Fiddler AI is an AI observability and guardrails vendor. Its published material describes guardrails that enforce policy inline on an agent's request and response path in under 80ms, stopping violations before data leaves the customer network rather than flagging them afterwards, and states that every enforcement decision is recorded with who triggered it and what happened. It is sold on three plans, with the Developer plan usage-based at $0.002 per trace, and is deployable as SaaS, VPC or on-premises, including AWS GovCloud. The vendor states its users include Fortune 100 organizations in regulated sectors such as financial services, healthcare, insurance and government, and lists inclusion in four Forrester, Gartner and IDC analyst reports. No compliance certificate, auditor or report date is published on the source page, and no insurance cover, customer indemnity, coverage limit, outcome-linked payment or settlement mechanism is published. All statements above are drawn from the vendor's own homepage, which is a primary source for what the vendor claims about itself.
