About Veln
Veln is a supply chain security company. We build tools that verify every npm and Python package install before it reaches a developer's machine.
We started with a simple observation: every major supply chain attack in the last five years succeeded because npm install and pip install trust the registry completely. No verification happens at the install moment — only after, when it's too late.
The Veln Agent intercepts npm, yarn, pnpm, pip, uv, and poetry traffic and runs a three-tier verification pipeline before any bytes reach the filesystem. The verification happens locally, adds less than 50ms for previously-seen packages, and requires no cloud connection to enforce.
We don't think security should be a checkbox. Most tools check CVE databases after you've already installed a compromised package. We intercept the install. Not the log. The install.
