Managerial Role of Network Infrastructure, Cybersecurity Tools, and Systems Monitoring in Enhancing IT Service Reliability: A Case Study of GBM Abu Dhabi, UAE

This study examines the managerial impact of network infrastructure robustness, cybersecurity tool integration, and proactive systems monitoring on the overall reliability and performance of IT services within enterprise environments. The objective is to analyze how the structured deployment of advanced routing and switching technologies, security systems, and monitoring platforms contributes to IT service continuity and operational excellence at GBM – Abu Dhabi, a leading technology provider in the UAE. Using a mixed-method approach, data were collected from 35 network engineers, IT managers, and system administrators through surveys and interviews. The findings indicate that strategic management of firewalls, VPN solutions, and access control mechanisms (e.g., Cisco ISE, Forti-Authenticator) significantly reduces vulnerability exposure and strengthens endpoint defense. Efficient use of monitoring tools such as PRTG, Riverbed, and Cisco Prime enhances visibility, allowing faster incident detection and resolution. Furthermore, the integration of high-availability protocols, load balancing, and wireless scalability contributes to improved service delivery. The study emphasizes that managerial oversight, continuous documentation (e.g., ISO Smart Inventory), and cross-vendor skill development are crucial for sustaining performance in complex IT ecosystems.
