Leading Healthcare Payer Scales GenAI Safely with >10x TCO Improvement

A leading healthcare payer with 200+ GenAI applications in production needed to scale safely while meeting strict HIPAA, CMS, and NIST requirements. Manual governance consumed 5-7 FTEs per use case at $950K+ per application. AI tools for health plan members were blocked entirely due to PHI leakage and hallucination risk. Fiddler Guardrails delivered policy-based, real-time protection, and because Trust Models run in-environment with no external API calls, scale without adding hidden costs.

The Challenge: Scaling AI Manually

With 200+ GenAI applications already in production and ambitions to scale to 15 million requests per day, the organization faced a governance gap. AI tools for health plan members, including benefits inquiries, claims status, and self-service support, were blocked entirely due to PHI leakage, hallucination, and brand reputation concerns. Manual, per-application controls could not keep pace with the organization's GenAI growth.

• 5-7 engineering and compliance FTEs required per use case
• $950K+ custom guardrail build cost per use case
• 40-60 hours per month spent on audit prep
• 2-3 month delays due to safety checks blocking innovation

The Solution: Fiddler Guardrails

Fiddler Guardrails delivered policy-based, real-time protection that enabled the organization to scale GenAI safely across 200+ applications.

• Policy-Based Enforcement Across Models: HIPAA filters, PII blocking, and safety controls applied across LLM applications without bespoke development
• Real-Time PHI and PII Detection: Fiddler Trust Models detect and redact sensitive data in real time; running in-environment with no external API calls, eliminating both regulatory exposure and evaluation costs at scale
• Audit Logging and Traceability: Every LLM output, guardrail violation, and response modification logged for state and federal audit support
• Jailbreak and Prompt Injection Defense: Built-in detection for malicious input manipulation‍
• Hallucination and Toxicity Filtering: Faithfulness scoring and response filtering ensure outputs stay aligned with source data

Business Results

Two Weeks to Production, Down from Three Months

‍GenAI initiatives that previously stalled in 2-3 month compliance reviews now move to production in under 2 weeks. The organization moved from blocking AI for health plan members entirely to enabling chatbots and voice-based tools for benefits, claims, and self-service support. Internal agent augmentation tools now ramp new call center staff faster, with 66% fewer incorrect responses surfacing to members.

200+ Applications, One Unified Governance Layer

The organization now operates 200+ GenAI applications under unified Fiddler governance, with infrastructure designed to handle 15 million requests per day. Policy-based controls that once required custom builds for each application now deploy across the full portfolio, eliminating redundant engineering effort.

75% Cost Reduction Per Use Case

Per-use-case cost dropped from $950K+ to under $225K, a reduction of roughly 75%. The shift from bespoke, per-application controls to reusable policy-based guardrails eliminated the need for 5-7 dedicated FTEs per use case. Audit prep that once consumed 40-60 hours monthly now takes under 10 hours, freeing compliance staff to focus on higher-value work. 

In total, the shift to Fiddler Guardrails reduced estimated annual costs from over $6M to under $500K inclusive of the platform. At 15 million requests per day, if this healthcare payer were to rely on external LLM calls for evaluation, they would add millions more in API costs on top of platform fees. Instead, they used Fiddler Trust Models, which run in-environment, producing greater than 10x improvement in TCO.

Real-Time Protection Against PHI, Hallucinations, and Liability

Real-time PHI detection and hallucination filtering reduced the organization's exposure to incidents that previously carried $1M+ remediation costs. Claims workflows now complete 60% faster with fewer legal review cycles, and compliance teams have instant audit traceability for state and federal reviews, replacing manual evidence-gathering that previously delayed every release.

Looking Ahead: From Internal Tools to Member-Facing AI Applications

With Guardrails operating as a reusable policy layer, the healthcare payer is now turning to use cases that compliance barriers previously made impossible. AI agents, chatbots, and voice tools for health plan members, covering benefits inquiries, claims status, and self-service support, have been on hold due to PHI and hallucination risk. That blocker is now resolved.

The next phase focuses on extending the same policy controls across HR, Clinical, Claims, and IT without bespoke engineering for each deployment, and expanding into voice and multimodal interfaces for call center workflows. With unified governance already in place, the roadmap conversation has shifted from risk and compliance to what to build next.
