In this in-depth walkthrough, we will show you how to turn ggshield, the GitGuardian CLI, into a practical guardrail for keeping secrets out of your code and CI pipelines. You’ll see exactly how to install and authenticate ggshield, then use it to scan repositories, local paths, archives, Docker images, PyPI packages, and CI environments for hardcoded credentials. We’ll also walk through configuring Git hooks with ggshield install.
