Top 5 WAN Monitoring Software
1. Paessler PRTG
Unlike most monitoring tools, which charge per device, PRTG Network Monitor uses a sensor-based model. You pay for the metrics you actually track, making it easier to control costs as your network grows.
Key capabilities
- Sensor-Based Licensing: Licensing based on number of monitored metrics rather than devices. You control your monitoring scope and costs precisely.
- NetFlow/sFlow Analysis: Detailed traffic analysis for bandwidth and application monitoring.
- Wireless Network Monitoring: Monitors wireless access points, client connections, and RF performance beyond standard wired network monitoring.

Visit Website2- ManageEngine Site 24×7
Site24x7 runs entirely in the cloud, so you skip the server setup and maintenance. One dashboard shows your websites, apps, servers, and WAN links.
Key capabilities
- Cisco IP SLA Integration: If you use Cisco routers, Site24x7 taps into IP SLA operations to measure actual performance between your sites—latency, jitter, packet loss.
- NetFlow/sFlow Analysis: See traffic patterns to plan capacity upgrades and identify bandwidth hogs.
- Configuration Management: Automatically backs up network device configs. When something breaks, you can compare current settings to what worked yesterday.
- Linux Deployment: Runs on Linux without needing Windows Server licenses.
3- Cisco ThousandEyes
ThousandEyes focuses on problems outside your control, such as internet routing, ISP performance, and cloud provider connectivity. The platform runs from Cisco’s cloud, so there’s no hardware to deploy.
Key capabilities
- Cloud-Native SaaS: No servers to maintain. Cisco handles infrastructure and updates.
- Active Synthetic Monitoring: Agents placed in different locations continuously test your network and apps, catching issues before users report them.
- Internet Path Visualization: When your site is slow, you can see exactly where on the internet the delay occurs—your ISP, a peering point, the destination network.
- BGP Monitoring: Tracks internet routing changes. If your traffic suddenly routes through a different country, you’ll know why performance dropped.
4- Nagios XI
Nagios XI runs on Linux and monitors through plugins. The core software is simple, but thousands of plugins allow users to monitor virtually anything, from standard network gear to custom applications.
Key capabilities
- Plugin Architecture: The community has built plugins for most scenarios. If you need something specific, you can write your own in any language (Python, Bash, Perl).
What is WAN monitoring?
WAN monitoring tracks network performance across locations between offices, data centers, and cloud services. It measures bandwidth usage, latency, packet loss, and jitter to ensure applications work smoothly across distances.
Key aspects of WAN monitoring include:
- Performance Monitoring: Tracking various metrics such as bandwidth usage, latency (delay in data transmission), packet loss (data that never reaches its destination), and jitter (variance in time it takes for packets to travel). These metrics help in understanding the quality of the network connection.
- Fault Management: Detecting and diagnosing network issues to minimize downtime. This involves identifying failed devices or links, troubleshooting problems, and implementing solutions to restore connectivity.
- Configuration Management: Keeping track of network device configurations and ensuring they are optimized for performance. This can also involve updating configurations to adapt to network changes or to enhance security.
- Security Monitoring: Protecting the network from external threats such as hacking, phishing, and malware attacks. This involves monitoring for suspicious activity and ensuring that firewalls and other security measures are up to date and effective.
- Traffic Analysis: Analyzing the types of traffic flowing over the network to identify usage patterns, bandwidth hogs, and potential security threats. This can help in capacity planning and ensuring that critical applications have the necessary resources.
