GitGuardian is a code and secrets security platform that detects exposed credentials such as API keys, tokens, and passwords across source code, repositories, CI/CD pipelines, and public GitHub. It has expanded into centralized non-human identity (NHI) governance, giving enterprises visibility and control over the machine and AI agent credentials proliferating across their infrastructure. Founded in Paris in 2017 by Eric Fourrier and Jeremy Thomas while they were working as data scientists and engineers, the company became the #1 security app on the GitHub Marketplace and now protects more than 600,000 developers. In February 2025 GitGuardian raised a $50M Series C led by Insight Partners to expand into NHI and AI agent security, bringing total funding to roughly $106M. Investors include Insight Partners, Balderton Capital, and Eurazeo.
