Secured before it enters your stack – continuously until the end-of-life date.
All the ecosystem benefits. None of the blind trust.
SecureChain for Open Source Software
A safer JavaScript supply chain – verified at source, malware-screened, and secured as long as it remains in your stack
SecureChain replaces the public npm registry with a curated, rebuilt-from-source repository. It vets every package at install, patches vulnerabilities as they emerge, and keeps your dependencies secure long after maintainers stop.
Coverage across the ecosystems behind today’s production stacks
The npm Problem Is Bigger Than You Think
npm is the world's largest package registry.
It’s also the most exploited software supply chain in existence.
new malicious packages were identified across major open-source registries, with over 99% of them appearing on npm
One registry. Thousands of potential entry points.
-
The Shai-Hulud worm
A self-propagating malware campaign that spread through open-source ecosystems by hijacking trusted packages and silently infecting downstream environments.
-
Axios compromise
A supply chain attack where a widely used HTTP library dependency was targeted, exposing how even trusted packages can become vectors for malicious code.
These aren't edge cases. They're the normal operating environment for any team building on Node.js.
How risk enters your npm dependencies
Your exposure doesn’t come from one place. It comes from how npm works.
At install and every update thereafter
Every time your team runs npm install, they’re trusting a public registry.
That trust is frequently exploited.
- Typosquatted packages
- Hijacked maintainers
- Tampered artifacts
- Malicious install scripts
Everything that happens after the last update
Every time your team runs npm install, they’re trusting a public registry.
That trust is frequently exploited.
- Packages go stale
- Maintainers move on
- CVEs continue to surface
Your application keeps running the same code – but the risk keeps increasing.
Most npm security tooling is limited to one phase of exposure.
A scanner that checks at install. A SCA tool that flags known CVEs.
An advisory feed that tells you something is vulnerable but doesn't fix it.
SecureChain is different because it's not advisory – it's active.
And it doesn't stop when the maintainer does.

The Speed and Flexibility of Open Source,
Without the Risk.
With SecureChain, every package is:
Rebuilt and verified
Every package is rebuilt from source in hardened, isolated environments — no inherited binaries, no opaque upstream artifacts. What you install is what was built, verified end to end.
Malware-scanned
Every package is screened for known malware, suspicious code patterns, and supply chain risks. Anything that fails inspection is blocked before it reaches your environment.
Continuously patched
Active components are monitored and patched under SLA as CVEs emerge. When upstream maintenance ends, Endless Lifecycle Support (ELS) keeps delivering fixes for as long as you depend on the package.
Compliant and audit-ready
Know exactly what’s running and what’s been patched. SLSA Level 3 provenance, SBOM, and VEX deliver complete supply chain assurance — the evidence your auditors need on demand.
+ On-demand coverage
If a package you depend on isn’t in the catalog yet, we’ll add it
at no additional cost: verified, patched, and supported like every other.
Built for teams who own the risk:

Frequently Asked Questions
Yes. npm packages can run lifecycle scripts like preinstall, install, and postinstall automatically during npm install. Attackers abuse this through typosquatting, hijacked maintainer accounts, tampered artifacts, and campaigns like Shai-Hulud. SecureChain analyzes packages before delivery and blocks malicious scripts or suspicious behavior before they reach your environment.
By default, you don’t. The public npm registry distributes published tarballs without proving they match the upstream source or build process. Clean-looking source can still produce a risky installable artifact. SecureChain rebuilds packages from verified source in hardened environments and provides SLSA Level 3 provenance, so each package is traceable and auditable.
Very large. One top-level npm package can pull in hundreds of transitive dependencies. Most are never reviewed, but each can execute code and expand your attack surface. SecureChain secures the full npm dependency tree, not just the packages you chose directly.
Use a trusted package source, not just scanners. SecureChain verifies npm packages before install, blocks malicious behavior, and continuously patches CVEs under SLA. This gives production teams a controlled, auditable source of npm packages.
No. SecureChain monitors npm packages for newly disclosed CVEs and delivers validated fixes aligned with your pinned versions. That reduces manual tracking, npm audit follow-up, and urgent upgrade pressure.
Risk increases. Unmaintained npm packages can stay in production while new vulnerabilities continue to appear. SecureChain is complemented by Endless Lifecycle Support (ELS), which backports critical fixes so you can stay secure without forcing an upgrade or refactor. When a package SecureChain maintains reaches end-of-life, ELS continues security coverage with no action needed on your side.
No. SecureChain works as a drop-in replacement for the public npm registry. Developers keep using npm, Yarn, or pnpm with the same commands and workflows. It can also be configured as an upstream source for JFrog Artifactory, Sonatype Nexus, and GitHub Packages.
