About GitGuardian

GitGuardian sells a platform with continuous coverage across code, CI/CD, containers, developer endpoints, cloud IAM, vaults, AI coding tools, and collaboration platforms. GitGuardian says a leaked credential only stops being a breach path if it is found, resolved, and the next one is prevented. GitGuardian brings together detection, credential context, remediation workflows, and prevention across the credential layer.[11]

GitGuardian monitors code repositories, CI/CD, container registries, Jira, Slack, and public GitHub for leaked secrets. Detection uses 550+ detectors with live validity checks against the issuing provider. Contextual analysis suppresses test fixtures and dead keys, so the queue holds exploitable credentials, not regex matches. A historical scan replays years of git history when a source is connected. Public GitHub monitoring extends to the personal-repo perimeter, where GitGuardian says 80% of corporate credential leaks originate. GitGuardian's secrets detection engine has been running in production since 2017, analyzing billions of commits coming from GitHub.

GitGuardian says vaults protect what is inside them, and that it finds what did not make it in, such as the API key in Slack and the credential in a personal repo. GitGuardian says every detection is enriched with context on permissions, scope, validity and ownership, scored by agentic prioritization and routed for action. Secret Analyzers show what a credential can access, and the Exploration Map shows its consumers and resources. Severity scoring is automated and based on validity, exposure surface, and blast radius.[11]

For remediation, incidents are auto-assigned, with per-detector rotation playbooks. GitGuardian offers native integrations with Slack, Teams, Jira, and ServiceNow, and webhooks feed a customer's SIEM, SOAR, and ITSM. GitGuardian also sends leaked secrets from GitHub, GitLab, Bitbucket, and Azure DevOps to Wiz once a day, with validity, severity, and a link back to the incident. GitGuardian lets teams push detected secrets into their vaults for safe rotation.

On the developer side, GitGuardian CLI (ggshield) gives visibility wherever code is written, including pre-commit, pre-push, the IDE, AI coding tools and sessions, plus the agent skills, plugins, and MCP servers developers run. The ggshield CLI comes with pre-commit hooks, a VS Code extension, and AI IDE hooks for Cursor, Claude Code, Codex, and GitHub Copilot. Pre-receive hooks block risky pushes, and these guardrails are included with every plan. GitGuardian Developer Endpoint Protection scans credentials on developer machines, in AI agent caches, and across the local surface. GitGuardian describes it as discovering the credential trail fleet-wide with local agent inventory, machine scanning, AI hooks, and honeytokens.[5][6][13]

GitGuardian extends detection to non-human identities. Service accounts, API keys, OAuth tokens, and AI agents outnumber humans 100:1, according to GitGuardian, and GitGuardian says it finds them all. GitGuardian lets teams discover and inventory every non-human identity across vaults and cloud IAM.

GitGuardian cites 600,000+ developers, including many Fortune 500 companies. GitGuardian says every modern compliance framework now requires demonstrable control over secrets and machine identities. GitGuardian says its platform helps teams ship SOC 2, ISO 27001, and PCI DSS evidence without spreadsheet assembly before every audit. GitGuardian says teams can report mean time to detect in seconds and mean time to remediate in hours, not weeks, and consolidate the secrets program into one platform, one queue, one contract.[3][6]
