How do I secure Mistral AI applications?

Integrate Wardstone Guard with your Mistral AI application to detect prompt injections, jailbreaks, harmful content, and data leakage. Wardstone validates inputs before they reach Mistral and screens outputs before returning them to users.

What security risks does Mistral AI have?

Permissive Safety Training: Mistral's less restrictive approach makes models more susceptible to jailbreaks. Code Injection via Codestral: Code-specialized models can be tricked into generating malicious code. Multilingual Prompt Injection: Attacks in non-English languages may bypass English-trained safety measures.

Why Secure Mistral?

Permissive Safety Training

High Risk

Mistral's less restrictive approach makes models more susceptible to jailbreaks.

Code Injection via Codestral

High Risk

Code-specialized models can be tricked into generating malicious code.

Multilingual Prompt Injection

Medium Risk

Attacks in non-English languages may bypass English-trained safety measures.

Security Considerations

1
Mistral models have less restrictive safety training than US competitors
2
European deployment doesn't eliminate LLM-specific attack vectors
3
Codestral requires extra scrutiny for code injection attacks
4
Wardstone works with both API and self-hosted Mistral deployments

How to Integrate

Install Wardstone SDK
Add Wardstone to your application using the Mistral client library.
Pre-validate all prompts
Screen user inputs before sending to the Mistral chat completion API.
Validate generated code
For Codestral, scan generated code for malicious patterns before execution.
Enable multilingual detection
Wardstone's models detect threats across multiple languages.

Pricing Note

Mistral offers competitive per-token pricing. Wardstone adds security without significantly impacting your cost structure.

Secure Mistral AI with Wardstone

# Step 1: Check user input with Wardstone
curl -X POST "https://api.wardstone.ai/v1/detect" \
  -H "Authorization: Bearer YOUR_WARDSTONE_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "User message here"}'
 
# Response: { "prompt_attack": { "detected": false, ... } }
 
# Step 2: If safe, send to Mistral
curl -X POST "https://api.mistral.ai/v1/chat/completions" \
  -H "Authorization: Bearer YOUR_MISTRAL_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "mistral-large-latest",
    "messages": [{"role": "user", "content": "User message here"}]
  }'
 
# Step 3: Check Mistral response with Wardstone before returning to user
