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 most valuable features are its: log history, real-time monitoring capabilities, accuracy - the number of false positives is very low, and the mapping features."
"Put Intermapper in as your base to start from, hands-down."
"The graphical alerting with the ability to obtain a quick overview of a monitored device is my favorite feature."
"It's all today portal-based which is a good feature for us."
"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."
"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."
"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."
"Right now, it is really a combination of network topology, network monitoring, and network analyzing, so, in my opinion, it is awesome."
"It helps us secure the network infrastructure."
"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 is easy to use. It's a command-line interface, and the output is quite good."
"Nmap has a powerful command line tool and a set of diagnostic features."
"Nmap is free and should stay this way."
"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."
"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."
"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."
 

Cons

"I have seen instances where Intermapper does not seem to recover from network changes."
"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."
"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."
"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."
"The solution should increase the number of features under a free license."
"The price is high and could be cheaper."
"There could be a specific option to check non-pingable endpoints for the product."
"It takes a bit of time to get familiar with the solution and its options."
"Nmap major operates through the CLI; there's no GUI component, and that's where the challenge is."
"The solution is not that easy for a beginner to learn."
"Customization is not very user-friendly in Nmap."
"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."
 

Pricing and Cost Advice

Information not available
"The solution is open source so it is free."
"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."
"Nmap is an open-source and free product."
"I am using the standard free version of Nmap."
"Nmap is an open-source product. You don't need a license to install it."
"The solution is free of cost."
"It's an open-source solution. Commerically, only the support service is available."
"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."
