Best Network Diagram Tools

Throughout the last decade, Network Diagram tools have gone from an accessory to a crucial part of any modern administrative toolkit. As IT infrastructure gets more and more complicated, being able to properly map and make diagrams of a network becomes more and more important.

In an organization functioning without fully understanding all of its networks will find that its systems fail much easier, and malfunctions become more common. Getting a clear representation for every device in your network, as well as all of their relationships with each other is crucial for getting to grips with all of your equipment monitoring jobs.

Here’s our list of the top of the best network diagram tools:

  1. SolarWinds Network Topology Mapper – FREE TRIAL By far the best network diagram tool. Made by a reputed company in the network security industry, SolarWinds boasts not only extremely efficient performance and excellent network overview, but it also does all this through a clever and slick UI.
  2. Paessler PRTG Network Mapping Tools – FREE TRIAL A variety of network monitoring tools in one. The mapping function is part of a wider network of systems, and it’ll run on Windows Servers.
  3. ManageEngine OpManager An all-around network performance monitor that comes with an excellent automatic discovery and mapping system.
  4. ConceptDraw Pro An excellent network diagram solution for small and medium businesses.
  5. LucidChart Graphical design package that comes with some network topology maps.
  6. CADE A basic and free chart editor software with an IT icon library
  7. Network Notepad A free graphic design editor especially made in order to support creating network diagrams.

Tools that provide you with a stellar diagram of all of your network can provide you with lots of valuable information about its technical infrastructure. Later on, this helps your processes become more efficient, and streamlines troubleshooting. Reacting to issues that might pop up regarding integrity well can be a Herculean task unless you’ve got an in-depth overview of your network map.

Having an understanding of where every piece of hardware fits in within your network helps you address issues when they happen. Furthermore, it helps maintain a targeted and efficient cybersecurity approach, making sure that all of the systems on your network are systematically protected. Usually, this is done by finding malfunctioning hardware or working on your network optimization.

What Is Network Mapping?

Network mapping, like its name implies, is the process of representing your network in a visual manner within its local IT environment. It’ll include sections like the location of all of your routers, VLANs, firewalls, hosts, access points, switches, laptops, computers, and more. You can use the resulting map as essentially a schematic that guides you throughout your network.

Now, can you draw a network map by hand? Sure, but you could do it much in the same vein that a programmer could write in binary by hand. It’s far more complicated and time-consuming than it is to automate it. Not only does this minimize the chances of having a faulty map, it works faster, and can be easily scaled to accommodate the businesses’ needs. It’s worth noting that most network monitoring toolkits worth their salt feature a network mapping tool within them.

How will having a Network Diagram tool help me?

The biggest perk of using a network diagram tool as a network admin is to become more efficient. Making a diagram of a network without using a tool for it is a complex and time-consuming job. In a growing business, by the time you’ve done mapping by hand, the network has already changed and you’ve got to do it again.

Since the infrastructure of most large companies is changing constantly, a network diagram tool helps you keep up with every change in the network’s infrastructure and lets you have a bird’s eye view of all of its components.

Let’s take, for example, the number 1 entry on this list- SolarWinds Network Topology Mapper. The tool is cram-packed with a variety of features to make network diagrams absolutely flawless. It’ll automatically discover all of your network’s devices, charting them on a map immediately. You can then use this map as your guide, or even use it for FIPS-142 and PCI compliance.

Since topology has such a huge impact on your network’s performance, it’s no wonder many of the leading tech giants of today have been investing in it. Let’s take, for example, a single data packet. The longer it takes for it to get from A to B on your network, the more time it’ll take for devices to communicate, and the slower your network will be.

Below you can see some essential features that any network diagram tool needs to have in order to get on top of this list:

  • Automatic Discovery If you need to manually enter your network’s devices into a network mapping tool, then it is already performing sub-optimally. This takes a lot of time which would be better spent actually improving your network.
  • Troubleshooting Capabilities You’ll need to have a comprehensive view of every single device in order to be able to effectively troubleshoot the whole network.
  • Scalability You want a single network diagram tool to be able to not only identify which parts of your network need to be upgraded but also to grow with your company.
  • Live Monitoring You don’t want to see a map of your network from a week ago. Live monitoring lets you stay up to date with your whole network at all times.

The Best Network Diagram Tools

1. SolarWinds Network Topology Mapper – FREE TRIAL

SolarWinds Network Topology Mapper

The SolarWinds Network Topology Mapper is not one of the most popular network diagraming tools out there without a reason. It has everything you would expect from a top-notch network mapping tool while maintaining a cheaper price than most. At just $1,537, the SolarWinds is a lot cheaper than most other premium solutions.

Main Features:

3. ManageEngine OpManager Maps

ManageEngine OpManager Maps

The OpManager network mapping tool will monitor your network by using its SNMP (Simple Network Management Protocol.) The best thing about SNMP is the speed at which it can give you a detailed outlook of all of your network devices.

