Overview
Semgrep is an extensible, developer-friendly application security platform that scans source code to surface true, actionable security issues. It unifies static application security testing (SAST), software composition analysis (SCA), and secrets detection into a single high-signal platform, helping teams move off legacy AppSec tools like Checkmarx or Snyk.
Developers love Semgrep because it dramatically reduces false positives — AI learns your code context to prioritize reachable vulnerabilities, and reachability analysis cuts false positives in high/critical severity findings by up to 98%. The result is a smaller triage backlog, faster engineering velocity, and security that scales with modern AI-assisted development.
Key Features
- Semgrep Code (SAST): Multimodal AI detection combines static analysis and AI reasoning to uncover OWASP risks, business logic flaws, and IDORs that traditional scanners miss.
- Semgrep Supply Chain (SCA): Reachability analysis flags only the dependencies that are actually exploitable, reducing false positives by up to 98%.
- Semgrep Secrets: Semantic, entropy, and validation analysis detect hardcoded secrets and real credentials, blocking unsafe merges by default.
- Semgrep Guardian: Scans and fixes AI-generated code the moment it's written, securing AI-powered development at the source.
- Semgrep Workflows: Build and deploy security pipelines that combine static analysis with AI at scale across your organization.
Use Cases
- Engineering Teams: Catch, flag, and fix real vulnerabilities before they ship, keeping security from slowing down development.
- Security/Compliance Teams: Automate, manage, and enforce security policies across the org while triaging 80% fewer false positives.
- AI-Powered Development: Secure AI-generated code and MCP server workflows so AI builders move fast without breaking things.
