Executive Overview
A national revenue authority in the GCC appointed Diyar United Company to operate and maintain the network infrastructure of its headquarters building and to deliver a technology refresh across the core, edge and wireless environments. The five-year engagement combined a full infrastructure modernization with layered security enhancement, application delivery, endpoint management and training, giving the authority a modern, supported and operationally ready platform.
Client Profile
The client is a national authority in the GCC responsible for revenue administration and the delivery of related public services to individuals and businesses.
Its headquarters is the operational centre of these services, and the availability of its network, security and application infrastructure directly determines the continuity of public-facing and internal operations.
Business Challenge
The authority needed to modernize and operate a complete infrastructure estate under one accountable arrangement:
- Core and edge switching and the wireless environment required renewal to sustain performance and remain under vendor support.
- Security controls needed strengthening across multiple layers rather than at the perimeter alone.
- Application availability, endpoint management and internal operational readiness needed to be addressed alongside the infrastructure itself.
Diyar’s Solution
Diyar United delivered the modernization and assumed responsibility for operating and maintaining the environment over the full term.
Core, Edge and Wireless Refresh
Diyar delivered Cisco renewals and a technology refresh across core and edge switches and the wireless environment, restoring full vendor support and modernizing the performance baseline of the building.
Layered Security Enhancement
Security was strengthened through next-generation firewall platforms deployed across multiple network layers, replacing single-tier protection with a defense-in-depth posture.
Application Delivery and Availability
An F5 application delivery solution was implemented to improve the availability, performance and resilience of the authority’s applications.
Endpoint Management and Enablement
ManageEngine Endpoint Central Enterprise was deployed for centralized endpoint management, and training services were delivered to build internal operational readiness across the environment.
Results & Business Impact
The engagement delivered a modernized and continuously supported infrastructure:
Modernized Network Estate
Core, edge and wireless platforms refreshed and returned to full vendor support.
Defence in Depth
Layered firewall protection replaces single-tier perimeter security.
Higher Application Availability
Application delivery controls improve resilience and performance for end users.
Operational Continuity
A five-year operations and maintenance commitment keeps the building running under one accountable partner.
Strategic Value Delivered
The engagement demonstrates Diyar United’s ability to combine modernization with long-term operational ownership. Rather than delivering a refresh and departing, Diyar carries responsibility for the environment across a five-year horizon, covering network, security, application delivery, endpoint management and the training required for the authority’s own teams to operate confidently alongside it.
