Semgrep: Open-Source Bug & Security Vulnerability Detector
Semgrep detects bugs and security vulnerabilities in source code using pattern matching, scanning codebases for predefined patterns corresponding to vulnerabilities or errors
What is Semgrep?
Semgrep is an open-source tool developed by r2c for finding bugs and security vulnerabilities in source code. It works by using pattern matching to scan codebases and match code snippets against a set of predefined patterns that correspond to known vulnerabilities, bugs, and anti-patterns.
Some key features and capabilities of Semgrep include:
- Detection of security issues like SQL injections, cross-site scripting, hardcoded credentials, insecureTLS protocols, and more
- Finding bugs like null pointer dereferences, resource leaks, race conditions
- Enforcing best practices and coding standards
- Integration with CI/CD pipelines for rapid feedback
- Support for over 25 programming languages including Java, Python, JavaScript, Go, Ruby, C, PHP, and more
- Easy semantic pattern writing using Semgrep's custom rules language
- Open source GPL license and available as SaaS or self-hosted options
Overall, Semgrep brings the power of grep to source code analysis and security. Its flexibility via custom rules and broad language support make it useful for developers and AppSec engineers looking to scale code audits and security best practices across their codebase.
