Prevent Chatbot Hallucinations and Injection Attacks

Inspect claims and policy chatbot inputs and outputs to block injected instructions and unsupported answers before policyholders see them.

Prevent Chatbot Hallucinations and Injection Attacks

Customer-facing claims and policy chatbots retrieve documents, emails, and tool outputs to answer questions about coverage and claim status. That content can hide injected instructions, and models can produce confident answers about coverage that are simply wrong. PointGuard AI inspects inputs and outputs in real time, helping carriers block manipulation and unsafe responses before they reach policyholders.

Challenges

Chatbots that sound authoritative can mislead policyholders or be steered by content they retrieve.

  • Uploaded documents and emails can contain hidden instructions.
  • Models can invent coverage terms, limits, or claim outcomes.
  • Keyword filters miss encoded, multilingual, and adaptive attacks.
  • Policyholders may act on an answer before anyone reviews it.

Solution

Runtime Guardrails and AI Red Teaming test chatbot behavior and enforce carrier-defined content policies at runtime.

1. Inspect inputs. Scan prompts, retrieved documents, and tool outputs for injection attempts using fine-tuned detection models at sub-100 ms latency.

2. Enforce response policies. Check generated answers against carrier rules for coverage statements, claim guidance, and restricted topics. Block or escalate responses that violate policy.

3. Test before release. Probe chatbots with coverage, claims, and adversarial scenarios. Review failures before approving a model or prompt change for production.

4. Monitor and retest. Track detections and violations over time. Retest after model, prompt, or knowledge-base changes to catch new failure patterns.

These controls reduce exposure to unsafe content; accurate coverage answers still depend on approved, current policy data.

Risks Addressed

  • OWASP Top 10 for LLMs: LLM01 Prompt Injection, LLM05 Improper Output Handling, and LLM09 Misinformation, covering manipulated inputs and unsupported coverage answers reaching policyholders.
  • OWASP Top 10 for Agentic Applications: ASI01 Agent Goal Hijack and ASI09 Human-Agent Trust Exploitation, addressing hijacked chatbot goals and misplaced policyholder trust.
  • NIST AI RMF: MAP defines permitted uses; MEASURE tests resistance and accuracy; MANAGE blocks failures; GOVERN assigns review responsibilities.
