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.

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

"It's all today portal-based which is a good feature for us."

"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 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."

"It is a very user-friendly product."

"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'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."

"It helps us secure the network infrastructure."

"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."

"Nmap has a powerful command line tool and a set of diagnostic features."

"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."

"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

"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.

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. 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."

"There is room for improvement in the design, the GUI. It looks a bit odd. Maybe Nmap should improve it or add more widgets to make it more attractive, but the basic functionality is good and provides what we need."

"There could be a specific option to check non-pingable endpoints for the product."

"There are concerns with the stability of the product, making it an area where improvements are required."

"Nmap major operates through the CLI; there's no GUI component, and that's where the challenge is."

"The solution should increase the number of features under a free license."

"The price is high and could be cheaper."

"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."

"The challenge often lies in finding suitable courses and professional resources."

Pricing and Cost Advice

Information not available

"The solution is free of cost, but there are specific services that we have to buy."

"Nmap is an open-source and free product."

"The solution is open source so it is free."

"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 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."

"I am using the standard free version of Nmap."

Fortra

Nmap ("Network Mapper") is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping).
