Clutch is the identity security platform for the AI era. As AI agents multiply across the enterprise, the identity landscape has fundamentally changed. Agents inherit human access, act autonomously, and authenticate through the same credentials that have been ungoverned for decades: service accounts, API keys, OAuth apps, tokens, and secrets.Clutch's Identity Lineage® graph maps every non-human identity, AI agent, and secret to its origin, the people connected to it, and the resources it can reach. That context is what makes risk actionable, detection accurate, and governance possible at scale.Built by practitioners. Trusted by Fortune 500 enterprises.
