UBU Office is a powerful web based file sharing and collaboration platform designed by Kastech to simplify how individuals and organizations manage, store, and exchange information. The system supports secure online document sharing, permission control, guest file requests, and advanced document management. It serves as a complete digital workspace that enhances productivity, ensures compliance, and supports team collaboration across multiple devices.
The Challenge
Before UBU Office was developed, many organizations relied on fragmented third party services for document sharing, leading to issues with security, control, and accessibility. These solutions often lacked proper permission management, metadata organization, and integration with enterprise tools.
Kastech was tasked with creating a unified and secure file sharing application that offered enterprise level performance, strong compliance, and advanced collaboration capabilities. The platform also needed to support mobile devices, versioning, conversion, and multi format editing, while remaining easy to use for both registered and guest users.
