The control plane for trusted enterprise agents and models
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.
Fiddler Centor Models power policy enforcement and continuous evaluation inside your network, avoiding external LLM API calls and their hidden costs.
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.
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.

Turn policies into AI-enforced workflows you can prove
Centralise policies and SOPs with version control and governance mapped to frameworks such as ISO 9001, SOC 2, SOX and FDA requirements.
Turn policies into structured workflows with owners, due dates, conditional logic and approvals, so every step is followed rather than assumed.
Monitors regulatory changes, automates the associated work and flags risks and gaps before they turn into audit findings.
Records who completed each step and when, with required file uploads, form entries and approvals attached to the task.
