Introducing deepsec: The security harness for finding vulnerabilities in your codebase
Today we’re open sourcing deepsec: a security harness powered by coding agents. It runs on your own infrastructure and surfaces hard-to-find issues in large codebases. You can run deepsec on your laptop without setting up a cloud service for privileged source code access. For inference, you can use your existing Claude or Codex subscription without any additional setup.

HTTP requests are inexpensive. Vercel charges ~$2/million, a fraction of a cent per call. But a single prompt to an agent on a frontier model can cost $2, making AI a million times more expensive, and inference theft one of the highest-margin businesses an attacker can run. We have seen this type of attack on our own APIs.
