detect-secrets review
A free, baseline-driven Git scanner with flexible detectors and developer workflow hooks.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
detect-secrets is an open-source Python module from Yelp for finding potential secrets in repositories and code files. It is aimed at developers and security teams working with Git-based development workflows who want a free scanning layer across Linux, macOS, and Windows. The project detects possible credentials using regex-based, entropy-based, and keyword-based detectors, with built-in plugins for secret types associated with services such as AWS, GitHub, GitLab, Slack, Stripe, and Twilio.
Its strongest capability is baseline-driven review. Findings can be recorded in a baseline, audited over time, and labeled as true or false positives. Inline allowlisting, configurable exclusion filters, plugin tuning, custom filters, and custom detector plugins give teams control over how scanning behaves in their codebases. Staged-file checks through a command-line hook and integration with the pre-commit framework help place checks inside the developer workflow, while optional network-based verification adds another way to assess detected secrets.
The trade-off is a focused, integration-led approach rather than a broad platform experience. The published capabilities center on repository and file scanning, Git workflows, pre-commit checks, and command-line CI/CD usage. Teams should expect to manage baselines and shape the rules around their repositories, especially when handling false positives or organization-specific secret formats. detect-secrets fits developers who want open-source control and a configurable foundation for preventing new secrets from entering repositories. Teams seeking a wider built-in ecosystem or a dedicated pull-request interface should consider a different category of tool.
