Cost effective but when we originally purchased LANGuardian, some features needed further development.

Penetration testing has become efficient as I identify open ports and security risks with confidence
Nmap could potentially become a GUI and provide automatic reports with one-click downloads. For example, the report could show all the open ports for an IP address with a professionally formatted report. This is a far-fetched suggestion and not really required, but it could make the work a little better. On a scale of one to ten, I give Nmap a solid nine. I mean, how can you fix something that is not broken? Nmap is already the best, and I do not think there are any other features that can be added. Its job is reconnaissance, so I do not think there is more to add to it. However, if I get any ideas, I will let them know about this.

Pros

"If you are looking for a solid solution that can be easily deployed then I'd recommend considering Netfort solutions."
"Our CIO asked us to track down the source of undesired uploads, which trigger e-mails received by outside bodies regarding what they refer to as "copyright violations", and Languardian was the most efficient and effective tool for the job."
"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."
"The scanning procedure includes UDP ports which sets it apart from competitors."
"The solution really is not comparable to other products because of its many 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."
"Nmap is free and should stay this way."
"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 solution detects the operating systems, which makes testing the software much easier before making the payload."
"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."
 

Cons

"Sure, at the time we bought the product, the GUI and graphs/reports/pie charts etc ... were not fully developed."
"It takes a long time to load results. I think it would be great if they fix the slowness issue in the next release."
"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 price is high and could be cheaper."
"There is no support."
"Customization is not very user-friendly in Nmap."
"It takes a bit of time to get familiar with the solution and its options."
"There are concerns with the stability of the product, making it an area where improvements are required."
"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."
 

Pricing and Cost Advice

Information not available
"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."
"I am using the standard free version of Nmap."
"Nmap is an open-source product. You don't need a license to install it."
"I am using the free version of Nmap."
"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."
"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."
