SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Semgrep enables fast, accessible static analysis to detect security issues, pattern mismatches, and code quality problems across codebases.

Core Features & Use Cases

  • Quick scans with auto-detected rules and taint-mode analysis for precise, safe data flow tracking.
  • Custom rules and CI/CD integration to enforce security and coding standards in pipelines.
  • Use Case: Scan a repository for OWASP Top 10 patterns or project-specific vulnerabilities in seconds.

Quick Start

Install Semgrep and run a quick scan on your codebase to identify vulnerabilities.

FAQPage Schema
How do I run static analysis to detect security vulnerabilities in my codebase?

Static analysis with Semgrep scans individual files or entire repositories to detect security vulnerabilities and code quality issues. You can run quick scans using auto-detected rules or custom configurations to identify OWASP Top 10 patterns in seconds.

What is taint-mode analysis and when do I need it for security scanning?

Taint-mode analysis tracks data flow through your code to identify precise security vulnerabilities. You need taint-mode usage when hunting for complex vulnerabilities that require understanding how untrusted data moves through JavaScript, Python, or Go applications.

Can I enforce custom security rules in my CI/CD pipeline?

You can enforce custom security rules in CI/CD pipelines by integrating Semgrep with a config.yml file or using --config rules. This allows you to enforce coding standards and security policies automatically during code reviews and pipeline execution.

Do I need to install anything specific to scan code with Semgrep?

You need to install Semgrep via pip install semgrep or use Docker. No other dependencies are required. Once installed, you can immediately scan codebases across JavaScript, Python, Go, and other supported languages.

What's the best way to scan a repository for project-specific vulnerabilities?

The best way to scan for project-specific vulnerabilities is using Semgrep with custom rules defined in a config.yml file. This static analysis approach detects pattern mismatches and security issues tailored to your codebase in seconds.
