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 solution detects the operating systems, which makes testing the software much easier before making the payload."
"The scanning procedure includes UDP ports which sets it apart from competitors."
"The initial setup was simple."
"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 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."
"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 has a powerful command line tool and a set of diagnostic features."
"Nmap is easy to use. It's a command-line interface, and the output is quite good."
"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."
"PRTG Network Monitor's best features are its flexibility, ease of implementation, user-friendliness, and intuitive interfaces."
"Stable solution for monitoring networks and bandwidth, with multiple functions and features such as NetFlow Collector, graphical monitoring, etc."
"The solution is easy to manage and the reports are very accurate."
"The email notifications are helpful, and the dashboards are user-friendly for people with little network monitoring knowledge."
"There was only one feature I liked about PRTG Network Monitor a lot, and that was bandwidth monitoring, though, in the newer versions of the tool, that feature is now a bit lacking. Pricing for PRTG Network Monitor is also not as expensive. It's a good tool, even for beginners."
"It is a very stable solution. There are no bugs, glitches and we have not experienced any crashing."
"The solution has excellent redundant features."
 

Cons

"The solution should increase the number of features under a free license."
"Nmap major operates through the CLI; there's no GUI component, and that's where the challenge is."
"The price is high and could be cheaper."
"The solution is not that easy for a beginner to learn."
"The solution's initial setup could be better."
"Nmap needs to improve its scanning speed."
"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."
"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."
"I've encountered a challenge in my functions, particularly in adding and printing."
"The technical support from PRTG needs significant improvement."
"I know we're going to move to Docker applications and I understand that PRTG does some monitoring regarding this. I do not know if it is complete. If it's not yet complete, it's something they should consider improving."
"In our organization, we encounter performance issues with our PRTG probe service. I saw documentation from the vendor or Paessler mentioning that there are limitations for WMI sensors. Other than that, we are okay with PRTG."
"They could improve the process of updating the license."
"It would be nice if it gave us alerts via Gmail or SMS message."
"They just released a newer version of the desktop app, a beta version, that I have been trialing out. I prefer the older version, only because of how the layout is designed"
"In the next release, PRTG Network Monitor should add a backup solution."
 

Pricing and Cost Advice

"Nmap is an open-source product. You don't need a license to install it."
"The solution is free of cost, but there are specific services that we have to buy."
"The solution is open source so it is free."
"Nmap is an open-source and free product."
"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."
"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 solution. Commerically, only the support service is available."
"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."
"The pricing is very low compared to other solutions."
"The pricing is reasonable for the features provided."
"PRTG is now available as PRTG Enterprise Monitor, and the price varies depending on the total number of sensors the customer buys"
"It is expensive."
"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."
"I rate the licensing for PRTG Network Monitor an eight out of ten."
"The price is pretty comparable."
