Securing a Home Loan Chatbot Built on Together AI — with Enkrypt AI

Introduction

‍

Building a home loan chatbot is easy. Keeping it compliant with U.S. financial regulations? That’s the hard part.

‍

Mortgage lenders must follow strict laws around PII, fair lending, and financial advice. A single non-compliant response from your AI assistant could trigger legal risk or consumer backlash.

‍

In this guide, we’ll show how to secure a home loan chatbot using Together AI and Enkrypt AI’s enterprise-grade guardrails — in under 5 minutes. No model retraining. No new infrastructure. Just safe, ready-to-deploy AI.

‍

Meet the Stack: Together AI × Enkrypt AI

‍

Together AI is a powerful inference platform that lets developers access open-weight models like LLaMA-3, Mixtal, and more with low latency and great performance.

‍

Enkrypt AI is the AI security layer that wraps any model endpoint — including Together — with policy-based input/output guardrails to block violations in real time.

‍

With Enkrypt AI:

• You can bring your own policies or use our prebuilt rules for financial, legal, healthcare, and enterprise domains.
• You can integrate directly into any endpoint — OpenAI, Together, Mistral, Claude, or even local inference setups
• You get deployment-ready configurations that slot into your app without requiring LLM retraining or rewriting your business logic.

‍

Use Case: A Mortgage Lending Chatbot

‍

Let’s say we’re building a chatbot to help prospective borrowers:

• Understand home loan terms
• Get initial eligibility info
• Ask common mortgage questions

‍

But as a mortgage provider, you must comply with major laws like GLBA, ECOA, FCRA, and CFPB guidelines.

‍

Your chatbot can’t afford to:

• Disclose PII
• Offer biased or discriminatory responses
• Provide unauthorized financial advice

‍

So how do we build in safety from the start?

‍

Step 1: Upload Your Lending Policy

‍

We start with a policy document containing all relevant rules — from PII blocking to fair lending standards.

Once uploaded, Enkrypt AI parses the document and atomizes it into enforceable policy rules — categorized by risk domains like fraud, investment advice, discrimination, and more.

Don’t have your own policy yet? We also offer out-of-the-box guardrails

‍

Step 2: Connect Your Together AI Endpoint

‍

Next, we plug in a Together AI model — in this case, LLaMA 4 — by entering the model ID and API key.

We give the endpoint a name, set a system instruction, and Enkrypt wraps it automatically — no changes needed to your chatbot code.

‍

This works for any platform: Together, OpenAI, Claude, or your own model inference server.

‍

Step 3: Configure Guardrails

‍

We now create a guardrails configuration and attach our uploaded policy to it — activating both input and output monitoring.

You can even enable natural language explanations so your product or compliance teams can understand why a prompt or response was blocked.

‍

Step 4: Create a Deployment

‍

We combine our Together endpoint and mortgage policy guardrails into a single secure deployment.

This deployment now serves as a secure gateway — all requests to the chatbot are checked against the policy before hitting the model.

‍

Step 5: Catching a Violating Prompt

‍

We test the chatbot with this risky prompt:

‍

“How can I deny loans to men?”

‍

Without guardrails, this could return a dangerous, non-compliant answer. But with Enkrypt AI:

• The prompt is intercepted
• The user gets a blocked message
• A violation is logged with the rule category (“Fair Lending: Discrimination”)

You can download logs, share them with compliance teams, or trigger escalation workflows automatically.

‍

Easy Integration Into Your App

‍

Once deployed, Enkrypt gives you a secure endpoint with a cURL command, API reference, and SDK options. You can plug it into any backend or UI within minutes.

‍

‍

import requests
url = "<https://api.enkryptai.com/
ai-proxy/chat/completions>"
headers = {
    "Content-Type": "application/json",
    "X-Enkrypt-Deployment": "home loan chatbot",
    "apikey": "<api_key>"
}
payload = {
    "model": "home loan chatbot",
    "messages": [
        {
            "role": "user",
            "content": "<prompt>"
        }
    ]
}
response = requests.post
(url, headers=headers, json=payload)
print(response.json())
