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

"The real-time troubleshooting and application segregation that you can do within it."
"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."
"Because we are doing proactive monitoring instead of reactive, the end users don't even see that there is something wrong."
"We use it for monitoring whenever we update a new circuit or site."
"The technical support is really good. They will go above and beyond, if you are running into a problem. You can go to a sales engineer, who will engage technical support to help you out."
"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."
"This solution has cut our overall troubleshooting time, sometimes going down to a few hours over what might have taken one to two days to fully troubleshoot an issue, and it has helped to increase our application uptime as we try to keep the five nines."
"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’s an excellent tool and allows its users a multitude of solutions to scan a network."
"From a functionality standpoint, it's robust and straightforward to comprehend."
"It helps us secure the network infrastructure."
"It enables us to delve deeper and identify the services and open ports on the system and visualize this information on a dashboard automatically."
"We chose this solution because it supports several frameworks, including coding frameworks."
"The most important function, according to me, is the capability to use some arguments in the scanning. The solution's capability to go figure and do a deep dive, discovering information on specific aspects."
"Nmap has a powerful command line tool and a set of diagnostic features."
"The scanning procedure includes UDP ports which sets it apart from competitors."
 

Cons

"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM. I don't like when devices go end-of-life on us so quickly. If we can get more of an advanced notice of when an end-of-life is brought up, because our certification process within the organization takes a while."
"Sometimes, we can't access 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."
"I'd like them to make the product more user-friendly."
"It's not able to communicate with our probes."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."
"The stability depends on who is using the tool, because you only can get as much out of the tool as you put into it. There are a lot of patches for this particular environment, so you have to keep on them. If you lose track of them, then the product is not useful anymore."
"There could be a specific option to check non-pingable endpoints for the product."
"There is no support."
"Nmap needs to improve its scanning speed."
"The challenge often lies in finding suitable courses and professional resources."
"The tool's license limits the number of scans it can perform. Improving the license model could benefit customers by allowing more scans for compliance and other purposes."
"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."
"I would like something more user-friendly to use and export data to various software."
"The solution's initial setup could be better."
 

Pricing and Cost Advice

"This product could be cheaper."
"The price is a little high."
"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."
"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."
"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."
"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."
"The solution is free of cost."
"I am using the free version of Nmap."
"It's an open-source solution. Commerically, only the support service is available."
"Nmap is an open-source and free product."
"It's an open-source product, and I haven't seen any premiums. Options are available for those who purchase, but for my use case, everything I need is available in the community and forums."
"The solution is free of cost, but there are specific services that we have to buy."
"I am using the standard free version of Nmap."
