Product comparison
Verdictan vs. Arthur AI
You need teams to operate AI systems with measurable quality, enforceable policy, and reviewable evidence.
Why Verdictan
Verdictan applies policy at the gateway and records request-level decision evidence for supported AI traffic. Run it in a self-hosted or air-gapped environment.
Key differences
Verdictan vs. Arthur AI Platform: Key differences
Verdictan governs supported model traffic, while Arthur evaluates, monitors, and governs models and agents across their lifecycle.
Arthur evaluates before and after deployment
The platform supports preproduction tests, runtime guardrails, and continuous production evaluations.
The evaluation engine can remain near customer data
Arthur documents a data plane in the customer environment and a centralized control plane for metrics and management.
OpenTelemetry traces preserve each meaningful step
Arthur models LLM, retriever, tool, agent, chain, embedding, reranker, and guardrail spans.

Common questions
What to ask before you decide
Does Arthur support OpenTelemetry traces?
Yes. Arthur uses OpenTelemetry ingestion with OpenInference semantic conventions.
Can Arthur keep inference data in a customer environment?
Arthur documents a local data plane that sends only metrics and metadata to its control plane.
Does Arthur provide runtime guardrails?
Yes. Arthur documents configurable checks for several sensitive data, safety, injection, and hallucination risks.
Can governance require human review?
Yes. Arthur policies can include attestation requirements at configured intervals.
What should the pilot measure?
Measure trace coverage, evaluator agreement, guardrail latency, alert precision, attestation completion, and gateway policy behavior.
How we researched this page
We checked the official sources below on Aug. 11, 2026. Product scope, plan access, beta status and support can change.
- Confirm deployment packaging, supported connectors, trace sampling, evaluation costs, guardrail latency, and control-plane data fields.
- Validate custom evaluators and guardrails against domain test sets before broad enforcement.
- Test Arthur and Verdictan policy paths separately because each product applies controls at a different boundary.
