Why Do I Need a LAN Monitoring Tool?

There are many reasons why LAN monitoring tools are important to enterprises. The most significant reason is that they provide you with complete visibility of your connected devices. With a LAN monitoring tool, you can view the performance of devices and your network through one pane of glass.

Typically, you’ll be able to view a dashboard of your network’s performance showing which devices are experiencing difficulties. The top-down perspective given to you by a LAN monitoring tool helps to spot the signs of performance degradation and cyberattacks before your service is disrupted.

The best LAN monitoring tools typically offer the following features:

• Real-time and historic network and hardware monitoring
• Autodiscovery to automatically configure devices
• Customizable alerts and notifications to highlight emerging security events
• Visualization and graphs to show network changes

For larger networks, LAN monitoring tools are essential because they can monitor hundreds of devices.
