What is Snyk?
Snyk is a developer-first security platform that helps teams find and fix vulnerabilities in their code, open-source dependencies, containers, and infrastructure as they build. Modern applications are assembled from vast amounts of open-source code and run in complex environments, any part of which can contain security vulnerabilities. Traditional security testing happened late and was disconnected from developers, making fixes slow and painful. Snyk takes a different approach, embedding security directly into the developer workflow so issues are caught and fixed early, when it's easiest and cheapest to do so.
The platform scans the open-source dependencies your application relies on for known vulnerabilities, analyses your own code for security flaws, checks container images and infrastructure configurations, and crucially provides actionable guidance on how to fix what it finds — including suggesting the right version to upgrade to or generating fixes. It integrates into the tools developers already use, from their code editor and repositories to their CI/CD pipelines, so security checks happen automatically as part of building software rather than as a separate, after-the-fact gate. This developer-first, integrated approach makes security a natural part of development rather than an obstacle.
Snyk is used by development and security teams that want to build secure software without slowing down, embracing the practice often called DevSecOps. The value is security shifted left: by catching and helping fix vulnerabilities early in the development process, it dramatically reduces the risk and cost of security issues compared with finding them after release. Because so much of modern software is built on open-source components that can carry vulnerabilities, automated scanning of dependencies is especially important. For teams that want to ship secure software while maintaining their pace, Snyk provides the developer-friendly tools to find and fix security issues continuously, making security an integrated, manageable part of building software rather than a painful obstacle.
