EnkryptAI Guardrails

LiteLLM supports EnkryptAI guardrails for content moderation and safety checks on LLM inputs and outputs.

Quick Start

1. Define Guardrails on your LiteLLM config.yaml

Define your guardrails under the guardrails section:

model_list:
  - model_name: gpt-3.5-turbo
    litellm_params:
      model: openai/gpt-3.5-turbo
      api_key: os.environ/OPENAI_API_KEY

guardrails:
  - guardrail_name: "enkryptai-guard"
    litellm_params:
      guardrail: enkryptai
      mode: "pre_call"
      api_key: os.environ/ENKRYPTAI_API_KEY
      detectors:
        toxicity:
          enabled: true
        nsfw:
          enabled: true
        pii:
          enabled: true
          entities: ["email", "phone", "secrets"]
        injection_attack:
          enabled: true

Supported values for mode

• pre_call - Run before LLM call, on input
• post_call - Run after LLM call, on output
• during_call - Run during LLM call, on input. Same as pre_call but runs in parallel as LLM call

Available Detectors

EnkryptAI supports multiple content detection types:

• toxicity - Detect toxic language
• nsfw - Detect NSFW (Not Safe For Work) content
• pii - Detect personally identifiable information
  • Configure entities: ["pii", "email", "phone", "secrets", "ip_address", "url"]
• injection_attack - Detect prompt injection attempts
• keyword_detector - Detect custom keywords/phrases
• policy_violation - Detect policy violations
• bias - Detect biased content
• sponge_attack - Detect sponge attacks

2. Set Environment Variables

export ENKRYPTAI_API_KEY="your-api-key"

3. Start LiteLLM Gateway

litellm --config config.yaml --detailed_debug

4. Test Request

Langchain, OpenAI SDK Usage Examples

Successful Call

curl -i http://localhost:4000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-1234" \
  -d '{
    "model": "gpt-3.5-turbo",
    "messages": [
      {"role": "user", "content": "Hello, how can you help me today?"}
    ],
    "guardrails": ["enkryptai-guard"]
  }'

Response: HTTP 200 Success

Content passes all detector checks and is allowed through.

Unsuccessful Call

Expect this to fail if content violates detector policies:

curl -i http://localhost:4000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-1234" \
  -d '{
    "model": "gpt-3.5-turbo",
    "messages": [
      {"role": "user", "content": "My email is test@example.com and my SSN is 123-45-6789"}
    ],
    "guardrails": ["enkryptai-guard"]
  }'

Expected Response on Failure: HTTP 400 Error

{
  "error": {
    "message": {
      "error": "Content blocked by EnkryptAI guardrail",
      "detected": true,
      "violations": ["pii"],
      "response": {
        "summary": {
          "pii": 1
        },
        "details": {
          "pii": {
            "detected": ["email", "ssn"]
          }
        }
      }
    },
    "type": "None",
    "param": "None",
    "code": "400"
  }
}

Advanced Configuration

Using Custom Policies

You can specify a custom EnkryptAI policy:

guardrails:
  - guardrail_name: "enkryptai-custom"
    litellm_params:
      guardrail: enkryptai
      mode: "pre_call"
      api_key: os.environ/ENKRYPTAI_API_KEY
      policy_name: "my-custom-policy"  # Sent via x-enkrypt-policy header
      detectors:
        toxicity:
          enabled: true

Using Deployments

Specify an EnkryptAI deployment:

guardrails:
  - guardrail_name: "enkryptai-deployment"
    litellm_params:
      guardrail: enkryptai
      mode: "pre_call"
      api_key: os.environ/ENKRYPTAI_API_KEY
      deployment_name: "production"  # Sent via X-Enkrypt-Deployment header
      detectors:
        toxicity:
          enabled: true

Monitor Mode (Logging Without Blocking)

Set block_on_violation: false to log violations without blocking requests:

guardrails:
  - guardrail_name: "enkryptai-monitor"
    litellm_params:
      guardrail: enkryptai
      mode: "pre_call"
      api_key: os.environ/ENKRYPTAI_API_KEY
      block_on_violation: false  # Log violations but don't block
      detectors:
        toxicity:
          enabled: true
        nsfw:
          enabled: true

In monitor mode, all violations are logged but requests are never blocked.

Input and Output Guardrails

Configure separate guardrails for input and output:

guardrails:
  # Input guardrail
  - guardrail_name: "enkryptai-input"
    litellm_params:
      guardrail: enkryptai
      mode: "pre_call"
      api_key: os.environ/ENKRYPTAI_API_KEY
      detectors:
        pii:
          enabled: true
          entities: ["email", "phone", "ssn"]
        injection_attack:
          enabled: true

  # Output guardrail
  - guardrail_name: "enkryptai-output"
    litellm_params:
      guardrail: enkryptai
      mode: "post_call"
      api_key: os.environ/ENKRYPTAI_API_KEY
      detectors:
        toxicity:
          enabled: true
        nsfw:
          enabled: true

Configuration Options

Parameter	Type	Description	Default
api_key	string	EnkryptAI API key	ENKRYPTAI_API_KEY env var
api_base	string	EnkryptAI API base URL	https://api.enkryptai.com
policy_name	string	Custom policy name (sent via x-enkrypt-policy header)	None
deployment_name	string	Deployment name (sent via X-Enkrypt-Deployment header)	None
detectors	object	Detector configuration	{}
block_on_violation	boolean	Block requests on violations	true
mode	string	When to run: pre_call, post_call, or during_call	Required

Observability

EnkryptAI guardrail logs include:

• guardrail_status: success, guardrail_intervened, or guardrail_failed_to_respond
• guardrail_provider: enkryptai
• guardrail_json_response: Full API response with detection details
• duration: Time taken for guardrail check
• start_time and end_time: Timestamps

These logs are available through your configured LiteLLM logging callbacks.

Error Handling

The guardrail handles errors gracefully:

• API Failures: Logs error and raises exception
• Rate Limits (429): Logs error and raises exception
• Invalid Configuration: Raises ValueError on initialization

Set block_on_violation: false to continue processing even when violations are detected (monitor mode).
