# Network Management System Manage your physical, virtual and hybrid networks effectively with OpManager. Many businesses today, especially those operating in the IT landscape, deploy large-scale networks to meet their growing business requirements. This is why efficient [network management](https://www.manageengine.com/network-monitoring/tech-topics/what-is-network-management.html?nw-mgt-system) is vital for a business to ensure continuous service delivery, maintain operational continuity, and facilitate internal and external communication. However, technological advancements have enabled networks to evolve in unimaginable ways. Modern networks house a deluge of physical and virtual components comprised of parts from multiple vendors and are distributed over geographies, making network management a tall order for administrators. To work around these obstacles, businesses need a robust **network management system (NMS)** that is capable of managing physical (wired and wireless), virtual, and hybrid networks. Such comprehensive [network monitoring tools](https://www.manageengine.com/network-monitoring/network-monitoring-tools.html?nms), [network management solutions](https://www.manageengine.com/network-monitoring/network-management.html?nms) /network management systems empower network administrators and help them gain complete visibility and control over their network infrastructure. ## What are the challenges in the absence of a network management system (NMS) Below are some of the most prominent roadblocks that a business faces without a network management system: **Fault Diagnosis:** Network components are susceptible to performance degradation. Without a network management system, it's difficult to diagnose network faults, which impedes [troubleshooting](https://www.manageengine.com/network-monitoring/troubleshooting-network-issues.html?nms). **Unforeseen downtime:** Businesses can expect frequent outages and prolonged downtime without a network management system. This can adversely impact operational continuity and productivity levels. On top of this, not all businesses possess enough resources to bear the exorbitant costs of network downtime. **Service interruptions:** Without a network management system to keep networks in check, businesses may experience disruptions in service delivery, which will make it hard to meet SLAs. **Security threats:** Erroneous network configuration changes and poor network security can expose networks to security vulnerabilities, leading to data appropriation. ## OpManager: The network management system your business needs ManageEngine's reliable [network monitoring solution](https://www.manageengine.com/network-monitoring/?nms) - OpManager, is a comprehensive [network performance monitoring](https://www.manageengine.com/network-monitoring/network-performance-monitoring.html?nms) system with which organizations can gain complete visibility and control over their entire IT infrastructure.
