Semgrep is an open-source static analysis engine that scans code for security vulnerabilities, bugs, and code quality issues using syntax-aware pattern matching rules. Unlike regex-based tools, Semgrep understands code structure, making it highly accurate with minimal false positives. Its AI assistant helps write and refine rules. Security engineers and AppSec teams use Semgrep to enforce secure coding standards, detect custom vulnerability patterns specific to their codebase, and run automated security reviews in CI pipelines. The rule-as-code approach lets teams version control their security policies. Semgrep's open-source core combined with its extensive rule registry (1,000+ community rules covering OWASP Top 10) makes it accessible to teams without dedicated security budgets. The commercial Semgrep Code product adds AI-assisted triage and remediation features.
