+# Nexus Shield Integration (Sub-10ms Guardrail Proxy)
+
+Nexus Shield provides in-RAM PII sanitization and security guardrails for Portkey-routed LLM requests with sub-10ms overhead.
+
+## Usage with Portkey
+
+You can route your requests through Nexus Shield by specifying its endpoint in your Portkey configuration or setting `base_url`.
+
+```python
+from portkey_ai import Portkey
+
+portkey = Portkey(
+    api_key="PORTKEY_API_KEY",
+    base_url="https://api.nexusshield.ai/v1",
+    custom_headers={"X-API-Key": "nx_live_YOUR_KEY"},
+)
+
+response = portkey.chat.completions.create(
+    model="gpt-4o",
+    messages=[{"role": "user", "content": "Hello, my phone is 555-0199"}],
+)
+
+print(response)
+```
+
+## Features
+
+- **Sub-10ms Overhead:** Real-time RAM pattern evaluation before upstream LLM calls.
+- **Zero-Log PII Redaction:** Sanitizes sensitive information without disk persistence.
