Easy to set up with good documentation and helpful support
I'm using it for a customer The packet flow switch is the most valuable aspect of the solution.  It's an easy product to set up. We can scale the solution if we need to. It's stable.  The documentation is well-written and quite useful. It's compatible with other products.  Under the pocket flow…

Penetration testing has become efficient as I identify open ports and security risks with confidence
Nmap could potentially become a GUI and provide automatic reports with one-click downloads. For example, the report could show all the open ports for an IP address with a professionally formatted report. This is a far-fetched suggestion and not really required, but it could make the work a little better. On a scale of one to ten, I give Nmap a solid nine. I mean, how can you fix something that is not broken? Nmap is already the best, and I do not think there are any other features that can be added. Its job is reconnaissance, so I do not think there is more to add to it. However, if I get any ideas, I will let them know about this.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Go with NETSCOUT."
"We use it for monitoring whenever we update a new circuit or site."
"We are attracting customers in good sized numbers as we advertise and market this solution."
"The solution has helped to increase application and network uptime, reduced our mean time to repair significantly for application and network issues, and cut our overall troubleshooting time from an hour down to five minutes."
"The real-time troubleshooting and application segregation that you can do within it."
"It has cut our group's troubleshooting time down significantly, e.g., depending on the issue, what would normally take maybe a couple of hours will now take minutes."
"It helps us get to root cause quickly. With utilization and consumption of bandwidth, we can usually see what application is taking as much as they should (or shouldn't), then account for it accordingly."
"It allows us to get quicker resolutions. We can see exactly what is using up the bandwidth, so we can assist end users."
"The solution detects the operating systems, which makes testing the software much easier before making the payload."
"The initial setup was simple."
"It is most efficient network scanner right now."
"It enables us to delve deeper and identify the services and open ports on the system and visualize this information on a dashboard automatically."
"The solution really is not comparable to other products because of its many features."
"The most valuable feature of the solution for security audits stems from the fact that it serves as a powerful tool with the ability to scan a large number of ports."
"This was my first project, and Nmap was the best tool that I have used to date, and I recommend it to everyone."
"The best feature of Nmap is that it lets me see useful information about each endpoint in my entire network environment. For example, I can see every single connection of the network as well as each and every port."
 

Cons

"The single pane of glass feed still needs work."
"We don't use the single pane of glass view, even though we own it."
"The monitoring and reporting tool needs improvement. Users want more information, such as the level of detail when doing a packet analysis. They want more detail to be able to isolate down to a specific point."
"The monitoring and reporting tool needs improvement."
"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."
"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"The NetFlow Collectors could handle more flows per minute."
"There is no support."
"The solution should increase the number of features under a free license."
"I would like something more user-friendly to use and export data to various software."
"Nmap needs to improve its scanning speed."
"It takes a bit of time to get familiar with the solution and its options."
"The solution is not that easy for a beginner to learn."
"Nmap will be a little difficult for beginners because of the learning curve and the CLI-based system, but once you get the hang of it, it becomes very powerful."
"One of the drawbacks of the standard Nmap utility is that it does not come with a graphical user interface, unlike a number of other open-source alternatives such as Zenmap."
 

Pricing and Cost Advice

"The scalability is good, but it comes at a cost. E.g., if you need 100 InfiniStream because you are sending gigs or terabytes of data to one InfiniStream, then you will have to purchase another InfiniStream, which are not cheap."
"This product could be cheaper."
"The price is a little high."
"It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site."
"I would like it to be more scalable with less spend."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"Nmap is an open-source and free product."
"I am using the standard free version of Nmap."
"The product's pricing is fine. The licensing options for Nmap include perpetual licenses and volume-based licenses. For perpetual licenses, once you purchase it, there's no need to invest in renewals. And for volume-based licenses, enterprise companies can use it multiple times based on the number of users or devices they need to scan. It's a pay-as-you-go model, similar to how you pay for what you use."
"It's an open-source solution. Commerically, only the support service is available."
"The solution is free of cost, but there are specific services that we have to buy."
"The solution is open source so it is free."
"Nmap is an open-source product. You don't need a license to install it."
"I am using the free version of Nmap."
