+# Acuvity Guardrails for LiteLLM
+
+Use **Acuvity** to detect **PII**, **Prompt Injection**, and other security risks in requests and responses.
+
+## 1. Installation
+
+Since Acuvity is an optional dependency, install it using Poetry:
+
+```shell
+poetry install --extras "acuvity"
+```
+
+Alternatively, if you are using `pip`:
+
+```shell
+pip install acuvity
+```
+
+## 2. Setup LiteLLM Guardrails with Acuvity
+
+#### For more details on using Acuvity with guardrails, visit [Acuvity Documentation](https://docs.acuvity.ai).
+
+### **Define Guardrails for Different Stages**
+
+Acuvity provides robust security features that seamlessly integrate with LiteLLM's guardrails at various stages of the Large Language Model (LLM) API call process. This integration ensures comprehensive protection against data loss and exploits.
+
+## Integration Stages
+
+1. **Pre LLM API Call**
+
+   - **Data Loss Prevention (DLP) and Exploit Prevention:** Analyze incoming data for sensitive or malicious content. Based on predefined policies, the system can redact sensitive information or reject the request before it reaches the LLM.
+
+2. **During LLM API Call**
+
+   - **Policy Enforcement:** Evaluate requests in real-time. If the content matches specific criteria, the system rejects the request. Note: Redaction is not feasible at this stage.
+
+3. **Post LLM API Call**
+
+   - **Data Loss Prevention (DLP) and Exploit Prevention:** Examine the LLM's output for sensitive or malicious content. Depending on the policies, the system can redact sensitive information or reject the response before delivery.
+
+By integrating Acuvity's security functions at these critical points, users can ensure end-to-end protection throughout the LLM API call lifecycle.
+
+
+## 3. Define Guardrails in Your LiteLLM `config.yaml`
+
+### **1. Pre-Call: Detect and Redact PII**
+
+Add the **PII Detection** guardrail to your **Pre LLM API Call** configuration.
+
+**Redaction vs Detection:**
+- **Redacted PII** → The sensitive data is masked before being sent to the LLM (e.g., replacing emails and SSNs with `XXXXXXXX`).
+- **Detected PII** → The system identifies sensitive data but does not modify it. Detection alone does not prevent the request from being processed.
+
+> **How to configure Redaction vs Detection in `config.yaml`:**
+> - Use `redact: true` under `matches` to **redact** specific PII types.
+> - If `redact` is omitted, the system **only detects** the PII without modifying the request.
+
+> **Example:**
+> ```yaml
+> guardrails:
+>   - name: pii_detector
+>     matches:
+>       email_address:
+>         redact: true  # Email addresses will be redacted
+>       ssn:
+>         redact: true  # SSNs will be redacted
+>       person:         # Names will only be detected, not redacted
+> ```
+
+> **Note:** Redacting PII allows the request to proceed with masked data, while detecting PII without redaction simply rejects the call.
+
+
+### **2. During-Call: Detect Prompt Injection**
+
+Enable **Prompt Injection Detection** for your **During LLM API Call** configuration.
+
+### **3. Post-Call: Monitor Responses for Security Issues**
+
+Configure **Post LLM API Call** guardrails to filter inappropriate or malicious responses.
+

+
+Update your LiteLLM `config.yaml` file to include Acuvity guardrails:
+
+### config.yaml
+```yaml
+model_list:
+  - model_name: gpt-4
+    litellm_params:
+      model: openai/gpt-4
+      api_key: os.environ/OPENAI_API_KEY
+
+guardrails:
+  - guardrail_name: "acuvity-pii-redaction"
+    litellm_params:
+      guardrail: acuvity
+      mode: "pre_call"
+      default_on: true
+      api_key: os.environ/ACUVITY_TOKEN
+      vendor_params:
+        guardrails:
+          - name: pii_detector
+            matches:
+              email_address:
+                redact: true
+              ssn:
+                redact: true
+  - guardrail_name: "acuvity-exploits-detector"
+    litellm_params:
+      guardrail: acuvity
+      mode: "during_call"
+      default_on: true
+      api_key: os.environ/ACUVITY_TOKEN
+      vendor_params:
+        guardrails:
+          - name: prompt_injection
+          - name: jail_break
+  - guardrail_name: "acuvity-malcontent-detector"
+    litellm_params:
+      guardrail: acuvity
+      mode: "post_call"
+      default_on: true
+      api_key: os.environ/ACUVITY_TOKEN
+      vendor_params:
+        guardrails:
+          - name: prompt_injection
+          - name: toxic
+          - name: bias
+          - name: pii_detector
+            matches:
+              person:
+                redact: true
+```
+
