5 Leading Network Monitoring System Providers Every IT Professional Should Know

A warehouse might lose access to its order platform for a few minutes. The cloud application is healthy. The firewall also shows no obvious fault. The internet provider reports normal service. 

Eventually, an administrator traces the delay to packet loss on one branch connection. But they have to check four consoles and call two vendors.

A network monitoring system shortens that search. It monitors the following aspects:

Then, it helps IT staff distinguish a failing switch from a slow SaaS service. It might also be a congested ISP route. Security matters here as well. It could be an unexpected device, an altered route, or a burst of outbound traffic. These may signal more than poor performance.

The best providers take different approaches. Some concentrate on traditional network infrastructure. Others view the network through users, security controls, or managed service operations.

1. Fortinet FortiMonitor

FortiMonitor is a SaaS-based platform. It monitors the following aspects:

• Endpoints
• Network devices
• Infrastructure
• Applications
• Cloud services. 

Basically, it includes the following features:

Fortinet Security Fabric environments get more. In this case, it displays device statistics and FortiLink status. It also shows interface utilization, Wi-Fi radio use, and SD-WAN underlay performance.

That scope makes FortiMonitor a plausible network monitoring system for IT infrastructure. It spans branch offices, remote workers, data centers, and public cloud resources. 

Path analysis tracks packet loss, delay, jitter, DNS resolution, and round-trip time. It also tracks other measurements from different vantage points. This helps the team determine the status of the sluggish application.

2. Zscaler Digital Experience

Zscaler Digital Experience (ZDX) monitors performance from user devices to SaaS applications, private applications, and internet services. It measures device health, Wi-Fi quality, network paths, ISP performance, and application response while using synthetic probes to test services from actual endpoints.

ZDX differs from a conventional SNMP-centered tool. It focuses on the employee’s digital experience. This suits organizations where people work from home, branches, hotels, and customer sites. 

For instance, a centralized polling server may show that Salesforce is reachable. But the user may still struggle with weak Wi-Fi. It might also be a strained laptop or an erratic last-mile connection.

The platform provides hop-by-hop visualization. It also collects endpoint measurements such as –

• CPU use
• Memory consumption
• Disk activity
• Network I/O
• Wi-Fi signal strength. 

It sends threshold-based alerts. It also sends notifications to IT service management tools through webhooks. However, ZDX may complement rather than replace deeper switch, router, and data-center monitoring.

3. Sophos

Sophos approaches monitoring through network security. Its portfolio brings the following into centrally managed services:

• Firewalls
• Switches
• Wireless access points
• Network detection and response
• SD-WAN devices
• Remote-access controls. 

Sophos NDR watches network activity for suspicious behavior. It does so across managed, unmanaged, and agentless assets (including hybrid environments).

This distinction matters. Sophos becomes more interesting when the monitoring objective includes –

Traditional availability checks might miss those aspects.

What problem are you actually trying to catch? 

If the answer is “an overloaded link,” a performance-first tool may be a better fit. If it’s “a device communicating strangely after an account compromise,” Sophos NDR has the more relevant lens.

Sophos switches support SNMP configuration, including SNMPv3 authentication and encryption, while Sophos Firewall includes live connections, VPN status, packet capture, logs, diagnostics, and network reports. Yet buyers should treat those functions as parts of a security platform, rather than assuming they equal a full multi-vendor network operations suite.

4. Barracuda RMM

Barracuda RMM is built mainly for managed service providers supervising multiple customer environments. It combines the following functions in one dashboard:

That service-provider orientation is excessive for an internal IT department. But an MSP might manage fifty small businesses. They must separate policies and recurring reports.

Network service monitors can –

• Check TCP or UDP port availability
• Collect information about the device or server behind a service
• Measure round-trip time. 

Barracuda’s documentation warns that monitoring more than 100 network services through one Onsite Manager may reduce performance, in which case you may need another manager. Static IP dependence is another wrinkle because monitoring stops after an address change until you reapply the monitor.

5. SolarWinds Network Performance Monitor

SolarWinds Network Performance Monitor discovers –

• Multi-vendor routers
• Switches
• Firewalls
• Wireless controllers
• Interfaces.

Then, it tracks the following:

NetPath displays hop-by-hop routes across on-premises and cloud infrastructure. Meanwhile, PerfStack places network, system, and application measurements on a shared timeline. This exposes a connection between an interface spike and an application slowdown. 

Moreover, historical baselines, dependency-aware alerts, and capacity forecasting help teams a lot. They reduce noise and spot saturated links.

The self-hosted model gives administrators substantial control. But it brings servers, database care, upgrades, polling design, and permission management. 

Top Network Monitoring System Providers

Before selecting a platform, run a trial across –

Disconnect a monitored interface. Degrade a WAN link. Stop a connector and check whether the platform reports its own blindness. Also, alert quality deserves equal attention. 

Fit the Monitoring Model to the Failure You Fear

No network monitoring system sees everything equally well. 

The sensible choice depends on where outages hide in your environment. It also depends on who receives the alert afterward. So, test the network monitoring system against real routes, devices, staffing limits, and escalation procedures.
