Security & Compliance

Comprehensive security measures, compliance frameworks, and data protection policies implemented in FlowCampaign to ensure safe and legal email campaign management.

Security Architecture

Multi-Layer Security Model

1. Infrastructure Security

• Cloudflare Edge Network: DDoS protection, WAF, rate limiting
• Zero Trust Architecture: Verify every request
• Network Segmentation: Isolate different components
• DDoS Protection: Automatic mitigation at edge

2. Application Security

• Input Validation: All user inputs sanitized and validated
• Output Encoding: Prevent XSS attacks
• SQL Injection Prevention: Parameterized queries only
• CSRF Protection: Token-based request validation
• CSP Headers: Content Security Policy enforcement

3. Data Security

• Encryption at Rest: AES-256 for sensitive data
• Encryption in Transit: TLS 1.3 for all connections
• Key Management: Secure key storage and rotation
• Data Masking: Sensitive data obscured in logs
• Secure Deletion: Cryptographic data destruction

Authentication & Authorization

Multi-Factor Authentication (MFA)

Supported MFA Methods

1. TOTP (Time-based One-Time Password)

   • Compatible with Google Authenticator, Authy, etc.
   • 30-second rotation period
   • Backup codes generation

2. Email-based Verification

   • Secondary email confirmation
   • One-time codes for sensitive operations
