The platform allows security engineers and developers to write custom code analysis rules in a readable pattern-matching syntax that mirrors the code being analyzed, making it far more approachable than legacy SAST tools. Semgrep supports over 30 programming languages and integrates into developer workflows through IDE plugins, pre-commit hooks, and CI/CD pipelines. The company offers Semgrep Code for SAST, Semgrep Supply Chain for dependency vulnerability scanning, and Semgrep Secrets for detecting hardcoded credentials. Semgrep has been widely adopted at major technology companies for internal security rule development and is used by security teams to enforce coding standards at scale. The combination of open-source community adoption and an enterprise SaaS offering has made Semgrep a leading platform-of-record for developer-first application security. ## Frequently Asked Questions ### What is Semgrep? Semgrep is an open-source static analysis platform that finds security vulnerabilities and code quality issues across 30+ programming languages using a human-readable pattern-matching syntax. ### How does Semgrep differ from traditional SAST tools? Semgrep uses a readable rule syntax that mirrors the code being analyzed, making it far easier for developers and security engineers to write, understand, and maintain custom security rules compared to legacy SAST tools. ### What products does Semgrep offer? Semgrep offers Semgrep Code for static analysis, Semgrep Supply Chain for open-source dependency scanning, and Semgrep Secrets for detecting hardcoded credentials and API keys in codebases. ### How much has Semgrep raised? Semgrep raised approximately $53M in Series C funding from Felicis Ventures, Sequoia Capital, and Redpoint Ventures. The company was founded by Isaac Evans and Domic Prout, Stanford researchers who originated the Semgrep technology, and has grown to serve thousands of enterprise security and engineering teams globally. ### What is Semgrep's open-source vs. commercial offering? Semgrep OSS (open-source) is MIT-licensed and freely available for running rules against codebases. The commercial platform adds Semgrep Code (managed cloud SAST with Semgrep-proprietary rules and AI-assisted triage), Semgrep Supply Chain (software composition analysis with reachability), and Semgrep Secrets (hardcoded credential detection with validity checking). Enterprise customers typically use the full Semgrep platform for comprehensive developer security tooling. ### How does Semgrep's taint analysis work? Semgrep's taint analysis tracks how potentially malicious data (user inputs, environment variables) flows through application code to sensitive sinks (database queries, shell commands, file operations). When user-controlled data reaches a dangerous function without proper sanitization, Semgrep reports a finding with a complete data flow path showing exactly how the taint propagates — enabling developers to understand and fix injection vulnerabilities with full context. ### Who competes with Semgrep in the SAST market? Semgrep competes with established SAST vendors including Checkmarx, Fortify, Veracode, and SonarQube, plus CodeQL (GitHub's query-based code analysis). Semgrep differentiates on rule writability (security engineers can write and share effective rules without language-specific compiler internals), scan speed (significantly faster than traditional AST-based SAST tools), and open-source model that enables a large community rule registry. ### How does Semgrep handle AI-generated code security? Semgrep's rules apply equally to AI-generated code since they analyze the output code patterns rather than how code was created. Semgrep has also developed AI assistant integration features that suggest fixes for detected vulnerabilities using LLMs, providing developers with specific remediation guidance alongside findings — accelerating the fix-forward cycle for AI-generated code that may introduce patterns developers are less familiar with. ## Tags open-source, cybersecurity, startup, b2b, saas, developer-tools, security --- *Data from geo.sig.ai Brand Intelligence Database.
