Modern networks are continually changing with the popularity of Wireless environments and Bring-Your-Own-Device (BYOD) infrastructures becoming more dominant . With these evolving network types comes the challenges for network admins to keep track of their entire networks and devices within those networks.
On top of that, the variety of network-devices has also changed. Now, it is not only a desktop computer or server, but Virtual servers, Wireless APs, VoIP boxes, mobiles, switches, and even smartwatches.
Creating Inventories and documenting these types of environments can be overwhelming for any network admin. But as the network grows, the administrator will have to audit the entire network continually to stay on top of new devices and components into their networks.
Keeping track of all these devices is the key to capacity planning, troubleshooting, and security — this is where a Network Discovery Tool and Software comes in handy.
Here is our list of the fifteen best network discovery tools and software for automatically scanning and discovering network devices:

What is Network Discovery?
Network Discovery is the process, either automatically or manually, to find new devices and their interfaces.
A Network discovery tool can help find everything that is connected to a network, create topology maps, and generate reports.
These type of software scans the entire network, identify its components, and creates an inventory.
With this information, the software can create visualizations of the physical and virtual network connectivity. These tools can consolidate two essential functions, scanning a network, and mapping it automatically.
What should you look for in Network Discovery tools?
We reviewed the market for systems that offer scanning and discovery of network devices and analyzed the options based on the following criteria:
- An automated service that can scan an entire network continuously
- A system that will compile a hardware inventory including all discovered network devices
- A system that is able to spot when devices are added, moved, or removed
- An easy-to-use system that shows live device statuses in the dashboard
- A network topology mapping service
- A free trial or a system that is free to use
- A free tool or a paid system that offers value for money
With these selection criteria in mind, we have found several network scanners that can discover and log all connected network devices. We have included packages that will install on Windows and Linux and also cloud-based platforms.
Here's a List of the Best Network Discovery Tools of 2021:
SolarWinds Network Performance Monitor “NPM” is more than just a network discovery tool. It is a comprehensive multi-vendor network monitoring software, designed for medium to large-scale businesses.
NPM scans the network with its devices, end-points, and links (whether physical or logical).
The auto-discovery process creates an intelligent network map that helps you visualize graphical and contextual representations. If the network changes, such as new devices are added, moved, or removed, the maps will update automatically.
This map shows all relationships between devices which include, routers, interfaces, WAN links to remote sites, cloud-based services, wireless systems, firewalls, and a lot more.
The following screenshot shows an automated intelligent mapping, displaying many running links towards a Cisco router and a link down (colored in red).
The map shows topology connections which are the lines showing interface bandwidth, outbound traffic, and utilization in percentage.
What are some features related to network discovery and mapping?
- Wireless Heat Maps: With WiFi Monitor, an integrated tool in NPM, you can create Wireless Heat Maps that helps you visualize the signal strength and the location of clients. You can also optimize your Wifi network by troubleshooting signal overlaps and dead zone areas.
- Color-Coded Maps: The maps use different colors to help visualization. An overloaded connection is red, up and running connection is green, and warning links in yellow.
- Visualize Traffic, Performance and Configuration: NPM with the help of SolarWinds NetPath can show you a hop-by-hop traffic analysis of on-premises, cloud, or hybrid environments. NetPath can also measure performance characteristics of each node and its links.
- Correlate Network Data Across the Entire IT stack: With the integrated tool, PerfStack you can troubleshoot much faster. With PerfStack you compare different data types side-by-side in one dashboard and see data on the same timeline.
- Visualize and Monitor SDNs:NPM, with the help of Cisco ACI, lets you monitor your Software Defined Networks “SDNs.” You can keep track of your logical network, including APICs, tenants, spins, leaves, endpoint groups, etc.
Network Performance Analyzer is only supported by Windows Server 2016 and 2019.

