This document outlines the security architecture and compliance measures implemented within the Client-Capture-Automations ecosystem.

Handling Personally Identifiable Information (PII), such as names, phone numbers, and addresses, requires a rigorous security framework.

• Database Encryption: All lead data is persisted in a Supabase (PostgreSQL) database with AES-256 encryption-at-rest.
• Row-Level Security (RLS): Supabase RLS policies ensure that dashboard users can only access the data they are authorized to see, preventing cross-tenant data leakage.
• TLS/SSL: All data in transit (API calls from Frontend to Backend) is encrypted using TLS 1.2+.

The system is built on modern, cloud-native platforms with enterprise-grade security controls.

• FastAPI & Pydantic: The backend uses strict Pydantic models for data validation, providing native protection against SQL Injection and Buffer Overflow attacks.
• Decoupled Architecture: By separating the Frontend, Backend, and Database, the platform minimizes the attack surface.
• Secure Secrets Management: All API keys (OpenAI, Twilio, Supabase) are managed via environment variables and never committed to source control.

Integrations with third-party communication providers follow industry best practices.

• E.164 Normalization: Phone numbers are normalized using the Google libphonenumber standard before processing, preventing malformed inputs from triggering unexpected logic.
• GSM-7 Sanitization: SMS payloads are sanitized to remove non-GSM-7 characters, ensuring delivery integrity across all carrier types.
• Webhook Verification: Incoming webhooks (e.g., from Twilio) are validated to ensure they originate from the trusted provider.

The system's design incorporates principles of Least Privilege and Auditing.

• Audit Logging: Every automation event (AI response, SMS sent, Email delivered) is logged in a persistent automation_logs table for debugging and compliance verification.
• Rate Limiting: The backend implements rate-limiting to protect against Denial of Service (DoS) attacks and API abuse.
