Snyk

Snyk is a developer-first security platform that scans code, open-source dependencies, container images, and infrastructure-as-code for vulnerabilities. It integrates directly into the developer workflow — IDE, pull requests, CI/CD — and doesn't just flag issues but suggests or auto-generates fixes, including automated dependency-upgrade pull requests. Snyk maintains its own vulnerability database and is widely used for open-source dependency scanning (Snyk Open Source), container scanning (Snyk Container), and SAST (Snyk Code).
