Security & Privacy¶

ReputeAPI is built with security and privacy as core principles. We understand that email security validation often involves sensitive domain information, and we've designed our platform to protect your data while providing powerful analysis capabilities.

🔒 Data Privacy Principles¶

Zero Data Retention Policy¶

We don't store your DNS queries or domain information.

✅ No query logging - DNS lookups are processed and discarded
✅ No domain tracking - We don't build profiles of your validated domains
✅ No data sharing - Your validation data is never shared with third parties
✅ Minimal metadata - Only API usage statistics for billing purposes

What We Do Store¶

Data Type	Retention	Purpose
API Keys	Until deleted	Authentication
Usage Metrics	90 days	Billing and rate limiting
Error Logs	30 days	System monitoring (no domain data)
Account Info	Until account deletion	User management

What We Don't Store¶

❌ DNS query results
❌ Domain validation history
❌ SPF/DKIM/DMARC record contents
❌ IP addresses of validated domains
❌ Email addresses from DMARC records

🛡️ Security Architecture¶

API Security¶

Authentication & Authorization¶

Request ────▶ TLS 1.3 ────▶ API Key ────▶ Rate Limit ────▶ Processing
               │             │             │
               ▼             ▼             ▼

Key Management: Hardware Security Modules (HSM) for key storage
Certificate Management: Automated certificate rotation

Access Control¶

Principle of least privilege for all system accounts
Multi-factor authentication for administrative access
Role-based access control (RBAC) for team permissions
Regular access reviews and automated deprovisioning

📋 Compliance Standards¶

🚨 Security Best Practices¶

API Key Management¶

# Generate a new API key
curl -X POST "https://api.reputeapi.com/auth/keys" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -d '{"name": "Production App", "permissions": ["read"]}'

# Rotate keys regularly
curl -X PUT "https://api.reputeapi.com/auth/keys/KEY_ID/rotate" \
  -H "Authorization: Bearer YOUR_TOKEN"

Secure Integration¶

✅ Do: - Store API keys in environment variables or secret managers - Use HTTPS for all API communications - Implement retry logic with exponential backoff - Monitor API usage for anomalies

❌ Don't: - Hardcode API keys in source code - Log API keys or responses containing sensitive data - Use API keys in client-side JavaScript - Share API keys between environments

Rate Limiting Best Practices¶

import time
import requests
from tenacity import retry, stop_after_attempt, wait_exponential

@retry(stop=stop_after_attempt(3), wait=wait_exponential(multiplier=1, min=4, max=10))
def validate_domain(domain, api_key):
    response = requests.post(
        'https://api.reputeapi.com/v1/check',
        headers={'Authorization': f'Bearer {api_key}'},
        json={'domain': domain}
    )

    if response.status_code == 429:  # Rate limited
        retry_after = int(response.headers.get('Retry-After', 60))
        time.sleep(retry_after)
        raise Exception("Rate limited")

    return response.json()