Atera is a cloud-based infrastructure management suite that is aimed at managed service providers (MSPs). When the MSP takes on a new client, it can run the system’s autodiscovery function to get all of the new network’s connected devices logged.
As a system created for MSPs, the Atera network monitoring system is designed to connect to any network anywhere, although the remote network needs an agent program installed on it to gather data and communicated with the cloud-based system server. The package is also able to work with several networks with different ownership simultaneously.
The system dashboard doesn’t require any software to be installed because Atera is run from the cloud and users access the console through any standard browser.
During ongoing operations, the network monitoring service will keep track of device statuses while also noticing any changes to the device inventory. Any additions or removals will cause the network inventory to be automatically updated.
The Atera package includes system management tools as well as monitoring utilities. MSP technicians can use the dashboard to access remote devices and fix problems. Other management tools in the service include a patch manager and a software license management system.
Atera is a subscription service with a rate levied per technician per month. There is no requirement for a deposit and no minimum service period, which makes the service very flexible. Seats can be added and removed from an account very easily. There are three editions available: Pro, Growth, and Power. All of these versions include the autodiscovery feature.
- Pro: $79 per technician per month
- Growth: $119 per technician per month
- Power: $149 per technician per month
Download: There is no download needed to use Atera. You can access a 30-day free trial.
Syxsense Manage is an endpoint management system that is delivered from the Cloud. Although the console for the service is cloud-based and accessed through a browser, there does need to be some software installed on each monitored device. This is an agent program and it is available for Windows, macOS, and Linux.
The system will include devices into the monitoring system no matter where they are, so endpoints do not all have to be on the same network. It can include devices on different sites and also cloud resources. The process of enrolling devices is made easier by an autodiscovery procedure.
The device discovery process also requires that an agent is first installed on one endpoint connected to the network. This module then explores the network and identifies all of the other devices. When an endpoint is encountered, the system downloads an agent onto that. The discovery process is constant and it will notice if any new endpoint gets added to the system during its service life.
Once an endpoint agent is active on a device, it searches for software and reports back to the Syxsense server details about the operating system, its type, and version number. It also lists all software packages installed on the endpoint, together with their version numbers. This enables Syxsense Manage to compile a software inventory.
The software inventory provides the basis for a license management service and a patch manager. The patch manager scans software providers for notifications of updates for those packages that it has listed in its inventory. When a patch or an update is available, the Syxsense system copies over the installer package and prepares it for rollout.
The system administrator is able to define suitable times for software updates. It is also possible to specify whether patches should be applied automatically or whether approval is needed. Updates can be applied unattended and all actions are logged. The system administrator can check on the status report to see which installation events completed successfully and which encountered an error.
Price: Syxsense Manage is a subscription service. There is also a managed version of the package, which is called Syxsense Active Manage. There are no prices advertised on the Syxsense website. You have to contact Syxsense for a quote.
Download: Syxsense Manage is available for a 14-day free trial.
Network Topology Mapper, developed SolarWinds, is an advanced mapping software capable of creating automatic network maps. In contrast to Network Performance Monitor that does it all, the Topology Mapper focuses only on scanning and mapping networks.
This tool is capable of scanning and finding network devices, virtual hosts, servers, and more. From the scan results, you can build one or multiple maps and export them to Visio. Network Topology Mapper can also detect any changes in the network topology automatically and send alerts.
How to discover a network and create a map with the Network Topology Mapper?
- Enter SNMP, WMI, and VMWare credentials.
- Identify the network. You have two options, add a new subnet or a seed device (core or central device). The last option brings up subnets that are important on your network.
- Exclude certain devices.
- Schedule the network discovery process to run again anytime.
- All the nodes found will be listed in an inventory, and an interactive map will be created automatically.
The map created is interactive. You can add or remove nodes from the map, individually or as groups. The group of nodes can be labeled with roles, such as vendor, machine type, location, subnet VLAN, or unidentified.
All the nodes will be displayed as clickable icons. You can get in-depth information about the status of each node. You can also generate inventory reports with raw network data and export them into CVS.
Price: The Network Topology Mapper is cheaper than the full NPM. It starts at $1380.00 (USD), for more details on their license get a quote.

PRTG uses the concept of monitoring sensors, to keep track of all of these metrics from a single platform. The sensors are the essential monitoring elements and measure a single value in the entire network. Sensors are also used as a licensing model in PRTG.
When running PRTG for the first time, these sensors must be defined (or the software will keep defaults). After that, the software can begin a network scanning process, referred to as Auto-discovery to find a wide range of devices and their links. When the network elements are discovered and thoroughly documented, the sensors can start to monitor them.
All updated monitoring status data can be used with a “PRTG map” to create web-page reports. With the help of its customizable layouts, you can design overview pages with in-depth information and publish them.
PRTG maps can show information of all the elements on your network, including:
- The Status icons on every device.
- A quick network view for internal NOC or Intranet.
- A custom view of monitoring sensors, such as Virtualization, WAN links, Wi-Fi, Cloud, VoIP, etc.
- The map with connection lines and geographical locations.
PRTG on-premises is only compatible on Windows Servers.
Price: You can purchase PRTG through different packages based on the number of sensors and server installations. For example, PRTG500 allows 500 sensors and one server installation for $1,360 (USD) on a one-time payment including 12-month maintenance.
