Abstract

In today’s globalized economy, multinational organizations face increasing challenges in ensuring secure, seamless, and efficient communication across geographically dispersed units. This paper proposes a secure hybrid network architecture designed to facilitate collaborative operations for multinational businesses. By integrating cloud-based and on-premise infrastructures, the model supports both centralized control and localized autonomy. Emphasis is placed on authentication, end-to-end encryption, secure file sharing, and real-time communication. The research also presents a prototype implementation using Firebase for authentication, a web and Android front end for access, and a secure admin panel for oversight. Findings show the system enhances productivity, reduces risk exposure, and supports compliance with international data protection standards.
