Arthur Governance
See every agent. Understand how it works.
Arthur shows you every agent running in your enterprise, then opens up its inner workings. Full observability traces each reasoning step, tool call, retrieval, and handoff, so you can see not just what an agent did but why it did it.
- Every agent visible in one inventory, including shadow agents
- Step-level traces of reasoning, tools, and retrieval
- Global and use-case policies enforced everywhere

Live in minutes. Watching around the clock.
Deploy guardrails and security policies for real-time protection, fast. Arthur's Agent Behavioral Analytics (ABA) continuously monitors every AI application running in your company and immediately alerts on anomalous behavior, suspicious patterns, and indicators of compromise.
Stream findings to the tools your SOC already lives in.
Cost control
Token costs, back under control.
Track spending by team and user. Requests that don't need the expensive model are automatically detected and rerouted, including to internally-hosted open-source models. One pane of glass to monitor and control AI utilization while ensuring quality of service.
Only 25% of AI projects return their investment.
The gap is rarely the model; it's the lack of a shared system between the people who govern AI and the people who build it.
