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…

Improves network monitoring and offers insights into traffic, including VPNs
The real-time reporting feature of Nmap is particularly valuable. It generates detailed reports on the source and destination IP addresses, the protocols used, and the types of traffic. This feature is crucial for law enforcement agencies to monitor and analyze network connectivity effectively. It also has traffic analysis. For example, assessing bandwidth usage and configuring the tool to track specific types of traffic is crucial. Unlike SolarWinds, which requires configuration for this, Nmap has built-in functionality that allows it to check all 4,000 computer ports. It identifies the type of traffic each port is using and can easily generate reports on network communications between computers, whether there are 100 or 1000 in the network.

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 tool has the ability to look back within a month's data. It is very easy to navigate within the tool and troubleshoot the problem, compared to other solutions that we've used in the past."
"The most valuable feature is utilization."
"We use it for monitoring whenever we update a new circuit or site."
"It's an easy product to set up."
"It has cut our troubleshooting down by days. Once we have a product in place, we show people examples of how it can streamline their troubleshooting process."
"The ability to troubleshoot customers' connectivity has been very beneficial."
"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."
"Nmap is easy to use. It's a command-line interface, and the output is quite good."
"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."
"It helps us secure the network infrastructure."
"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."
"The real-time reporting feature of Nmap is particularly valuable. It generates detailed reports on the source and destination IP addresses, the protocols used, and the types of traffic."
"The solution detects the operating systems, which makes testing the software much easier before making the payload."
"From a functionality standpoint, it's robust and straightforward to comprehend."
"The initial setup was simple."
 

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."
"The NetFlow Collectors could handle more flows per minute."
"The scalability has some limitations and quirks to it. I would like to be able to upgrade rather than replace the whole thing."
"It's not able to communicate with our probes."
"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."
"The single pane of glass feed still needs work."
"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."
"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 price is high and could be cheaper."
"It takes a bit of time to get familiar with the solution and its options."
"Customization is not very user-friendly in Nmap."
"There could be a specific option to check non-pingable endpoints for the product."
"The challenge often lies in finding suitable courses and professional resources."
"They should deliver Playtech's username and password."
"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."
"The solution's initial setup could be better."
 

Pricing and Cost Advice

"The price is a little high."
"This product could be cheaper."
"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 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."
"Nmap is an open-source product. You don't need a license to install it."
"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."
"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."
"I am using the free version of Nmap."
"The solution is free of cost."
"Nmap is an open-source and free product."
"The solution is open source so it is free."
