Fiddler AI · Supports System
“Fiddler gives enterprises one control plane to evaluate, monitor, enforce, and govern first-party, third-party, and coding agents, through the gateway enterprises already run. From agent behavior and policy violations to usage, ownership, and spend, teams get the context they need to operate agents safely at scale.”

Fiddler AI · Supports System
“Fiddler Guardrails is the industry’s fastest policy enforcement layer for agentic AI. Define the safety, security, and compliance policies that govern your agents, and Fiddler enforces them at runtime in under 80ms, powered by purpose-built, fine-tuned, and task-specific [Fiddler Centor Models](/centor-models) (formerly known as Fiddler Trust Models). Every prompt and response is evaluated against your thresholds for hallucinations, jailbreaks, PII exposure, and unsafe content, and intercepted before it reaches the user or downstream system”
