What is Cloudflare?
Cloudflare protects and accelerates websites with a global edge network, DDoS protection and DNS.
What is Semgrep?
Semgrep is a fast, open-source-rooted static analysis tool that helps developers and security teams find bugs, security vulnerabilities and code-quality issues across their codebases — and enforce their own standards — without the slowness and noise that plague traditional SAST tools. Its name hints at its approach: "semantic grep," a way to search code for patterns based on its structure and meaning, not just text, making it both powerful and approachable for developers.
The key to Semgrep's popularity is that it's genuinely developer-friendly. Writing custom rules is intuitive — they look much like the code you're trying to match — so teams can codify their own best practices, catch specific anti-patterns, and prevent classes of bugs from recurring, all without becoming static-analysis experts. It ships with a large library of community and curated rules covering common security vulnerabilities across many languages and frameworks, so you get value immediately, and it runs fast enough to fit into local development and CI pipelines without grinding things to a halt.
For security teams, Semgrep provides a scalable way to embed security checks directly into the development workflow, catching issues early — when they're cheapest to fix — rather than late in a heavyweight audit. It can scan code, dependencies and secrets, integrate with CI/CD and code hosts, and give teams a clear, low-noise stream of actionable findings. This shift-left, developer-centric philosophy has made Semgrep a favorite among engineering and AppSec teams that want effective security and code governance without alienating developers with slow, false-positive-ridden tools. For organizations that want to find vulnerabilities, enforce standards and improve code quality in a way developers will actually adopt, Semgrep offers a fast, flexible and pragmatic solution that has earned its strong reputation in the security community.
