Semgrep
Semgrep is a static analysis security testing tool designed to identify vulnerabilities and logic errors by matching source code against declarative patterns. It functions as an automated scanner that integrates into development workflows to detect insecure code patterns and enforce coding standards before deployment.
The engine utilizes a language-agnostic intermediate representation and a modular parser architecture to normalize diverse programming languages into a unified format. This allows for consistent rule execution across different codebases, enabling users to perform custom structural searches and track the flow of untrusted data through an application.
Beyond security vulnerability detection, the tool supports automated code quality enforcement and supply chain security analysis. It optimizes performance through incremental scanning, which monitors file modifications to re-analyze only the segments that have changed. The platform also facilitates integration with external security systems and developer assistants by exposing analysis findings through standardized communication protocols.
Features
