This is not about your computer connected to the printer or a few devices connected to your organizational network.
It’s much deeper and bigger.
Although mapping is easier for a network involving a few devices, it’s difficult for an organization with thousands of devices in its network.
It becomes tougher for the IT team to discover every device in the network and monitor it. The process may take significant time, effort, and resources.
Therefore, automatic network discovery tools are a solution to detect all the devices in your network.
With this modern solution, you never lose any path you have created for your growing business network. It will also eliminate manual mapping of all the devices or maintaining data in a spreadsheet.
And if all the devices are mapped perfectly and maintained, you will know what’s connected in your network, monitor everything, and secure the network.
Let’s understand this more and find the best automatic network discovery tools in the market.
What is Network Discovery?
Network discovery is a solution or process that helps you discover devices and systems connected to a given network. It is the initial step a network administrator will take when they need to map and simultaneously monitor their network infrastructure.
Similarly, using network discovery tools, you not only can discover devices connected to your network but also map the combinations of cloud servers, wireless networks, wired networks, and virtual servers.
You can also refer to network discovery as topology discovery.
The first objective for network discovery is to find all the IP addresses on your network, including abandoned, reserved, static, and dynamic IP addresses. The importance of mapping is twofold:
It ensures every IP address is valid and is not being used by a rogue or malicious device.
It ensures the network is set up effectively without leaving any of the abandoned subnets or IP addresses to be used for another purpose.
If a device has some open ports not necessarily used by any device, this could trigger a security vulnerability. To this, network discovery is useful to determine which ports are open and which ports are in use on each device. This way, you can map those open ports and keep them close to prevent intruders’ access and minimize security risks.
How does Network Discovery work?
It is possible to map all the devices manually, but it will take a lot of time and can be risky due to the possibility of mistakes. So, if you want to map every device in the network quickly, it is preferable to use automatic network discovery tools.
The discovery tools scan your whole network address space using network protocols, including SNMP. Once a new device is discovered in the network, the tools automatically update your IT inventory in seconds.
With advanced network discovery software, you will find a visual representation of the network devices connected to your network. These scanners also let you generate custom views and maps of the network devices, keeping you up-to-date with detailed and accurate information.
Why is Network Discovery Essential?
With the growing business, the network will also grow. Thus, your network will add various network devices constantly, such as servers, switches, laptops, printers, routers, and more, to the IT environment.
Managing such a vast network is difficult for network admins while mapping all the devices in your network. To reduce such complexities and security risks, network discovery tools are useful.
Let’s understand its benefits.
Whenever there is a small change to a network system, like adding or removing a new interface, it must be reflected in your dashboard to help you be updated.
Network discovery tools work with network monitoring solutions by discovering every device in your network and updating each data in the network monitoring solution.
Network scales faster, especially if you are a growing business. Hence, if you manually start tracking every device in your vast network, you may lose significant time that you could have invested in innovation. In addition, it could lead to human mistakes, which can transform into a security risk.
But by using network discovery tools, you can automate the whole process of mapping and monitoring every single device to save time and labor.
Continuous Monitoring and Maintenance
A minor issue in the network can cause a big problem that can lead a business to lose millions of dollars. A network discovery tool can help network admins continuously discover and monitor network devices to prevent the issues from the start. These tools can prevent security breaches by ensuring no single network port is open to exploitation.
Let’s now look at the best network discovery tools to simplify the process of detecting all the tools in your network.
