What it does

Semgrep is a developer-first static analysis and code security platform that uses a pattern-matching approach to finding security vulnerabilities, bugs, and policy violations - with customizable rules that teams write to enforce their specific security standards. Its AI capabilities include AI-generated fix recommendations for detected vulnerabilities, AI-powered rule suggestions that help teams write custom detection rules, and semantic analysis that understands code semantics rather than just pattern matching. Semgrep's open-source core is free and widely adopted in security engineering teams - its commercial Semgrep Code, Supply Chain (SCA), and Secrets products extend the platform with managed rule sets and deeper analysis.

Strengths

  • Mid-market security engineering teams use Semgrep Code and Supply Chain for comprehensive SAST and dependency scanning - AI fixes reducing developer remediation effort and custom rules encoding organization-specific security requirements.
  • Large security teams use Semgrep at scale across hundreds of repositories - managed rule sets covering OWASP Top 10, secrets detection, and SCA providing defense-in-depth across the software supply chain.
  • Small engineering teams use Semgrep's free open-source tier for SAST in CI/CD - customizable rules enforcing team-specific security policies without the cost of enterprise AppSec tools.

Watch-outs

  • Rule writing requires security engineering expertise: Semgrep's customizability is a double-edged sword — teams that do not invest in custom rules get less tailored results than Semgrep's pattern-matching approach can deliver.
  • No DAST capability: Semgrep is a SAST and SCA tool — organizations needing dynamic analysis (testing running applications) must use Veracode or Snyk DAST alongside it.
  • Managed rule quality varies by language: Semgrep's managed rule sets are stronger for commonly analyzed languages (Python, JavaScript, Java) than for less common languages — teams using niche languages may find rule coverage insufficient.

Pricing

Semgrep OSS is free and open-source. Semgrep Code from $40/developer/month. Supply Chain and Secrets add-ons priced separately. Team plans with managed rules available. Enterprise pricing negotiated.
