Infrastructure Security

1. Overview

ProtoVoice infrastructure is built on enterprise-grade cloud platforms with security, reliability, and performance as foundational principles. Our infrastructure supports real-time AI voice processing at scale while maintaining the highest standards of data protection and availability.

2. Cloud Infrastructure

• Primary Infrastructure: Amazon Web Services (AWS) and Google Cloud Platform (GCP).
• Both providers maintain SOC 2, ISO 27001, and numerous other security certifications.
• We leverage provider security features including VPCs, security groups, and IAM.
• Infrastructure as Code (IaC) ensures consistent, auditable deployments.
• Multi-cloud architecture provides resilience and avoids vendor lock-in.

3. Architecture Design

• Microservices: Loosely coupled services for scalability and fault isolation.
• Containerization: Docker containers orchestrated with Kubernetes for consistent deployments.
• API Gateway: Centralized authentication, rate limiting, and request routing.
• Service Mesh: Secure service-to-service communication with mutual TLS.
• Event-Driven: Asynchronous processing for high throughput and resilience.

4. Geographic Redundancy

• Multi-Region Deployment: Active infrastructure in US-East (Virginia) and US-West (Oregon).
• Data Replication: Synchronous replication between regions for critical data.
• Failover Capability: Automatic failover to secondary region within minutes.
• Edge Locations: Content delivery and DDoS protection through global edge network.
• Latency Optimization: Traffic routed to nearest healthy region for optimal performance.

5. Network Security

• Firewalls: Network and application-layer firewalls protecting all entry points.
• Web Application Firewall (WAF): Protection against OWASP Top 10 and custom rules.
• DDoS Protection: Enterprise-grade DDoS mitigation with automatic scaling.
• Network Segmentation: Isolated network segments for different security zones.
• Private Connectivity: VPC peering and private links for secure integrations.
• Intrusion Detection: Network-based intrusion detection and prevention systems.

6. Data Encryption

• Encryption at Rest: AES-256 encryption for all stored data, including databases and file storage.
• Encryption in Transit: TLS 1.3 for all external communications; mutual TLS for internal services.
• Key Management: Hardware Security Modules (HSMs) for cryptographic key storage.
• Key Rotation: Automated key rotation on regular schedules.
• Certificate Management: Automated certificate provisioning and renewal.

7. Access Control

• Zero Trust: No implicit trust based on network location; verify every request.
• Identity Management: Centralized identity provider with SSO and MFA.
• Role-Based Access: Granular permissions based on job function and least privilege.
• Just-in-Time Access: Privileged access granted temporarily with approval workflow.
• Access Reviews: Quarterly access reviews for all systems and data.
• Audit Logging: Comprehensive logging of all access and administrative actions.

8. Availability & Reliability

• SLA: 99.9% uptime guarantee for production services.
• Load Balancing: Multi-layer load balancing for high availability.
• Auto-Scaling: Automatic capacity adjustment based on demand.
• Health Monitoring: Continuous health checks with automatic recovery.
• Chaos Engineering: Regular failure injection testing to validate resilience.
• Status Page: Real-time service status at status.protovoice.ai.

9. Backup & Disaster Recovery

• Automated Backups: Daily full backups with point-in-time recovery.
• Backup Encryption: All backups encrypted with customer-specific keys where applicable.
• Geographic Distribution: Backups stored in multiple geographic locations.
• Recovery Testing: Monthly disaster recovery drills and documentation.
• RTO: Recovery Time Objective of 4 hours for critical services.
• RPO: Recovery Point Objective of 1 hour for transactional data.

10. Monitoring & Observability

• Real-Time Monitoring: 24/7 monitoring of all systems and services.
• Metrics Collection: Comprehensive metrics from infrastructure and applications.
• Distributed Tracing: End-to-end request tracing for performance analysis.
• Log Aggregation: Centralized logging with retention and analysis capabilities.
• Alerting: Intelligent alerting with escalation procedures.
• Dashboards: Real-time operational dashboards for visibility.

11. Security Operations

• Security Monitoring: 24/7 security monitoring and threat detection.
• SIEM: Security Information and Event Management for correlation and analysis.
• Vulnerability Scanning: Continuous automated vulnerability scanning.
• Penetration Testing: Annual third-party penetration testing.
• Bug Bounty: Responsible disclosure program for security researchers.
• Incident Response: Documented procedures with regular tabletop exercises.

12. Change Management

• CI/CD Pipeline: Automated testing and deployment with approval gates.
• Code Review: All changes require peer review before merging.
• Staged Rollouts: Progressive deployment with automatic rollback capability.
• Change Windows: Scheduled maintenance windows with customer notification.
• Rollback Procedures: Documented and tested rollback for all deployments.
• Post-Deployment Verification: Automated testing after every deployment.

13. Compliance & Certifications

• SOC 2 Type II: Annual audit covering security, availability, and confidentiality.
• HIPAA: Compliant infrastructure for healthcare customers with BAA.
• PCI DSS: Payment processing through certified partners.
• GDPR: Data protection measures for European data subjects.
• CCPA: California consumer privacy compliance.
• ISO 27001: Information security management (cloud provider level).

14. Physical Security

Our cloud providers maintain world-class physical security at their data centers, including 24/7 security staff, biometric access controls, video surveillance, and environmental controls. Data centers are SOC 2 and ISO 27001 certified. ProtoVoice corporate offices implement physical access controls, visitor management, and clean desk policies.
