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.

LLM-powered email governance, security and sustainable archiving for the enterprise
Capture, index and preserve email content and attachments in governed storage so they remain retrievable for legal, audit and compliance needs.
Use large language model intelligence to classify messages and flag sensitive or regulated content as it moves through the mail flow.
Apply policies that identify risky or sensitive data leaving the organisation and enforce handling rules automatically.
Connect Microsoft 365 and Google Workspace mailboxes with managed cloud storage integrations, including Box, to keep content under retention control.
