Product comparison
Verdictan vs. Fiddler AI
You need to detect quality, safety, drift, and performance problems before they affect more users.
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. Fiddler AI Guardrails: Key differences
Verdictan governs supported model traffic, while Fiddler monitors and evaluates traditional models, LLM applications, and agents.
Fiddler monitors several AI system types
Its platform covers traditional machine learning, LLM applications, RAG systems, and agents.
Enrichments add quality and safety signals
Fiddler computes metrics over prompts, context, responses, source documents, and observed agent data.
Verdictan governs the supported request path
The gateway applies configured policy and records evidence before supported model traffic completes.

Common questions
What to ask before you decide
Does Fiddler monitor AI agents?
Yes. It documents integrations for LangGraph, Strands Agents, OpenTelemetry, and a custom SDK.
Can Fiddler monitor RAG systems?
Yes. Fiddler analyzes prompts, retrieved context, source documents, responses, and related metrics.
Does Fiddler support air-gapped use?
Its monitoring overview documents an air-gapped option for the Trust Service.
Can teams define custom LLM evaluators?
Yes. Prompt specifications define structured evaluators with validation and version history.
What should the pilot measure?
Measure ingestion coverage, enrichment quality, alert precision, root-cause speed, guardrail latency, 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 supported integration versions, evaluator costs, sampling, retention, alert limits, and private deployment requirements.
- Validate enrichments against domain labels before teams use them for automated decisions.
- Test Fiddler guardrails and Verdictan gateway policy independently because their documented control paths differ.
