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.

CEO at IOPoint.com

Offers perfect real-time bandwidth monitoring and SNMP functionality

The licensing policy needs to change. The current model requires customers to purchase a minimum of two thousand licenses, which is not flexible for all customers. They should consider a more flexible licensing approach. Furthermore, alignment with customer expectations rather than offering numerous features that are not requested would be beneficial.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Nmap is easy to use. It's a command-line interface, and the output is quite good."

"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."

"It is a very user-friendly product."

"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 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 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 is mostly helpful during compliance checks. We run the scanner to see how many devices are on our network and find vulnerabilities in those that aren't compliant. We also use it monthly to scan our network and identify devices that aren't connected properly. This helps us detect any issues related to the operating systems of these devices."

"It enables us to delve deeper and identify the services and open ports on the system and visualize this information on a dashboard automatically."

More Nmap pros

"What I really appreciate about PRTG Enterprise Monitor is that it is very easy to set up, especially the configuration, which is not complicated, and it is very straightforward to go in and change things."

"From a technical perspective, the product's most valuable feature is SNMP, an open standard monitoring protocol that works across various network devices and operating systems, including UNIX and Windows."

"The solution offers perfect real-time bandwidth monitoring and SNMP functionality."

"The product's most valuable feature is network analysis."

"It provides a vast array of options for dashboard creation and monitoring of the activities within the environment."

"It can identify downtimes and disruptions."

"The product is easy to use and you don't need to have any training. You can use it even if you don't have an IT background."

"PRTG is good and very easy to use."

More PRTG Enterprise Monitor pros

Cons

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

"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."

"They should deliver Playtech's username and password."

"The solution's initial setup could be better."

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

"The price is high and could be cheaper."

"Customization is not very user-friendly in Nmap."

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

More Nmap cons

"The licensing policy needs to change."

"There is no unified monitoring in PRTG. It needs a lot of improvement in terms of integration."

"The solution could be improved by introducing security features similar to those available in Teams, as the current version only monitors devices and does not integrate IoT or OT devices."

"They should work on minimizing false positives by sending alerts promptly and confirming errors with minimal troubleshooting requirements."

"The solution could be improved by introducing security features similar to those available in Teams, as the current version only monitors devices and does not integrate IoT or OT devices."

"The solution could be improved by including a processing monitor, possibly with a language interface like Lua, allowing for writing custom sensors and processing outcomes of inputs."

"There could be more security features included in PRTG Enterprise Monitor."

"In my opinion, one area that could be improved in PRTG Enterprise Monitor is the capability to send SMS notifications. Notifications are crucial for alerting us to areas that require attention."

More PRTG Enterprise Monitor cons

Pricing and Cost Advice

"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 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."

"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."

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

"Nmap is an open-source product. You don't need a license to install it."

More Nmap pricing and cost advice

"The pricing is $2,149 for software without maintenance, and licenses are sold in the minimum bundle of 500 interfaces."

"PRTG Enterprise Monitor is an expensive product."

"I rate the product's pricing an eight to seven out of ten."

"PRTG Enterprise Monitor's pricing is reasonable."

"The solution is affordable."

Overview

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).
