# Fiddler AI: The AI Control Plane for Enterprise Agents > Fiddler AI is the enterprise AI Observability and Security platform that delivers unified visibility, context, and control across AI agents, LLM applications, and traditional ML models. With purpose-built Centor Models, real-time guardrails, and comprehensive governance capabilities, enterprises can test, observe, protect, and govern AI at scale; building trustworthy, safe, and high-performing AI systems from development to production. --- ## Platform - [Control Plane for AI Agents](https://www.fiddler.ai/control-plane): The system of trust for AI agents. Delivers standardized telemetry, reliable evaluation, continuous monitoring, enforceable policy, and auditable governance across first-party, third-party, and coding agents; from creation to production. - [AI Observability and Security Platform](https://www.fiddler.ai/ai-observability): The only AI Observability and Security platform that delivers unified observability at enterprise scale, from application to span level, across agents and predictive models. --- ## Core Product Capabilities Fiddler serves as a neutral control plane for compound AI systems with five core pillars: standardized telemetry, reliable evaluation, continuous monitoring, enforceable policy, and auditable governance. The platform supports agentic AI and predictive ML models in one unified, "batteries-included" solution. Unlike observability tools that only show what happened, the Fiddler Control Plane actively governs what agents can do, enforcing enterprise rules in real time and preventing violations before they occur. ### Test and Observe - [Agentic Observability](https://www.fiddler.ai/agentic-observability): End-to-end visibility, context, and control for the agentic lifecycle. Hierarchical visibility from application to session, agent, trace, and span. Evaluate agents with curated golden and challenger datasets; stress-test edge cases in pre-production. - [ML Observability](https://www.fiddler.ai/mlops): Deliver high-performing AI solutions at scale with drift detection, performance monitoring, and explainability. ### Protect - [Fiddler Centor Models](https://www.fiddler.ai/centor-models): Purpose-built, task-specific evaluation models (previously known as Fiddler Trust Models) that power the Fiddler Trust Service. They run entirely in your environment with no external API calls and no add-on fees, return results in under 100ms, and provide 80+ out-of-the-box and customizable metrics, with bring-your-own-judge flexibility. Centor Models eliminate the Trust Tax of external LLM-as-a-Judge costs and cover 100% of traces without sampling. - [Guardrails](https://www.fiddler.ai/guardrails): Protect agentic applications with the industry's fastest guardrails (<100ms latency). Detects hallucinations, toxicity, PII/PHI leakage, and prompt injection attacks in real time. - Control Plane for Coding Agents: Inline PII/PHI and secret redaction plus fleet-wide developer, cost, and token visibility for coding agents. Integrates through the LLM gateway you already operate; no new gateway, no agent-side integration. Enforces on both request and response. ### Govern - [AI Governance, Risk Management, and Compliance - GRC](https://www.fiddler.ai/ai-governance-risk-compliance): Centralized control and accountability for enterprise AI governance. Auditable governance aligned with NIST AI RMF, ISO/IEC 42001, GDPR, HIPAA, NAIC, SR 11-7, and the EU AI Act. - [Responsible AI](https://www.fiddler.ai/responsible-ai): Mitigate bias and build a responsible AI culture. --- ## Industries - [Government](https://www.fiddler.ai/solutions/government): Mission-critical AI for defense and intelligence operations with AWS GovCloud and air-gapped deployment support. - [Healthcare](https://www.fiddler.ai/solutions/healthcare): Deploy agents for clinical care and patient outcomes safely with HIPAA compliance. - [Insurance](https://www.fiddler.ai/solutions/insurance): Scale trusted agents across insurance claims, underwriting, and risk assessment.
