Yellow JackYour software supply chain has an open door
Every npm install, pip install, anddocker pull reaches straight past your perimeter and runs third-party code on your developers' machines and in your builds. Your network firewall never sees it. Scanners flag problems after the fact — but nothing stops a bad package at the door.
A quarantine checkpoint for every package
- 01
Point your package manager at us
Your developers' npm — and soon PyPI and Docker — is configured to fetch through Yellow Jack. No agents, no certificates, no traffic interception. The client talks to us by choice.
- 02
We inspect every package at the moment it's pulled
Each package is checked against a transparent, deterministic policy before it ever reaches a developer or a build — its software build practices, not guesswork.
- 03
Allow or block — deterministically
Trusted packages stream straight through. Risky ones are stopped with a clear reason. Every dependency, including transitive ones, passes through the same gate.
Enforcement, not just advice
Scanning tools tell you what's wrong. Yellow Jack stops it from getting in. We sit at the pull boundary and enforce your policy in real time — complementing the tools your team already runs, with no registry to rip out and nothing to migrate.

Building in the open
Yellow Jack is in active development. We'll be sharing progress — and write-ups on real-world supply-chain attacks — on our blog soon.
