Deepsec

Deepsec is an open source security review tool that uses coding agents to find vulnerabilities across a repository.

Deepsec is an open source security review tool designed to find vulnerabilities across an entire repository. It uses coding agents and a scaled virtual machine fanout to review all existing code rather than limiting checks to pull requests. The system revalidates every finding before it reaches a development team. It runs in your own infrastructure and supports strong agent sandboxing. It is built for development and security teams needing comprehensive repository analysis.
