9 Best Network Discovery Tools

By SolarWinds on April 8, 2021


Your organization’s network is large, complicated, and constantly expanding. While you might think you have a handle on it, manually monitoring your network can lead to inaccuracies due to outdated data, undetected devices, and other common visibility issues. A network device discovery tool can help you find devices on a network to manage your device’s health, troubleshoot performance problems, and prepare for your network’s future.

In this article, I’ll list some excellent network discovery software, starting with three SolarWinds® network device discovery tools. Although they take different approaches, both Network Topology Mapper (NTM) and ipMonitor® enable you to discover devices for improved visibility and insight. The more comprehensive Network Performance Monitor (NPM) is designed to automatically scan your network for devices and various metrics, analyze the data, and notify you of important updates.

 

 

Finding the Right Network Device Discovery Software

Network device discovery tools enable you to automatically discover exactly what devices are on your network at any given time, which helps you keep your network’s devices organized, ensure they’re working well, and get informed when issues arise. Great network discovery tools can also help you easily troubleshoot performance problems that would otherwise be tedious to tackle, helping designate your time to what’s important.

Here are some benefits of using network discovery software:

Continuously Monitor Your Network

By constantly observing your network and watching for changes, a network discovery tool can help you detect and resolve issues quickly. Not only will this prevent smaller problems from expanding into cost-draining crises, but also keep you informed about your network’s general health and performance.

Locate Ports and IP Addresses

Network discovery tools allow you to find all IP addresses on your network to ensure each one is unique and valid, safe from misuse, and not out-of-use or otherwise compromised. You can also uncover information about your ports, helping you stay on top of data flow and speed. Open ports could yield security breaches, and some network discovery tools can double-check that open ports shouldn’t be closed or in stealth mode.

Automatically Discover Devices

Given the size and scalability of networks today, it can be difficult to manually keep your data up to date. Luckily, many network discovery tools can schedule autonomous rescans of your network, a process that discovers changes in your network and alerts you automatically.

Reduce Repetitive Tasks

Because network discovery software can keep your network visualizations automatically updated, you’re saved from doing the tedious labor-intensive tasks required to accurately track and find devices on your network.

Get a Glimpse and Dive Deep Into Data

Network device discovery tools are designed to collect crucial information about your network, providing you with in-depth analysis alongside network overviews. The best network discovery software options have a centralized network discovery platform, allowing you to access all crucial data and tools in one place.

Connect the Dots in Your Network

Network device discovery tools are designed to figure out how your network’s systems connect to one another, and from there determine in which form or topology they are arranged. This enables you to ensure all necessary connections are present, determine bottlenecks, and reroute outages.

All these tools are vital for surveilling your network and ensuring its devices are accounted for, organized logically, and reach optimal performance standards.
