Scans the network and identifies vulnerabilities on each machine
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. The tool's most valuable feature is its vulnerability scanning. It allows us to scan a specific range of IP addresses and discover devices within that range. This makes it easy to identify devices and view their details. Port scanning is crucial for network management tasks. It helps us identify vulnerabilities by finding open ports that may be unused or misconfigured. This tool makes it easy to detect such issues. The OS detection feature is great. Unlike other tools, Nmap provides accurate information about asset vulnerabilities, helping us easily detect and address them. Using Nmap provides value to the company, especially during compliance audits. It helps generate reports on assets, updates on workstations, and insights into network activities and potential attacks. Additionally, Nmap detects vulnerabilities and provides port details, allowing us to close unused ports on the client machines.

Efficiently monitor networks across regions with seamless setup and robust feature set
PRTG Network Monitor is easy to set up. Within a few minutes, it is operational. It is an all-in-one monitoring solution without extra costs. For example, we set it up for an insurance company with branches across Africa. We are able to monitor from Lagos without installing anything in the branches, using the agentless feature. We just put in the IP address and the parameter, and we monitor from those ends. Additionally, all the sensors are very useful. Most people are interested in the bandwidth monitoring sensor to see what bandwidth the users are consuming. The pricing is affordable compared to SolarWinds.

Quotes from Members

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

Pros

"It enables us to delve deeper and identify the services and open ports on the system and visualize this information on a dashboard automatically."
"It is a very user-friendly product."
"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."
"Nmap is easy to use. It's a command-line interface, and the output is quite good."
"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 has a powerful command line tool and a set of diagnostic features."
"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."
"The scanning procedure includes UDP ports which sets it apart from competitors."
"Its initial setup process is fast and easy."
"It is very flexible, and we can monitor many aspects of IT as well as ERP and CRM services. It has a very powerful interface and APIs for customization."
"It improves the status of my infrastructure, from networking devices to real-time machines."
"The most valuable feature of PRTG Network Monitor is the different monitoring probes available."
"My opinion is that this solution is not very expensive."
"The alerting is the most valuable feature. I also like the iPhone app. I get alerts in an email on the iPhone app."
"PRTG Network Monitor is easy to set up. Within a few minutes, it is operational."
"Its proactiveness is its most valuable feature. We already know when we come in, in the morning, if a server or site is down, as opposed to someone telling us."
 

Cons

"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."
"Nmap needs to improve its scanning speed."
"Nmap major operates through the CLI; there's no GUI component, and that's where the challenge is."
"There could be a specific option to check non-pingable endpoints for the product."
"The price is high and could be cheaper."
"The challenge often lies in finding suitable courses and professional resources."
"The tool's license limits the number of scans it can perform. Improving the license model could benefit customers by allowing more scans for compliance and other purposes."
"The solution is not that easy for a beginner to learn."
"I would like to see more updates available in this solution."
"There is room for improvement in this solution for the performance and third-party monitoring protocols. They need to be updated to the latest ones."
"The product could be improved by being cross-platform friendly."
"In the next release, PRTG Network Monitor should add a backup solution."
"The scalability of this solution could improve as well as the automated provisioning of the infrastructure."
"I wouldn't mind better categories for the sensors. When I go to add a new sensor for a new device, there are some categories in there already, and they can be filtered out, but there's quite a large pool of sensors... When I want to go in and find something quite specific, I have got to scroll down and scroll down to find what I'm actually looking for,"
"The free version only gives us 100 free sensors to use. It would be nice if there was double that."
"PRTG Network Monitor could improve the price."
 

Pricing and Cost Advice

"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."
"I am using the free version of Nmap."
"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."
"Nmap is an open-source product. You don't need a license to install it."
"I am using the standard free version of Nmap."
"The solution is open source so it is free."
"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 rate the licensing for PRTG Network Monitor an eight out of ten."
"The licensing fees are billed annually and there are no costs in addition to this."
"Because we are only on the free version, we have a limited number of sensors. Therefore, we are not monitoring as much as we want to be to obtain historical information."
"Our licensing costs are 10,000 euros over three years."
"We are using the premium version of PRTG Network Monitor. The price of the solution is a bit higher than competitors but it is worth the extra money. However, it would be helpful if the price was lower."
"The pricing is okay and it is cheaper than some competing products."
"PRTG Network Monitor's price is a little high."
"Licenses are very expensive, so I would like to see cheaper licensing."
