Fiddler AI

The control plane for trusted enterprise agents and models

Agentic and ML observability

See the performance of every agent and predictive model in a single pane of glass, with every action, token and dollar traceable by user and team.

In-environment guardrails and evaluations

Fiddler Centor Models power policy enforcement and continuous evaluation inside your network, avoiding external LLM API calls and their hidden costs.

Inline policy enforcement

Detects and redacts PII, PHI and secrets on the same request path — before a prompt reaches the model and before a response reaches the developer — with sub-80ms latency.

Auditable AI governance

Keeps a living inventory of every connected agent and records each enforcement decision, with who triggered it and what happened, ready for GRC and AI regulation audits.
