ggshield vs Talisman

ggshield is GitGuardian’s command-line tool for finding hardcoded secrets before code is pushed. It can scan local files and repositories, run before commits or in CI pipelines, and act as a pre-receive hook for self-managed version control. It also scans Docker image layers, build arguments, and Dockerfiles. GitGuardian’s documentation describes detection for more than 600 secret types. The open-source CLI uses a closed-source secrets detection library behind GitGuardian’s public API. It runs on macOS, Linux, and Windows, with API and self-hosted options. Standard installation needs Git and a supported, non-end-of-life Python version; standalone packages are an exception. Scans require an API key for a GitGuardian workspace, and the login command can provision and store a personal access token. Files over 1 MB are ignored, and API calls accept up to 20 documents each. The free Starter plan is free, billed Always; it includes up to 25 developers, 10K API calls per month, up to 500 historical scan detections, and unlimited real-time scanning.

Talisman is a free, open-source Git tool from ThoughtWorks that installs hooks to check outgoing changes for potential secrets before they leave a workstation. It runs as a pre-commit hook, pre-push hook, or standalone executable, with installation options for a global Git hook template, one repository, or the CLI. Detectors inspect encoded values, file contents, file sizes, high-entropy data, possible credit-card numbers, and filenames or extensions. The CLI can scan Git history for secrets that may already be committed and save reports. A .talismanrc file supports ignored files, allowed patterns, custom search patterns, and detector severity settings. Documentation describes integration with the pre-commit framework and Husky, and lists macOS, Linux, and Windows support. When a check finds a possible issue, Talisman reports the affected file and errors. It is MIT licensed and can be used in CI/CD. Documentation notes that forced-push secrets cannot be detected, and interactive ignore-file configuration is available only to non-Windows users.
