Free networking tool that lets us quickly check for open ports and gather MAC addresses
Pros and Cons
  • "Nmap's performance is great, and I've never noticed any issues in this respect. It really doesn't put a heavy load on the machine when using it."
  • "Since I started using Nmap, it has been completely based on the command prompt and I think it would help other users if they implemented a decent GUI as well."

What is our primary use case?

We are a manufacturing company and there are two main ways in which we use Nmap. The first way is using Nmap as a tool to determine whether certain services are running or whether certain ports are open. If a machine is not available for some reason, then we will first use Nmap to check whether the machine's ports are open or not. This is our most common use case.

The other reason we use Nmap is to gather the MAC addresses of all the machines in the network.

In total, there are about two or three people who use Nmap at my company because we are working in manufacturing and only require a few people to perform this kind of networking troubleshooting. 

What is most valuable?

Nmap's performance is great, and I've never noticed any issues in this respect. It really doesn't put a heavy load on the machine when using it.

Another nice thing about Nmap is that if you know the command prompt, the UI works well and is not too complex.

What needs improvement?

Since I started using Nmap, it has been completely based on the command prompt and I think it would help other users if they implemented a decent GUI as well. In any company you might have multiple experts and a few new people; for the new people the command prompt is usually difficult to grasp at first, but with a GUI they could very easily get started with troubleshooting and playing with different options.

For how long have I used the solution?

I have been using Nmap for about five years.

What do I think about the stability of the solution?

There are no problems with stability that I've observed.

What do I think about the scalability of the solution?

The scalability is okay. It's easy and quick to use, and doesn't put a heavy load on the machine.

How are customer service and support?

I don't have any experience with technical support for Nmap, mainly because I don't use that many features and so I have no need for support. And with the features that I do use, I always get proper results.

It would likely be another story if we were an IT company but since we only work in manufacturing, we don't have a need for anything other than the simplest of support.

Which solution did I use previously and why did I switch?

We are also using Wireshark for troubleshooting, but not in combination with Nmap as it is a different tool for different processes.

How was the initial setup?

The setup process is very simple.

What's my experience with pricing, setup cost, and licensing?

Nmap is open source software, which suits us well because we are a manufacturing company and not an IT company, for example. If we were an IT company, we would probably need to pay for extra support or instead go for another software solution. But as it is, we don't have any need for high-end troubleshooting tools.

What other advice do I have?

I would definitely recommend Nmap to Indian companies and others who are looking into their networking, especially when it comes to troubleshooting server-side resources such as with SaaS, IaaS, or anything which requires checking for open ports. It works very nicely for troubleshooting, because when a service isn't running for any of your users, you can use Nmap to check it directly and easily determine whether the service is actually running or not.

I would rate Nmap a nine out of ten.

Provides network scanning to map the network, identify devices, but lacks support

What is our primary use case?

Nmap is used for network scanning to map the network, identify devices, and assess their status. It helps determine open ports and services running on a particular endpoint or server within an enterprise environment.

What is most valuable?

Nmap is a very useful tool for network discovery and security auditing. To fully utilize its capabilities, you should use features based on your specific requirements. Since it's primarily a scanner, its main function is to perform various types of network scans. The comprehensive scanning capabilities are the core feature of this tool, making it indispensable for network administrators and security professionals.

The scanning process discovers all those assets, identifies their IPs, detects the hosts, and determines the services running on those hosts. This makes Nmap very helpful at an enterprise level.

What needs improvement?

It is an open-source tool, and its scripts are updated by the community. While it might seem that the tool is old, it remains relevant because users can develop and contribute new scripts. The Nmap community may not always appear highly active, but contributions from dedicated users continue to keep it valuable. It is is not actively developed in terms of its GUI. As a result, it looks very outdated and hasn't seen much improvement. Additionally, the built-in scripts provided by the tool are also quite old and are not updated frequently.

For how long have I used the solution?

I have been using Nmap for ten years. 

What do I think about the stability of the solution?

I rate the solution’s stability an eight out of ten.

What do I think about the scalability of the solution?

There is no such automation to do the scalability. 20 users are using this solution.

How are customer service and support?

There is no support. It is only used from by open-source. If somebody else you from the community, then you get the support. Apart from that, there is no sort of active support.

Which solution did I use previously and why did I switch?

I use a lot of scanners, but it's costly, like Qualys and Nutanix. As an independent consultant, I don't have the budget for enterprise-level scanners or procuring licenses. So, I use Nmap, which saves me a lot of money.

One advantage of Nmap is that it's free. Additionally, it can be deployed anywhere since it is available on the cloud. You can download it from GitHub or the Nmap website. Nmap includes various scripts and scan types, and it has extensive support for multiple operating systems, servers, and devices. Its effectiveness largely depends on the user's expertise. A knowledgeable user can leverage its full potential. Nmap can perform well compared to some enterprise tools, though enterprise solutions often offer more sophisticated, interactive reports. Nmap’s reports are typically text-based and may seem outdated

How was the initial setup?

It just takes less than a minute to set up. You can do it on prem, the server, whereever instance you want. It is having both capability.

What was our ROI?

It saves you a lot of money from procuring some sort of enterprise scanners, but, enterprise scanners have their own deduction capabilities. Nmap is always a good start to do the seven figure business months without spending any money.

What other advice do I have?

It is a powerful security detection tool when used effectively. However, its effectiveness can be limited if the target organization has strong security mechanisms and good scanner fingerprinting techniques. In environments with robust security and zero-trust policies, Nmap scanning becomes challenging.

Nmap can be automated using scripts with Ansible, Bash, or PowerShell. It's available on Windows and can be used with PowerShell. While automation with AI is possible, it might be challenging due to the complexity and specifics of Nmap's operations.

it is free to use. You can install and explore the tools. Nothing is gonna harm you. You can just explore it. If it fits your requirement, you can obviously go ahead with it.

Overall, I rate the solution a seven out of ten.

Displays all the services that are exposed within a permission system

What is our primary use case?

We use the solution to add up the router on a network.

What is most valuable?

Nmap can display all the services that are exposed within a permission system. It offers an option to optimize the scanning process, ensuring that our scans remain undetected by other security tools integrated into the automation system. Additionally, Nmap provides features to adjust the nature of the scan, allowing it to bypass security tools such as EDP and base. Furthermore, it includes options to optimize scan response time and duration.

What needs improvement?

Sometimes, the solution doesn't provide the names of services. We find a solution, but we do not entirely know about it. It utilizes a database of services. When the solution scans, it matches the data obtained from the scan with the entries in the database to display the names of services at the target site. For example, we might have an exposed port but remain uncertain about the associated service. Nmap can identify what services are running and their associated products. It doesn't allow exploiting vulnerabilities automatically. However, having such capabilities could greatly enhance security, particularly for servers exposed to the internet. 

For how long have I used the solution?

I have been using Nmap for one and a half years.

What do I think about the stability of the solution?

The product is stable.

How was the initial setup?

The initial setup is simple.

What other advice do I have?

Overall, I rate the solution an eight out of ten.
