SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Semgrep-based static analysis helps engineers detect security and quality issues directly in codebases without manual scanning.

Core Features & Use Cases

  • Automatic language detection and multi-language support for security scanning
  • Parallel scan execution across languages to speed up feedback
  • Merged SARIF output with clear results for audits and reviews
  • Use cases include vulnerability discovery, code-quality checks, and compliance validation

Quick Start

Run a Semgrep scan on your codebase with automatic language detection and parallel execution.

FAQPage Schema
How do I run Semgrep static analysis on a multi-language repository?

Parallel Semgrep scans accelerate vulnerability discovery in multi-language codebases by automatically detecting languages and executing scanners simultaneously, merging SARIF outputs into a single results file for streamlined audits.

Can I get merged SARIF output from parallel Semgrep security scans?

Yes, you can get merged SARIF output by running parallel Semgrep scans across detected languages, which consolidates all security and code-quality findings into a single results file for easy review and compliance validation.

Does this Semgrep scan require explicit approval before execution?

Yes, the Semgrep scan enforces a hard gate for plan approval before execution, ensuring that users explicitly authorize the security analysis and chosen third-party rulesets before any codebase scanning begins.

What is the best way to perform taint analysis across multiple programming languages?

Performing taint analysis across multiple programming languages is achieved by automatically detecting repository languages and applying Semgrep's third-party rulesets in parallel, identifying potential vulnerabilities and code-quality issues without manual scanning.

How does automatic language detection work for static security scans?

Automatic language detection for static security scans works by identifying the programming languages in a codebase and automatically choosing the appropriate parallel Semgrep scanners, enabling multi-language support without manual configuration.
