    emails_per_second = len(test_emails) / total_time
    
    print(f"Processed {len(test_emails)} emails in {total_time:.2f} seconds")
    print(f"Rate: {emails_per_second:.1f} emails/second")
    
    valid_count = sum(1 for r in results if r.is_valid)
    print(f"Valid emails: {valid_count}/{len(test_emails)} ({valid_count/len(test_emails):.1%})")

asyncio.run(benchmark_validation())

🛡️ Security Considerations

Data Protection

• No Data Retention: Email addresses are not stored unless explicitly configured
• Encrypted Communication: All API calls use HTTPS/TLS
• Memory Security: Sensitive data cleared from memory after use
• Audit Trails: Comprehensive logging for compliance requirements

Privacy Compliance

• GDPR Ready: Data processing transparency and user rights
• Minimal Data Collection: Only necessary data is processed
• Right to Erasure: Data can be deleted on request
• Data Portability: Export functionality for user data

Rate Limiting & Abuse Prevention

from pyidverify.email_verification import EnhancedEmailValidator

# Configure rate limiting
validator = EnhancedEmailValidator()

# Built-in rate limiting prevents abuse
try:
    results = []
    for email in large_email_list:
        result = await validator.validate_email(email)
        results.append(result)
except RateLimitExceeded:
    print("Rate limit exceeded. Please wait before continuing.")
