Nmap Reviews

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. 

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.

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.

I have been using Nmap for about five years.

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

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

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.

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

The setup process is very simple.

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.

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.

I use the solution for scripting and scanning ports before purchasing them. It makes it much easier because when you know a port is open, you can directly focus on it as vulnerable. The solution detects the operating systems, which makes testing the software much easier before making the payload.

When you know a port is open, you know what to do next. The solution helps us know the ports, detect the operating systems, and collect information about the machine.

The solution is not that easy for a beginner to learn.

I have been using Nmap for two years.

Nmap is a pretty stable solution.

The solution's initial setup is easy. It comes pre-installed on Linux, but I have seen people using it on Ubuntu.

I am using the free version of Nmap.

Since the solution is not easy for beginners, I recommend it to someone experienced. Utilizing the solution's operating system detection capabilities to know the OS is crucial while performing penetration testing. Attacking Windows is much easier than attacking a MacBook.

Overall, I rate the solution ten out of ten.

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

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.

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. 

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

The product is stable.

The initial setup is simple.

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

The tool helps with tasks such as network integration and mapping. Nmap comes equipped with numerous scripts that aid in identifying the operating system and  available ports. 

My web team uses the product during routine penetration testing. 

The tool's most valuable feature is its scripts. These scripts prove beneficial when security features may obscure or block connections. Nmap helps identify vulnerabilities across different systems, including web servers and various server types.

Nmap needs to improve its scanning speed. 

The solution's stability is pretty good. 

The tool is not deployed on a shared environment. It is deployed as an individual setup. 

Since it's an open-source tool, I haven't specifically sought support assistance. However, the community is very active. There are active forums where people communicate, and it's an open environment where anyone can ask questions. 

Nmap's deployment is straightforward. 

Nmap is a free tool, so it helps save a lot of time when identifying vulnerabilities on the network.

Nmap is an open-source and free product. 

You can install the product on any endpoint. Analysts should have it, especially those in red teams or penetration testing. Anyone interested in cybersecurity or any related field should know how to use Nmap. I rate it a ten out of ten. 

We use the solution to scan and monitor ports. We can get insights into operating systems, status, protocols, and services.

The solution's most valuable feature is scanning.

The solution's initial setup could be better. Also, they should provide more insights into the network infrastructure.

I have been using the solution for two years.

The solution's initial setup process is complicated. It requires specific skills to execute the implementation.

It is a free source application.

It is a beneficial tool for scanning. I rate it as an eight.

The price is high and could be cheaper. The third-party library vulnerability assessment could be included in the next release.

We have been using the solution for seven months.

The solution is stable. I rate the stability an eight out of ten.

The solution is scalable. Approximately 100 people in our organization utilize it.

We have not had experience with customer service and support.

The initial setup was simple and took us approximately five days.

We chose this solution because it supports several frameworks, including coding frameworks.

I rate the solution a nine out of ten.

Three technicians in our company use the solution extensively to scan our environment and find security holes. 

The solution is powerful for troubleshooting and finding security holes in services. 

The scanning procedure includes UDP ports which sets it apart from competitors. 

It takes a bit of time to get familiar with the solution and its options.

A scan to determine whether a service or application is lost would be a useful addition. For example, a scan that checks whether a service in layer seven is blocked by a server or host. 

A graphic interface for Windows would be helpful. 

I have been using the solution for one year. 

The solution is really stable. 

The solution is scalable. 

I have not needed technical support. 

The setup is quite simple. 

The solution is open source so it is free. 

The solution really is not comparable to other products because of its many features. We looked at Wireshark but there's really no comparison. 

I rate the solution a nine out of ten. 

Nmap is a tool for analyzing perimeter security and application output.

Nmap is easy to use. It's a command-line interface, and the output is quite good. 

Were a mid-sized company with about 50-plus employees, and we've been using Nmap for more than five years

Nmap is stable. 

Nmap is easy to scale anytime.

We've never had to contact support. The community on the forums answers our questions.

Port scanning.

I have been able to check open ports on a server to ensure that they meet security requirements.

• I would like something more user-friendly to use and export data to various software.
• Also, I would like to be able to use it as a monitoring tool to check changes on open port.

For five years.

No issues.

I have never tried to scale.

I have never contacted technical support.

Wireshark and a desktop-oriented solution. It is better to work with Nmap on servers.

The initial setup is straightforward. It is installed from repositories.

Nmap is free and should stay this way.

Not really.

Spend time reading the documentation as it is the swiss-knife of port scanning.

These features are very useful:

• Script scanning
• OS detection
• Service detection
• Port scanning.

Script scanning is useful for identifying and confirming the most common vulnerabilities as it has advanced detection capabilities. The Nmap result provides detailed information about each host as an “interesting ports table”. It lists port number, protocol, service name, version and state of the port.

It is designed to scan large networks. It enhances the scanning phase of vulnerability assessment and penetration testing (VAPT). Since it is open source technology, it cuts down on the operating costs.

Script scanning has been updated regularly, expecting it to support more of an application security audit and IoT.

For the past five years, I have been using this tool. I have used this tool for internal/external network vulnerability assessment, web application security audit, etc.

No issues so far. It is a stable version and keeps on improving due to the continuous support from developers and users.

No issues so far. It is capable of scanning huge networks of literally 100,000s of machines.

Nmap comes with no warranty. It is well-supported by a vibrant community of developers and users.

Previously, we were using an advanced IP scanner, SoftPerfect Network Scanner. These scanners made me want to switch between tools for:

• Identifying live hosts
• Port scanning
• OS detection
• Service discovery
• Version identification, etc.

Nmap offers all scanning solutions in one place.

In this economy, employees who can save their employers money are highly regarded and will potentially be in line for advancement. Using open source technology is one great way to help your company cut down on costs across the board.

Yes, we were using tools such as Advanced IP Scanner, hping2, and online port scanner.

It is most efficient network scanner right now. It is fulfilling all our security needs, such as finding the live hosts, operating systems detection, service – version detection, port scanning, and script scanning. Apart from this, 50% of network vulnerabilities can be confirmed using this scanner.

It is one of the best network framework available as an open source technology. Go for this tool if you are planning for network penetration testing, network discovery and troubleshooting, etc.
