Semgrep
Developer-first code security tool with customizable rules and AI-assisted fix suggestions for SAST and secrets scanning.
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.
Why AI-ENHANCED
Semgrep is an established code security platform that has integrated AI fix generation and AI-assisted rule writing into a mature static analysis product known for its developer-friendly, customizable approach.
Best for
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.
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.
Limitations
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.
Semgrep is a SAST and SCA tool — organizations needing dynamic analysis (testing running applications) must use Veracode or Snyk DAST alongside it.
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.
Alternatives by segment
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.
