2017Semgrep builds an open-source-powered application security platform spanning code, supply chain, secrets, and AI-code security.
Semgrep's open, extensible rule engine and large community registry give users broad coverage they can adapt to their own codebases. Its hybrid deterministic-plus-LLM detection produces findings that security researchers agree with at high rates.
Reachability analysis cuts false positives in software composition analysis, and Semgrep's agentic workflows find more true positives than frontier AI models alone at lower cost.

A late-2024 licensing change for Semgrep rules drew community criticism and prompted an Opengrep fork backed by rival vendors. Its AI-assisted features also depend on third-party frontier models.
The market includes entrenched incumbents such as Snyk, Checkmarx, and GitHub, which compete for the same developer-security budgets.

Security teams remain outnumbered by developers roughly 100 to 1, and the rise of AI-generated code is growing vulnerability volume faster than traditional review can absorb.
Security is shifting from CI gates toward in-agent guardrails, and Semgrep raised $100M in 2025 to scale autonomous application security for that transition.

Semgrep uses an open-core freemium model. The Free Edition supports teams of up to 10 contributors, while paid Teams plans start at $30 per contributor per month for Code and Supply Chain and $15 for Secrets.
Enterprise pricing is custom, adding options such as on-premises SCM deployment and expanded AI credits for larger security programs.

Semgrep's AppSec platform unifies static application security testing (Semgrep Code), software composition analysis (Supply Chain), secrets detection, Guardian for AI-written code, and agentic workflows for deep vulnerability hunting.
The platform supports more than 40 languages, runs over 75 million scans per year, and offers 3,000+ community rules. Customers include Snowflake, Dropbox, Figma, Lyft, and Notion.
