It tremendously cuts down our troubleshooting timeframe, but needs advanced SLA monitoring and reporting
They can do a better job with SLA reporting. It does some basic reporting, but it really doesn't offer the ability to monitor devices by groups, customers, or carrier to give an overall health performance of specifically-defined environments. That's where HelpSystems Intermapper could have done a better job. I would love to see advanced SLA monitoring and reporting in this solution. They already have a lot of ingredients. They already have SNMP polling. It is really about what people are looking for from SLA monitoring, especially someone who looks at the network topology. You want to see your endpoints. You want to see half of your endpoints by simply analyzing ICMP or SNMP-based availability of your endpoints. Having an ability to define your group and how you bring devices into your group would be a huge benefit.

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 solution has a couple of features which are really interesting; it's not a fancy or expensive solution but we wanted to have a cost effective one and it's doing its job pretty well."
"Right now, it is really a combination of network topology, network monitoring, and network analyzing, so, in my opinion, it is awesome."
"It's a nice graphical interface, a nice map, that relates Layer 1 to Layer 3, virtually instantly, to the Helpdesk support staff. It provides a default place to get critical information so we can deploy our staff."
"The graphical alerting with the ability to obtain a quick overview of a monitored device is my favorite feature."
"Put Intermapper in as your base to start from, hands-down."
"What is really cool about HelpSystems InterMapper is that because of its SNMP base, you can integrate all different makes and models on the same map. You, of course, can have more than one map, but you have an option to have visibility into the entire network from one centralized system. You can monitor IPs, routers, radios, DC power plants, and UPS. You can do it all from one network management and monitoring solution. That's what really makes HelpSystems Intermapper great. Another great thing about HelpSystems InterMapper is that you can really bundle different probes under one device. You can have a bundled device. You can monitor the physical status of a host based on the IP availability. You can also monitor services and actually see if anything happens. You can quickly determine whether it is the application layer, host layer, or network layer. HelpSystems Intermapper gives such a unique representation of a network. Ever since we started using HelpSystems InterMapper, we don't have to document everything in a detailed format and store it somewhere. Right now, it is really a combination of network topology, network monitoring, and network analyzing. So, in my opinion, it is awesome. When you have your SNMP topology defined, you don't require a dedicated NMS engineer to manage your system, which is another great thing about HelpSystems InterMapper. I see how our operators get so excited by having the ability to map a device or interface and connect interfaces together. HelpSystems InterMapper is also very operator friendly; not just user friendly, but also operator friendly. This is a unique feature, and it works really great."
"The most valuable features are its: log history, real-time monitoring capabilities, accuracy - the number of false positives is very low, and the mapping features."
"It's all today portal-based which is a good feature for us."
"Nmap has a powerful command line tool and a set of diagnostic features."
"It’s an excellent tool and allows its users a multitude of solutions to scan a network."
"It is most efficient network scanner right now."
"The solution really is not comparable to other products because of its many features."
"The solution detects the operating systems, which makes testing the software much easier before making the payload."
"The scanning procedure includes UDP ports which sets it apart from competitors."
"It enables us to delve deeper and identify the services and open ports on the system and visualize this information on a dashboard automatically."
"Nmap is easy to use. It's a command-line interface, and the output is quite good."
 

Cons

"I'd love to see more of the network management side of it coming back into it. If we were able to run scripts to bounce ports on switches, that would be great. It's asking a lot, but it's actually very doable because I do it through scripting into other products. If we could incorporate that directly into Intermapper, that would be fantastic."
"I have seen instances where Intermapper does not seem to recover from network changes."
"It's a smaller solution so tools are not as advanced as you would find in a larger solution"
"I'd love to see more of the network management side of it coming back into it."
"They can do a better job with SLA reporting.

"Customization is not very user-friendly in Nmap."
"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."
"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."
"There are concerns with the stability of the product, making it an area where improvements are required."
"It takes a bit of time to get familiar with the solution and its options."
"There could be a specific option to check non-pingable endpoints for the product."
 

Pricing and Cost Advice

Information not available
"I am using the standard free version of Nmap."
"I am using the free version of Nmap."
"The solution is free of cost."
"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 open source so it is free."
"Nmap is an open-source product. You don't need a license to install it."
"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, but there are specific services that we have to buy."
