+## 🛡️ Security
+
+0http-bun is designed with **security-first principles** and includes comprehensive protection against common web vulnerabilities. Our middleware and core framework have been thoroughly penetration-tested to ensure production-ready security.
+
+### 🔒 Built-in Security Features
+
+#### **Input Validation & Sanitization**
+
+- **Size Limits**: Configurable limits prevent memory exhaustion attacks
+- **ReDoS Protection**: Restrictive regex patterns prevent Regular Expression DoS
+- **JSON Security**: Nesting depth limits and safe parsing practices
+- **Parameter Validation**: Maximum parameter counts and length restrictions
+
+#### **Attack Prevention**
+
+- **Prototype Pollution Protection**: Filters dangerous keys (`__proto__`, `constructor`, `prototype`)
+- **Safe Property Access**: Uses `Object.prototype.hasOwnProperty.call()` for secure property access
+- **Memory Exhaustion Prevention**: Strict size limits and cleanup mechanisms
+- **DoS Mitigation**: Rate limiting and request throttling capabilities
+
+#### **Error Handling**
+
+- **Sanitized Error Messages**: Prevents information disclosure in production
+- **Custom Error Handlers**: Flexible error handling with type-based responses
+- **Secure Defaults**: Safe 404 and 500 responses without stack traces
+
+#### **Authentication & Authorization**
+
+- **JWT Security**: Proper token validation with comprehensive error handling
+- **API Key Authentication**: Secure key validation with custom validator support
+- **Path Exclusion**: Flexible authentication bypass for public routes
+- **Token Extraction**: Secure token retrieval from headers and query parameters
+
+#### **Rate Limiting**
+
+- **Sliding Window**: Precise rate limiting with memory-efficient implementation
+- **IP-based Keys**: Smart key generation with proxy support
+- **Memory Cleanup**: Automatic cleanup of expired entries
+- **Configurable Limits**: Flexible rate limiting with skip functions
+
+#### **CORS Security**
+
+- **Origin Validation**: Dynamic origin checking with proper Vary headers
+- **Credential Safety**: Prevents wildcard origins with credentials
+- **Preflight Handling**: Comprehensive OPTIONS request processing
+- **Header Security**: Proper CORS header management
+
+### 📊 Security Assessment
+
+- **✅ No Critical Vulnerabilities**
+- **✅ No High-Risk Issues**
+- **✅ No Medium-Risk Vulnerabilities**
+- **✅ Dependencies Audit Passed**
+
+### 🛠️ Security Best Practices
+
+```typescript
+// Secure server configuration
+const {router} = http({
+  errorHandler: (err: Error) => {
+    // Never expose stack traces in production
+    return Response.json({error: 'Internal server error'}, {status: 500})
+  },
+  defaultRoute: () => {
+    return Response.json({error: 'Not found'}, {status: 404})
+  },
+})
+
+// Apply security middleware stack
+router.use(
+  createCORS({
+    origin: ['https://yourdomain.com'], // Restrict origins
+    credentials: true,
+  }),
+)
+
+router.use(
+  createRateLimit({
+    windowMs: 15 * 60 * 1000, // 15 minutes
+    max: 100, // Limit each IP to 100 requests per window
+  }),
+)
+
+router.use(
+  '/api/*',
+  createJWTAuth({
+    secret: process.env.JWT_SECRET,
+    algorithms: ['HS256'],
+  }),
+)
+
+// Secure body parsing
+router.use(
+  createBodyParser({
+    json: {limit: '10mb'},
+    urlencoded: {limit: '10mb'},
+    multipart: {limit: '50mb'},
+  }),
+)
+```
+
+### 🔍 Security Monitoring
+
+0http-bun provides built-in security monitoring capabilities:
+
+```typescript
+// Security logging with request context
+router.use(
+  createLogger({
+    serializers: {
+      req: (req) => ({
+        method: req.method,
+        url: req.url,
+        ip: req.headers.get('x-forwarded-for') || 'unknown',
+        userAgent: req.headers.get('user-agent'),
+      }),
+    },
+  }),
+)
+
+// Prometheus metrics for security monitoring
+router.use(
+  createPrometheusMetrics({
+    prefix: 'http_',
+    labels: ['method', 'route', 'status_code'],
+  }),
+)
+```
+
+### 🚨 Security Recommendations
+
+1. **Environment Variables**: Store secrets in environment variables, never in code
+2. **HTTPS Only**: Always use HTTPS in production with proper TLS configuration
+3. **Input Validation**: Validate and sanitize all user inputs
+4. **Regular Updates**: Keep dependencies updated and run security audits
+5. **Monitoring**: Implement logging and monitoring for security events
+
+> 📖 **Security is a continuous process**. While 0http-bun provides strong security foundations, always follow security best practices and conduct regular security assessments for your applications.
