Fiddler Trust Service for LLM Application Monitoring and Guardrails
Fiddler Trust Service for LLM Application Monitoring and Guardrails


How Fiddler Trust Service Strengthens AI Guardrails and LLM Monitoring
As part of the Fiddler AI Observability and Security platform, the Fiddler Trust Service is an enterprise-grade solution designed to strengthen AI guardrails and LLM monitoring, while mitigating LLM security risks. It provides high-quality, rapid monitoring of LLM prompts and responses, ensuring more reliable deployments in live environments.
Powering the Fiddler Trust Service are proprietary, fine-tuned Fiddler Trust Models, designed for task-specific, high accuracy scoring of LLM prompts and responses with low latency. Trust Models leverage extensive training across thousands of datasets to provide accurate LLM monitoring and early threat detection, eliminating the need for manual dataset uploads. These models are built to handle higher traffic and inferences as LLM deployments scale, ensuring data protection in all environments — including air gapped deployments — and offering a cost-effective alternative to closed sourced models.
Fiddler Trust Models deliver guardrails that moderate LLM security risks, including hallucinations, toxicity, and prompt injection attacks. They also enable comprehensive LLM monitoring and online diagnostics for Generative AI (GenAI) applications, helping enterprises maintain safety, compliance, and trust in AI-driven interactions.

Frequently Asked Questions
What are AI guardrails in Large Language Models?
AI guardrails are predefined rules, policies, and mechanisms that ensure AI models operate within ethical, legal, and safety boundaries. They help prevent harmful outputs, bias, and unintended consequences in AI-driven systems.
Why is LLM monitoring important for AI models?
LLM monitoring is crucial for enterprise LLM deployment, ensuring large language models generate accurate, reliable, and safe responses. It helps detect hallucinations, jailbreak attempts, and performance drift, providing continuous oversight to maintain AI integrity and alignment with business and ethical standards.
How do AI guardrails improve trust and safety?
AI guardrails enhance trust and safety by enforcing customizable content moderation through real-time intervention mechanisms. This reduces the chance of generating a harmful or misleading output, or the success of a jailbreak attempt, ensuring AI systems remain responsible and aligned with user expectations.
How can AI guardrails help businesses stay compliant with regulations?
AI guardrails enforce data privacy, fairness, and ethical guidelines, ensuring compliance with industry regulations such as GDPR, HIPAA, or AI governance frameworks. Automated policy enforcement helps mitigate legal and reputational risks.
What industries benefit most from LLM monitoring?
Any organization relying on automated decision-making can benefit from LLM oversight for risk mitigation; however, for industries like financial seervices, healthcare, Insurance, and Government, LLM monitoring is essential. That's because these industries require close performance and compliance oversight due to strict regulations and sensitive data.
