Semgrep

Fast open-source SAST with custom rules

Semgrep is an AppSec platform with a widely used open-source engine for readable code rules plus commercial SAST, supply-chain and secrets workflows. Current product positioning emphasizes AI-assisted detection, triage and remediation, CI/pull-request integration and managed governance for security teams.

About Semgrep

Semgrep helps teams find insecure code patterns, dependency risk and leaked secrets close to developer workflows. Its readable rule model remains the core advantage: AppSec and platform teams can encode policies that look like code, run them locally or in CI, and tune findings without treating static analysis as a black box.

Current Semgrep positioning is broader than an older static-analysis-only description. The product surface includes Semgrep Code for SAST, Semgrep Supply Chain for dependency risk, Semgrep Secrets, Guardian, AI-assisted triage and remediation, managed scanning and governance for teams that need platform-level AppSec workflows.

The open-source engine should be described with license nuance rather than old star-count or MIT shorthand. GitHub currently reports semgrep/semgrep with LGPL-2.1 metadata and more than fifteen thousand stars, while the commercial platform adds hosted workflows, support and enterprise controls. Buyers should test rule quality, CI performance and finding noise on their own repositories.

LLM vulnerability scanner and red teaming kit

Agentic Security is an open-source vulnerability scanner for LLM agent workflows that tests AI systems against jailbreaks, fuzzing, and multimodal attacks. It probes weaknesses across text, image, and audio inputs through multi-step jailbreak simulations, randomized stress testing, and reinforcement learning-powered adaptive attacks. The toolkit connects directly to LLM APIs for high-volume real-world attack scenarios, helping developers identify and patch safety gaps before deployment.

Open Source

Automated code review for any linter on CI

reviewdog is an open-source automated code review tool that integrates any linter or static analysis tool with GitHub, GitLab, Bitbucket, and Gitea pull requests. Parses output in errorformat, Checkstyle XML, SARIF, and JSON formats to post inline review comments on changed lines only. Works with GitHub Actions, Travis CI, CircleCI, GitLab CI, and Jenkins. Supports 40+ languages through universal linter adapter architecture.

Semgrep vs SonarQube: Policy-as-Code SAST or Unified Quality Platform?

Semgrep is the stronger default for developer-first AppSec teams that want fast custom rules, security automation close to pull requests, AI-assisted triage, and security policy as code. SonarQube is the better fit when one enterprise quality platform must standardize code quality, security gates, and governance across a large portfolio.

Semgrep vs SonarCloud — AST-Level Rule Authoring vs Hosted Quality Gate Breadth

Semgrep and SonarCloud both catch security and quality issues in source code, but they approach the problem from opposite ends. Semgrep is a rule-based static analysis engine built for security engineers who want AST-level pattern precision and a community rule registry to extend. SonarCloud is a hosted code quality platform that bundles Quality Gates, PR decoration, technical debt tracking, and broad language coverage into one workflow. Picking between them depends on whether your primary concern is AppSec rule precision or developer-facing quality feedback at organizational scale.
