Multiple layers of security controls protect you from the next malware attack

Malicious behavior scanning

Every package passes through malware and greyware scanning before it’s available in our endpoint for consumption.

Configurable cooldowns

Incorporate a cooldown period of your choosing directly into your JavaScript endpoint to act as a second layer of defense.

Built from source

Popular packages are rebuilt from source to provide another layer of malware protection for hackers’ highest value targets.

Step off the CVE remediation treadmill with Chainguard-patched artifacts

Access backported upstream fixes for critical and high CVEs, allowing you to remain secure on your current, stable version while you plan an upgrade.

All artifacts are tested to ensure the CVE is fixed while still passing functional tests
Every remediated artifact ships with signed SLSA L3 provenance and SBOMs
Auditors can run cosign verify to prove artifact integrity

Built for high-velocity engineering teams that can’t afford security drag

B2B SaaS

Pass enterprise vendor security reviews on day one. Prove your Node.js and frontend stacks are free of vulnerable npm dependencies and malware.

High-volume e-commerce

End the ‘patch or break’ dilemma during peak seasons. We secure your JavaScript supply chain against malicious packages and hard-to-fix CVEs.

Fintech and digital banking

Audit-ready by default. Signed SBOMs and provenance prove remediated artifact integrity and simplify compliance evidence reporting.

Covers all of your JavaScript dependencies

Access the web development stack that you need, such as TypeScript, Node.js, and React, along with every other project you required to build your application.

Works with your existing tooling

Chainguard Libraries works with your existing artifact managers and workflows. Each package has the same functionality as to what you’ll find on npm, so there are no breaking changes. Your engineers won’t notice a difference.

Signed, sealed, and dependable

Every Chainguard-built version comes with signed provenance and SBOMs, giving you indisputable proof that your dependencies came from the SLSA L3-compliant Chainguard Factory, not a vulnerable maintainer’s machine.

Govern artifacts based on your compliance standards

Use Chainguard Repository configure policies such as cooldowns, CVE blocking, license restrictions, and more, ensuring every pull abides by your org’s unique guidelines.
