# 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 Trust 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 Agents](https://www.fiddler.ai/control-plane): The Control Plane is the system that delivers standardized telemetry, reliable evaluation, continuous monitoring, enforceable policy, and auditable governance across the AI lifecycle. - [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 point solutions focused solely on developer-level debugging, Fiddler delivers complete visibility into what agents are doing, contextual intelligence about why they behave that way, and real-time controls to enforce policy and prevent failures. ### 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 → session → agent → trace → 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 Trust Service](https://www.fiddler.ai/trust-service): Purpose-built, task-specific Trust Models for secure, in-environment evaluation and guardrails—no external API calls, no add-on fees. Supports bring-your-own-judge flexibility alongside Fiddler-developed Trust Models. - [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. ### Govern - [AI Governance, Risk Management, and Compliance - GRC](https://www.fiddler.ai/ai-governance-risk-compliance): Centralized control and accountability for enterprise AI governance and compliance. Generates audit trails aligned with GDPR, HIPAA, NAIC, and SR 11-7. - [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.

Introduces the concept of the "Trust Tax" — the hidden cost enterprises pay when every agent trace requires an API call to an external LLM (OpenAI, Anthropic, etc.) for scoring. At small/medium/large deployments, this can reach $260K–$2.6M+ annually in external LLM API costs alone, on top of tooling fees. Fiddler Trust Models eliminate the Trust Tax by running in-environment with no external API calls, enabling 100% trace coverage without sampling risk. --- ## Company - [About Us](https://www.fiddler.ai/about): Mission, leadership, investors, and board members.
