Firmware Release Gate for sdkconfig and prj.conf

Finds the build-config lines that ship an ESP-IDF or Zephyr device with secure boot off, a debug port open, unsigned images or plaintext OTA.

Install

npx @readystack/firmware-release-gate file

Node 18+. The same 18 rules as the VS Code extension, from a terminal or CI.

Free

@readystack/firmware-release-gate --dir ./templates --report html --out report.html

An outside firmware-only security review starts around $6,000 and a full IoT device assessment runs $10,000 to $50,000; this is the config pass you run before you pay for one.
