365 Architect — Enterprise Architecture

1. Enterprise Overview

365 Architect is an enterprise technology company delivering a portfolio of security, AI, and compliance products purpose-built for mid-to-large enterprises operating across regulated industries. Our mission is to provide the intelligence layer that protects, optimises, and governs enterprise AI and cloud operations — ensuring data sovereignty, regulatory compliance, and operational excellence.

1.1 Product Portfolio

1.2 Enterprise Architecture Principles

• Data Gravity Rule — sensitive data must never leave the enterprise perimeter in plaintext
• Zero-Knowledge by Default — no external service ever has access to customer plaintext
• Least-Privilege Operations — every component operates with minimum required access
• Defence in Depth — multiple independent verification layers across every boundary
• Observability by Design — every action is logged, auditable, and traceable
• No Single Point of Trust — distributed trust with MPC, dual-key, and split-secret architectures
