GitGuardian vs KeyHog

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.

KeyHog is free, open-source Rust software for finding and verifying exposed API keys, tokens, passwords, and other credentials. It scans source repositories and Git history, archives, Docker images, URLs and HAR captures, collaboration content, VCS inventories, cloud-storage inventories, browser assets, and running systems. The project lists 934 service-specific detectors, decode-before-scanning, contextual evidence and suppression, and optional live provider verification. GPU execution can use CUDA, native Metal, or portable WGPU, with calibration selecting a parity-backed option. Its GitHub Action scans checked-out trees, fails on high or critical findings, uploads SARIF to Code Scanning, and retains a workflow artifact. Documented CI integrations include GitLab, CircleCI, Jenkins, Buildkite, and shell jobs. A Unix daemon checks changed repository blobs before commits; Windows uses in-process scanning. KeyHog runs on Linux, macOS, Windows, and self-hosted deployments, and requires Rust 1.89 or newer. Code and detector TOMLs are licensed MIT OR Apache-2.0. The plan costs nothing.
