Security & Compliance

Cloakr.ai provides enterprise-grade security and compliance features to protect your data and meet regulatory requirements.

Encryption

End-to-End Encryption

Cloakr.ai uses AES-256-GCM encryption for all data in transit and at rest:

// Client-side encryption
const encryptedData = client.encrypt("sensitive data");
const response = await client.chat({
  model: 'gpt-4o',
  prompt: encryptedData
});

Key Management

AWS KMS Integration

import { CloakrClient, KMSConfig } from '@cloakrai/sdk';

const kmsConfig = new KMSConfig({
  region: 'us-east-1',
  keyId: 'arn:aws:kms:us-east-1:123456789012:key/abcd1234-ef56-7890-abcd-ef1234567890',
  alias: 'cloakr-encryption-key'
});

const client = new CloakrClient({
  apiKey: process.env.CLOAKR_API_KEY,
  encryption: kmsConfig
});

Customer-Managed Keys (BYOK)

const client = new CloakrClient({
  apiKey: process.env.CLOAKR_API_KEY,
  encryption: {
    keyId: process.env.CLOAKR_KEY_ID,
    keyMaterial: process.env.CLOAKR_ENCRYPTION_KEY,
    rotation: true
  }
});

Key Lifecycle

1. Key Generation: Cryptographically secure random generation
2. Key Storage: Hardware Security Modules (HSMs) for key storage
3. Key Rotation: Automatic rotation every 90 days
4. Key Destruction: Secure deletion when no longer needed

PII Protection

Automatic Detection

Cloakr.ai automatically detects and redacts sensitive information:

• Personal Identifiers: Names, SSNs, driver's licenses
• Contact Information: Email addresses, phone numbers
• Financial Data: Credit card numbers, bank accounts
• Medical Information: Health records, insurance numbers
• Custom Patterns: Company-specific identifiers

Hybrid Detection Engine

// NER-based detection
const nerDetector = new NERDetector({
  models: ['en_core_web_sm', 'en_core_web_lg'],
  confidence: 0.8
});

// Regex-based detection
const regexDetector = new RegexDetector({
  patterns: [
    /SSN:\s*\d{3}-\d{2}-\d{4}/g,
    /Credit Card:\s*\d{4}-\d{4}-\d{4}-\d{4}/g
  ]
});

// Combined detection
const piiEngine = new PIIEngine({
  detectors: [nerDetector, regexDetector],
  redactionMode: 'replace'
});

Custom Redaction Rules

const customRules = [
  {
    type: 'custom_pattern',
    pattern: /CUSTOMER-\d{6}/g,
    replacement: '[REDACTED_CUSTOMER_ID]'
  },
  {
    type: 'email',
    domains: ['internal.com', 'test.com'],
    replacement: '[REDACTED_EMAIL]'
  },
  {
    type: 'phone',
    countryCode: 'US',
    replacement: '[REDACTED_PHONE]'
  }
];

client.setPIIRedactor(new PIIRedactor({ rules: customRules }));

Data Residency

Cloakr.ai supports multiple regions for data residency compliance:

Region	Location	Compliance	Use Case
US East	N. Virginia	SOC 2, HIPAA	Default region
US West	Oregon	SOC 2, HIPAA	West Coast optimization

Security Best Practices

API Key Management

// Rotate API keys regularly
const newKey = await client.rotateApiKey({
  currentKey: process.env.CLOAKR_API_KEY,
  expirationDays: 90
});

// Use least privilege principle
const restrictedKey = await client.createApiKey({
  permissions: ['chat:read', 'models:read'],
  expiresAt: '2024-12-31'
});

Data Classification

// Classify data sensitivity
const classification = await client.classifyData({
  content: "Patient medical record for John Doe",
  classification: "PHI"
});

// Apply appropriate controls
const secureClient = new CloakrClient({
  apiKey: process.env.CLOAKR_API_KEY,
  dataClassification: classification.level,
  controls: classification.requiredControls
});

Monitoring and Alerting

// Set up security monitoring
client.on('suspicious_activity', async (activity) => {
  console.log('Suspicious activity detected:', activity);
  
  // Send alert
  await sendSecurityAlert(activity);
  
  // Block if necessary
  if (activity.severity === 'high') {
    await client.blockUser(activity.userId);
  }
});
