Arthur AI

Governing the AI agents a company runs

Arthur builds software that lets enterprises see, secure and govern the AI agents they run. The company says its platform brings security, finance and the teams that ship AI onto one control plane, so that AI can be measured, monitored and governed at scale. Buyers on the business side include AI leaders, the people building products, and the teams that handle security, audit and governance.

Finding every agent

Discovery capabilities locate agents wherever they run, on endpoints, in the cloud, in private data centers and elsewhere in a company's compute environment. The platform shows every agent in one inventory, including shadow agents that were set up without approval, so that policies can be enforced across all of them.

Runtime security and alerts

Runtime security adds guardrails and real-time alerting. Arthur's Agent Behavioral Analytics continuously monitors AI applications and flags anomalous behavior, suspicious patterns and indicators of compromise. Findings can be streamed into the security operations tools a team already uses, such as CrowdStrike Falcon, Elastic, Splunk and Datadog.

Observability and evaluation

Observability traces each reasoning step, tool call, retrieval and handoff, so a team can see not only what an agent did but why it did it. The company says its coverage runs across the whole development lifecycle, from prompt experimentation through to continuous evaluation, with step-level traces and global and use-case policies.

Governance, audit and cost control

Governance and compliance tools keep full audit logs and lineage, with continuous risk assessment behind each policy decision. The platform also tracks spending on AI by team and user, and it can detect requests that do not need an expensive model and reroute them, including to open-source models hosted internally.

Deployment and access

The platform can be deployed on premises, in the cloud or in a hybrid setup, with role-based access control and single sign-on. The company says it is trusted by leaders at Fortune 500 companies, which is its own claim, and that its security, audit and governance teams share one system of truth.
