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.

Attack-led AI security testing and red teaming
Agent-native reconnaissance maps models, agents, tools, instructions, permissions and behaviours the way an attacker would before launching attacks.
Continuous, adaptive testing of AI agents and systems against evolving attack techniques, rather than one-off audits.
Findings are backed by a knowledge base built from more than 175 publicly disclosed AI vulnerabilities across major AI systems.
Runtime protections and remediation guidance help close defensive gaps and verify that fixes actually hold.