Whenever the OpManager sends out a status request, every device in the network responds with its full status, including all of its identifying features and settings.

Main Features:

  • Devices respond to status calls with full information.
  • Easily scalable due to its SNMP approach to network mapping, making it ideal for businesses of all sizes.
  • Complies a list of all of your equipment, and instantly generates a topological map from the available list of devices.
  • A variety of available map layouts makes choosing how to view your maps a breeze
  • New devices being added or existing devices being retired from the network will be noticed in a matter of minutes
  • The OpManager doesn’t feature any partial packages, so when you buy the system, you’ll get the tool.
  • Installs on both Windows and Linux
  • A 30-day free trial is available

All in all the ManageEngine OpManager is an excellent complete network monitoring solution. Its scalability, versatility, and flexibility let it earn a spot on this list. With that being said, its UI does leave something to be desired.

4. ConceptDraw Pro

ConceptDraw Pro

ConceptDraw Pro is the ideal network mapping solution for any medium-sized business or any small business with some disposable funds. The UI is quite similar to the Microsoft Visio(another tool that didn’t make the list.) Although the ConceptDraw UI is even easier to use.

Main Features:

  • Easy to use interface
  • MUCH lower price than most other solutions at $199
  • Allows you to make a variety of different visual displays for your network, as well as export into a Visio file.
  • It’s possible to automate the process by using features like Smart Connector and Building Plan Designer in tandem.

The biggest upside of the ConceptDraw tool is its sheer ease of use. If you can make your way around Word, then you can use the ConceptDraw Pro without any issues. Its capability to create extremely complex designs through this simple interface is what helps it stand apart from the rest, and what makes it an excellent starting network mapper.

With that being said, all that simplicity does come at a cost. The more advanced features of its competitors are either difficult or nigh impossible to attain here. Because of this, larger businesses should steer clear of ConceptDraw.

5. Lucidchart

Lucidchart

Lucidchart is not a well-known network diagram tool, however, that does not mean it isn’t a great one.

If you’re a small business looking to get to grips with network mapping right out of the box, and immediately jump into building your own IT environment diagram, then this is the tool for you. It helps you and your business hit the ground running in terms of network mapping.

Main Features:

  • Very cheap, coming in at $4.95 for a single user, or $20 for a whole team of admins
  • You can import existing diagrams into this software through a Visio file, which makes it great to use if you’ve already got hand-inputted network maps.
  • Features an automatic discovery plugin called UVexplorer
  • Simple UI that makes using it a breeze

All in all, Lucidchart is a tool that knows what it is and what it wants to be. It offers you a cheap and easy-to-use entry into network graphing. Its biggest weakness is its lack of additional functionalities, as well as a relatively weak auto-discovery feature. It is also relatively difficult to scale into a larger business.

6. CADE

CADE

The CADE network diagramming solution is the first entry on this list to be completely free of charge. It strips away the fancy UI elements found in more premium solutions and provides a complex 2D vector editor.

Main Features:

  • The tool can be downloaded online, making it an excellent choice in case you’re looking for something more remote.
  • Remote users can provide their contributions at any point
  • It’s entirely free
  • It can export to EMF, XAML, PDF, and JPG
  • You can make unique cables that help you mark differences between similar devices

The main weakness of CADE is its lack of an auto-discovery feature. Although the tool is flexible, that doesn’t mean anything if it isn’t efficient. After all, one of the most flexible tools out there is a piece of paper, and that isn’t very good for network diagraming.

With that being said, if you’re a smaller team dealing with networks that don’t change for half a year or more, then this might just be the tool for you.

7. Network Notepad

Network Notepad

Network Notepad is a free app for Windows made with the idea of network mapping in mind.

Main Features:

  • The Cisco Discovery Protocol Neighbor Tool or CPD is Network Notepad’s alternative to an auto-discovery system. It allows you to look through your devices, and pull info from their elements through CDP information.
  • Easily supports creating multi-page diagrams, as well as vector-based graphics, flow charts, and much more.
  • It’s free, with a professional version available that packs more features

All in all, Network Notepad is a great tool for small teams without much of a budget that still has a need for a robust and complex network diagramming tool.

Choosing the right Network Diagram Tool

Although making your own network map might appear to be a Herculean task when you’re looking at everything that needs to be done, network mapping tools make the whole process far easier. They make sure that you won’t need to spend hours upon hours droning upon a file jotting down device after device just for you to understand your network.

If you’re ready to grasp a bit more complexity and invest a bit more money, then an auto-discovery feature makes this process an absolute breeze.

Keep in mind that today, network diagram mapping tools are quite underused, meaning that taking advantage of a well-made one is an important edge to have on your competitors. This is especially true today, in the age of complex network infrastructures.

Through involving network diagramming tools into your network monitoring process, you make sure that you’ll have the minimum visibility that you’ll need in order to treat yourself to an impeccable view of your whole network. It’s worth keeping in mind that the better look you have at your network, the easier it is to adapt it and kick your performance up a notch.
