Arthur | AI governance for everyone

AI governance for everyone.

Arthur enables teams to detect, govern, and improve AI — built for enterprise security, audit, governance, engineering, and product teams.

An enterprise system to manage and control your AI initiatives.

Arthur empowers teams with the tools to oversee both internal and third-party AI running across their organization.

Agent Security & Governance
Find every agent in your environment, assign ownership and risk, and enforce policies at the scale of thousands of agents.

Automated discovery across OTEL, MCP, network & cloud APIs
Risk scoring, ownership & policy enforcement
SOC 2, RBAC, SSO, BAA & immutable audit logs

Agent Development Toolkit
Version prompts, run structured experiments, trace every run, and catch regressions before users do — with no changes to your stack.

Versioned prompts & one-click rollback
A/B experiments on real production data
Full-trace observability & live evals on OTEL

Ensure reliability and security of AI across your organization.

Governance and security teams leverage Arthur to discover, govern, and apply policies to AI org-wide. Engineering and product teams build reliably along the Agent Development Lifecycle.

Core capabilities

AI Performance Evaluations
Automated pass/fail judgments on every interaction — the primitive guardrails, experiments, and governance all run on.

Agentic Observability & Tracing
Capture the full reasoning chain — every LLM call, tool, and retrieval — across every step of a run.

Policies and Guardrails
The same evals, enforced synchronously, pre- and post-LLM, with an action attached to every judgment.

Across any AI, anywhere it runs

Any AI, Any Use Case
Model-, framework-, and use-case-agnostic. ML, GenAI, and agentic systems are governed on one platform, so no agent escapes the perimeter.

Flexible Deployment
SaaS, hybrid, or on-prem. Options so that data never leaves your system. Professional services available to ensure enterprise-grade deployment.

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.

24/7 Continuous oversight: Every agent discovered and every interaction evaluated, around the clock.
100% Accountable agents: Every discovered agent gets an owner, a risk class, and an enforced policy.
0 Silent regressions: Evals catch quality and safety drift before it ever reaches your users.

Bring comprehensive AI oversight to your organization.

Trusted by enterprise AI teams

“Arthur has given us peace of mind — it's a one-stop-shop for all our model monitoring needs. Arthur will drop our maintenance workload by 50%.”

“Arthur's integration framework reinforced best practices for our data artifacts and was seamless to set up. Our first production model in Arthur went from 'idea' to 'implemented' in a few hours.”
