GitGuardian vs Secretlint

GitGuardian helps enterprises find leaked secrets and manage non-human identities and AI agent security. Internal Secrets Monitoring looks across code, CI/CD, and collaboration tools, while Public Secrets Monitoring detects secrets exposed on public GitHub. Repository scans can run in real time or historically, and the ggshield command-line tool supports scanning during development, including pre-commit hooks. Listed capabilities also include CI/CD, pull-request, and push-protection scanning, plus custom detection rules. Growth includes remediation playbooks, Slack, Jira, and ServiceNow integrations, AI risk scoring, and false-positive filtering. Enterprise adds non-human identity governance and self-hosted deployment through GitGuardian Bridge, with Helm or KOTS deployment support. Supported version-control systems include GitHub, GitLab, Bitbucket, and Azure DevOps. Starter is free for up to 25 developers, with unlimited real-time scanning, up to 500 historical scan detections, and 10,000 API calls per month. Growth and Enterprise pricing requires contacting sales; a 30-day trial is listed.

Secretlint is a free, MIT-licensed, open-source linting tool for finding credentials in projects and helping prevent commits that contain them. Its command-line interface scans files, glob patterns, or standard input. Detection rules are separate modules, and custom rules can be distributed as npm packages. Secret values are masked in lint error messages by default, reducing exposure in terminal output and logs. Secretlint supports Git workflows, including pre-commit integrations with Husky and lint-staged, pre-commit, and Git hooks. Documentation covers GitHub Actions checks and pull-request annotations through the GitHub formatter. Listed integrations also include Mega-Linter, SARIF formatting, a browser extension, and a macOS clipboard app. The WebExtension works with Chrome and Firefox DevTools to help notice credentials in requests and responses. Installation options include Node.js, Docker, or a single executable without Node.js; the Node.js route requires version 22 or later. It detects secrets but does not automatically fix them.
