     Cyata is the Control Plane for Agentic Identity. Cyata takes a posture-first approach - discover, explain, and control every AI agent in your environment. This enables governance at scale - organizations can enforce posture guardrails that adapt to risk levels and establish context-aware access controls. The result - preemptive security where every agent action is attributable and audit-ready, not shadow risk.
