Advanced Security — Data Sovereignty Plan

Infowin Hybrid Vault

Business logic updates in the cloud; the database is deployed in your on-premises server room. Solve the 'data anxiety' of the SaaS era while maintaining both agility and sovereignty.

Architecture Overview

☁️ Cloud Logic Layer

UI / Business Logic / AI Algorithms — continuously auto-updated

🔒 System Command Flow (mTLS)

Mutual TLS encrypted tunnel — computation commands only, raw data never leaves

🌐 Personnel Access Flow (Cloudflare)

Zero Trust Tunnel — secure remote access for authorized staff (Elite)

🏠 Local Data Layer

PostgreSQL / Redis — deployed in your server room, IP never exposed

Three Security Pillars

Row-Level Security (RLS)

Even in the cloud, PostgreSQL RLS ensures absolute isolation between tenants — engineers cannot cross-read data.

Complete Audit Trail (Audit Log)

Every read, modification, and deletion is recorded with tamper-proof logs: who, when, what.

One-Click Local Deployment

Deploy local database with one Docker command. Schema auto-migrates — no manual maintenance needed.

Technical Specifications

Transport Encryption

AES-256 GCM TLS 1.3

Data Isolation

PostgreSQL RLS

Deployment

Docker One-click install script

Protocol

gRPC / REST over mTLS

Ideal for: Law firms, CPA firms, temple trusts, high-net-worth asset management
