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

"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."
"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."
"It helps us secure the network infrastructure."
"Nmap has a powerful command line tool and a set of diagnostic features."
"The initial setup was simple."
"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 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 easy to use. It's a command-line interface, and the output is quite good."
"PRTG Network Monitor is user-friendly and offers flexible alerting systems."
"Accessibility, ease of use (Web GUI, MobileApps). In general, compared with other software"
"The most valuable feature is the ability to span multiple technologies and multiple vendors."
"The email notifications are helpful, and the dashboards are user-friendly for people with little network monitoring knowledge."
"PRTG is relatively intuitive and fairly straightforward. It has net flow monitoring and that works all right. I would describe it as a decent middle-of-the-road solution."
"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."
"The most valuable features of PRTG Network Monitor are bandwidth utilization, user-friendliness, all past report simple retrievals, and timeout features. Additionally, if the solution does go down it is simple to bring it back."
"One of its valuable features is the fact that it handles multiple operating systems... And I like the fact that it tells me when things are about to fall over, which means I can preempt it and not have to wake up at three in the morning to fix it."
 

Cons

"The solution is not that easy for a beginner to learn."
"Nmap major operates through the CLI; there's no GUI component, and that's where the challenge is."
"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 solution's initial setup could be better."
"The solution should increase the number of features under a free license."
"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 price is high and could be cheaper."
"There are concerns with the stability of the product, making it an area where improvements are required."
"PRTG Network Monitor could improve by having a feature to allow uploading of preset standard network switch configurations and the ability to monitor the SLA configuration, such as uptime for the switches or internet connectivity. This would be very useful."
"More training videos for installing and configuring this software would have been nice, especially when working with a lot of devices."
"When using PRTG Network Monitor it is beneficial if you have prior experience with it, the user interface could improve."
"The automation should be improved."
"I have an issue with DFS, distributed file services... there isn't one by default. Taking into account the difference between DFS and DFSR as well would be great."
"PRTG Network Monitor is okay to use, but you'll need some time to analyze the data. If it can automatically locate or identify the problem area, it would be more helpful to users."
"PRTG Network Monitor can improve the reports. In the reports, you have to give an alert for that SMS and email, the emergency calls and downtimes have to be reported accordingly. You have to enable email services or an SMS gateway service to receive more alerts at the proper time."
"We would like to monitor certain aspects of the user experience. We should be able to analyze the cause of end user experience, bad or good, so we can do some research and development on our own."
 

Pricing and Cost Advice

"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 am using the standard free version of Nmap."
"Nmap is an open-source and free product."
"The solution is free of cost, but there are specific services that we have to buy."
"It's an open-source solution. Commerically, only the support service is available."
"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."
"I would like better pricing models for smaller businesses. The free version is fantastic, but it's too restrictive. If they could just get up to 200 sensors for a reasonable fee for on-premise, I would give PRTG my credit card right now."
"The scalability is there, but smaller companies might need CAM software to be able afford the product."
"We have unlimited devices and sensors, and it is a bit pricey, but we do have unlimited sensors. With all things considered the price is fine, related to the solution itself. PRTG Network Monitor is good value for money."
"Pricing for PRTG Network Monitor is a nine out of ten. It meets my company's budget and monitoring requirements. My company is on a perpetual license."
"The pricing for PRTG in our case is reasonable because we have a lot of applications to monitor within PRTG. It is not that expensive."
"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."
"Licenses are very expensive, so I would like to see cheaper licensing."
"The price is pretty comparable."
