to traditional SAST tools, adding a layer of organization-specific security enforcement that generic scanners cannot provide.
