Published: June 4, 2025

Mapping your computer network is essential for managing and securing your IT system.

Doing it manually for a large, complex network is a mammoth task. That's why you absolutely need good network mapping software.

👉 We tell you how to choose it, and present the 5 best network mapping software on the market.

What is network mapping?

Network mapping gives you a snapshot at a given moment in time of all the interconnections in your network (peripherals, servers, ports, racks, cables, mobile elements, virtual domains, etc.).

There are 3 types of network card:

  • Physical maps : show all network components, right down to ports and sockets.
  • Logical maps: these show the network typology (bus, ring, tree, etc.) and data flows between physical elements.
  • Functional maps: reproduce application traffic.

In addition to monitoring your network, network mapping enables you to troubleshoot network problems by identifying bottlenecks and unauthorized access, as well as obtaining network performance indicators .

Our 7 tips to suit your needs

You've decided to make the switch from manual mapping to automatic mapping. But to be really useful, the tool you choose must have the following features:

Criteria 1: a network scanner

Managing IP addresses is clearly one of the most complex tasks for a network administrator. If your software has to offer just one feature, this is it.

👉 The automatic scanner will enable you to obtain a list of devices connected to your computer network. The tool is also very useful when you've lost the IP address of a host or piece of equipment.

Criteria 2: An automation function for periodic scanning

The more complex your network, the more difficult it is for your teams to manage. Automating periodic mapping is therefore a guarantee of efficiency and reliability.

👉 What's more, manually programming a scanner is a low-value-added process; you might as well delegate it to software. Your mapping software must therefore absolutely include an automation function.

Criterion 3: ease of use

This may seem like a secondary criterion, but it's actually essential. Mapping software must be easy to use. The application must be there to save you time, so you can get on with more important tasks.

👉 It's out of the question to spend hours deciphering a diagram or trying to figure out how to program a network scan. Let's face it, good mapping software has to be ergonomic.

Criterion 4: a network mapper

Mapping a network drive gives you access to files and applications on another computer in the network. By mapping it, you'll never have to look for it again.

👉This function is useful if you have shared needs in your company. It gives all employees access to the same resources.

Criteria 5: Intuitive customization

To save time and resources, the software must be usable by all members of the IT department, regardless of when they joined the company. It must also be usable without extensive training by the software publisher.

Criterion 6: Responsive helpdesk support

This criterion complements the previous one. Again with a view to optimization, it is important to be able to contact the software publisher's support service at any time .

👉 It's best to opt for 24/7 technical support. You should also check the software publisher's commitment to response times. It would be a shame to pay for 24/7 support and have to wait several hours for a response.

Criterion 7: An effective monitoring and alerting tool

Organizations can no longer afford to have their IT network blocked. Business interruption can be very costly.

👉Your network mapping software must include a monitoring and alert system. This will enable you to anticipate problems, diagnose them quickly and take action in good time.

How does network mapping work?

Network mapping is based on a simple principle: visualize the invisible. It scans your infrastructure to detect all connected equipment such as servers, routers, switches, workstations, printers and so on. Then, it displays them in the form of a dynamic diagram, like an interactive map.

Behind this apparent simplicity lie several technical building blocks:

  • automatic scanning (often via SNMP, ICMP, WMI or SSH) to identify active devices ;

  • analysis of the relationships between these devices (who talks to whom, via which ports, using which protocols);

  • visual modeling: nodes and links are organized according to their role, location or criticality level;

  • real-time updating: some tools monitor changes (new devices, breakdowns, saturation, etc.) and update the map continuously.

This process not only gains visibility, but also prevents incidents,optimizes network performance and enhances security.

📌 Example of network mapping:

Network mapping software at a glance

  • Network mapping software is indispensable for all companies, whatever their size.
  • The tool enables interconnections to be analyzed, problems to be detected in good time, and the computer system to be troubleshooted quickly to avoid any loss of operations or important information.
  • There are many different mapping software packages on the market. To make a choice, it is necessary to use simple criteria. The software must include several functionalities, including a scanner, a mapper, an alert system and automated checks. The publisher must offer technical support. Finally, the software must be easy to use.
