Run a real-world package intake simulation
Every click represents exactly one package request. Session counters update one request at a time, so the demo behaves like a real control plane instead of showing unrelated historical totals.
Explainable decision trace
Follow the request from developer context to the final delivery decision. The example code is deliberately harmless and only explains the historical technique.
Technique:
Reference: package information ↗
One governed path between npm and your builds
Developers and pipelines continue requesting dependencies normally, but package traffic is routed through NpmShield first. That creates a decision point while prevention is still possible.
Request
Developer or pipeline requests an npm dependency.
Authenticate
NpmShield ties the request to token, tenant and context.
Evaluate
Package intake is checked against the relevant policy.
Decide
Allow, review or block before external code reaches the build path.
Package intake as enterprise policy
NpmShield is positioned as a dependency firewall, not a replacement for vulnerability scanners: it controls the intake path before installation.
Block disallowed packages
Stop package requests that violate organization rules before they enter trusted environments.
Review uncertain requests
Use a review path when a request needs a human security decision.
Source & naming controls
Use the controlled gateway to govern package source and naming risks such as typosquatting or dependency confusion.
Dependency-chain governance
Control the dependency chain that comes with the top-level request.
Developer vs CI/CD policy
Separate tokens let organizations apply different rules to laptops and automated build jobs.
Ongoing intake decisions
Continue controlling packages when versions, maintainers or dependency relationships change.
Turn dependency intake into evidence
Package request, token, tenant, timestamp and decision can become measurable security evidence instead of assumptions.
zod@latestcrossenv@latestua-parser-js@0.7.29typescript@latestStart with visibility. Scale into enforcement.
The website explicitly positions a focused, visibility-first pilot as a practical rollout: route one team or pipeline first, understand real dependency behavior, then tighten review and blocking policies.
Observe
Measure package volume, token usage, install behavior and bypass paths.
Review
Introduce security review for uncertain requests without stopping normal engineering work.
Enforce
Block package intake that falls outside the approved security policy.
Expand
Add teams using scoped tokens and policies matched to each team or pipeline risk profile.
