Since 2017, GitGuardian’s detection engine has been scanning every single contribution and event on public GitHub–in repositories, gists, issues, and comments–catching every secret it can find.
We have built a database containing over %ntlss% million leaks, and it’s growing daily!
secrets detected in %stats-year%
growth in secrets leaked vs %previous-stats-year%
public commits scanned in %stats-year%

Taylor:
Hi, Owlie 👋 I’m a security engineer at HotDog Corp. Why should I search for my secrets across all available GitHub content? Why can’t I just scan the code repositories my organization owns?
Owlie:
Sure, Taylor! You should scan your own repositories for secrets, but it’s not enough. Secrets are susceptible to leaks during "out of office hours," often in places lying beyond your organization's perimeter or control.
Also, ‘vaulting’ your secrets is a good practice, but it does not guarantee they will never leak. If you truly want peace of mind, you should audit every secret in your pipeline for leaks.
Taylor:
How does this work? I wouldn't want to share secrets that might be safe out in the open and expose them to you or anyone else.
Owlie:
That’s a valid concern. No one sees or touches your secrets–not even GitGuardian!

This is a high-level overview. If you want to dive deeper into the technical details of the data flows, encryption, and more, read “HasMySecretLeaked – Building a Trustless and Secure Protocol".
Taylor:
Thank you for sharing all these details, Owlie! I just tried it and found my secret was safe 😌How can I audit all my secrets in one go now?
Owlie:
Great news! You should use ggshield, the GitGuardian command-line interface (CLI), to check all your secrets simultaneously. It has a few commands to prepare and check every secret you own for leaks. You can also connect it to your AWS Secrets Manager or HashiCorp Vault and pull your secrets. Keep scrolling, and I will show you what it looks like in your terminal!

Connect ggshield (GitGuardian CLI) with AWS Secrets Manager or HashiCorp Vault, collect all your secrets, and run a leak check in one command! Stay tuned for more integrations!
HasMySecretLeaked is a project from GitGuardian that aims to help individual users and organizations verify if their developer secrets have leaked on public repositories, gists, and issues on GitHub projects.
Users can interact with HasMySecretLeaked via the search bar on this webpage or the GitGuardian CLI ggshield. It is also integrated into the GitGuardian Platform in the Secrets Detection module.
HasMySecretLeaked comprises two components: a REST API used to interact with the service and a database containing all secret leaks discovered by GitGuardian on public GitHub. Both the source code of the REST API and the content of the database are closed-source and proprietary. Please note that all the secrets are hashed, and their corresponding locations are encrypted.
HasMySecretLeaked is also integrated into ggshield, the GitGuardian command-line interface application. The CLI is open-source, and its source code is available on the official GitHub repository.
ggshield is a command-line interface application developed by GitGuardian. ggshield helps developers detect and prevent hardcoded secrets (like API keys, certificates, and database connection URLs) before pushing their code to shared repositories. ggshield acts as a wrapper for GitGuardian’s Python API client, py-gitguardian.
The minimum requirements for installing ggshield are:
Note: GitGuardian only supports versions of ggshield above and including v1.12.0. The package runs on MacOS, Linux, and Windows.
For more information, please read the official documentation.
HasMySecretLeaked is available for free. Visitors to this web page are given 5 credits daily when using HasMySecretLeaked via the search bar.
Unauthenticated users of the GitGuardian CLI, ggshield, are given 5 credits daily. To get a larger quota, please sign up for a free GitGuardian account. GitGuardian authenticated users are given:
NB. If you have already installed ggshield, run ‘ggshield auth login’ and follow the web-based authentication flow, where you will be asked to log in to an existing account or sign up for a new one.
Widely adopted by developer communities, GitGuardian and ggshield are used by over %nggsu% thousand developers and rank 1st in the security category on GitHub Marketplace. Developers from leading companies, including Instacart, Orange, Iress, Beyond Identity, and NOW: Pensions, use ggshield for secrets scanning.
If you have found a bug or have suggestions for the GitGuardian team to improve ggshield, please visit the official GitHub repository to create an issue.
GitGuardian leads the way in Non-Human Identity security, offering end-to-end solutions from secrets detection in code, productivity tools and environments to strong remediation, observability and proactive prevention of leaks.
