deepsec

Vercel tool that uses coding agents to find and revalidate vulnerabilities across a repository

Aboutvercel.com

deepsec uses coding agents to find vulnerabilities across an entire repository. It revalidates every finding before it reaches your team, to reduce false positives. A CLI command sets it up, and OpenSec uses it for donated open-source reviews.
