Sometimes I use it for BlackBox as well in stealth mode and modified commands of course not the presets. Pros The most that I like it's easy to use, the GUI Nmap is really simple and straight forward. I have used the GUI in the begging and helped me a lot to work faster. And the profiling is even better. Cons It is the same as in the GUI and the command line the output is a bit too messy and difficult for the eye to follow. It's not a big deal since I know each section and what where to expect. It would be great if there was a better structure, Review Source VR Verified Reviewer Leader Used the software for: 2+ years ### "The de facto network scanner" April 21, 2018 5.0 The absolute goto network scanner Pros Nmap is loaded with tons of features and options, including a scripting language to add even more features as needed.

Mi è piaciuto moltissimo il fatto che Nmap può essere personalizzato per adattarsi alle esigenze specifiche dell'utente, con opzioni di scansione e di output configurabili Cons Nmap può essere utilizzato per attacchi informatici e violazioni della sicurezza informatica, quindi può essere considerato una minaccia per la sicurezza delle reti se utilizzato da persone malintenzionate Review Source VR Verified Reviewer Independent Contractor Computer & Network Security Used the software for: 6-12 months ### "Network Mapper" December 26, 2018 4.0 It does not solve any business problems, just helps in monitoring network.

Nmap has made port scanning extremely easy which is one of the initial steps of penetration testing for security engineers. Cons I am aware of only the command line interface of Nmap. There can be a possibility to generate reports based on the reconnaissance activities generated by using Nmap Review Source OEG Oscar Ernesto G. Computer engineer Higher Education Used the software for: 1-2 years ### "Nmap, the best tool to monitor the security of your systems " September 25, 2021 5.0 The absolute ally for computer security Pros This program even in its realistic renditions is extremely incredible, and has alternatives to make filters undeniably challenging to identify by casualties or organization administrators. Output any scope of ports you need and even recognize the casualty's working framework, making the programmer distinguish all the more unmistakably how to get to the far off PC Cons It has no cons, it practically has a tool (Zenmap) that helps you if you don't know how to code, and it has a very detailed user manual. Review Source JO Jose O. College Professor Education Management Used the software for: 2+ years ### "Excellent program of open code that serves to carry out tracking of ports in a computer" March 7, 2018 5.0 highly recommended for people who want to know about hacking techniques Pros This program even in its graphic versions is very powerful, and has options to make scans very difficult to detect by victims or network supervisors. Scan any range of ports you want and even detect the victim's operating system, causing the hacker to identify more clearly how to access the remote computer Cons While it is more complex is the type of scan you want to perform, the scanning process can be slower and take several minutes before the end, the speed of the scan depends basically on 3 factors, speed of the scanner's computer (hacker) , latency in the network (if the network is slow or fast), and speed of response and security measures of the scanned computer (victim) Review Source FQ Fermineduar Q. systems engineer Information Technology and Services Used the software for: 2+ years ### "Excellent tool for mapping and auditing and searching for vulnerabilities in networks" July 11, 2018 5.0 It has allowed me to detect vulnerabilities in the network in a very fast and effective way. like the ports in use in real time and the type of traffic and protocols used by the applications in the company Pros \* It's easy to use. \* It's free. \* Reliable with more than 17 years in the market. \* It has extensive documentation and excellent support from the user community \* Its latest version allows to perform pentesting tasks \* It allows to audit the network to know its vulnerabilities: open ports, connected, wireless and wireless equipment. \* Sneefer functions \* It has multiple security tools that allow audits of passwords, scan the web, exploits, etc. Cons \* It is an excellent work tool for professionals in the area of networks I do not find defects or negative aspects. only that I see it more for advanced users since it runs on linux operating systems and through the use of commands preferably.

Cons Sometimes it can be difficult to use but there is lots of info on the web to help if you are willing to read up on it. Review Source dirath R. bug hunter Computer & Network Security Used the software for: 1-2 years ### "The best open source port scanning tool ever made" October 1, 2019 5.0 it is a critical tool for what i do, so i just love this tool. Pros if this tool didn't exist i would not have found many sensitive data for my job, a bug hunter. It provides a very broad path of information about the target ip, the usage is pretty simple too.. never hestitate using it ever. Cons some times when i have to do a mass scan about some target, it takes longer times Review Source Gabriel T. QA tester Retail Used the software for: 6-12 months ### "Network and security Tool" December 30, 2019 5.0 Nmap is one of the tools always use, great recon on any network with multple options to search from which kind of OS is the target running to options to find vulnerabilities including the CVE if any, a very powerful tool and its also completely free. Pros Easy to use, if you're not used to use it on a shell, you can even use a GUI called zenmap, and runs in every OS, fast depending on the task and with great options, able to export data. Cons Nothing in particular, use it often and its a great tool, the zenmap version the graphic enviroment could improve the controls. Review Source JL Jorge L. IT Consultant Computer & Network Security Used the software for: 2+ years ### "The Standard Network Scanning Tool" October 30, 2018 5.0 Pros I use Nmap very frequently for Information Security Consulting Services and Penetration Testing. It is an invaluable software tool for any information security professional. The level of detailed data you are able to obtain with it is unmatched to similar tools on the market. Cons Thre is nothing to complain about this tool, you can't go wrong with it. However, you do require some background technical knowledge and are required to do a lot of reading to understand how it works. You can use it for a long time and still not take advantage of its full potential. Review Source JP Joel P. IT Administrator Used the software for: 1-2 years ### "The Best and Most Powerful Network Mapping Tool I've Ever Used" June 4, 2018 5.0 Pros We use this software around the office for maping out what IP addresses go to which machines. It tells us the MAC address, tells us what ports are open, closed, what OS the unit is running, and and we can have it specify what range of addresses to look for. We used it to figure out that we had a rarely-used thin client on the network that downloaded a ton of packets (thanks Untangle!) and was being used for non-clinic purposes. It's pretty fast too, our clinic has 20-45 devices on it at any given time, and a complete scan took about 5 minutes. Cons It is a bit utilitarian, which is nice for conservation of resources, but a little more of input information would be nice in the "Target" box. Took a little bit to figure out exactly what to ask for and how. For example, for a range of IP addresses to check, you need to type out your request with a dash, like 192.181.1.1 - 120. It just took a little tinkering. In fact, it has so many EXTRA features, sometimes it can be confusing as well. Review Source GR Guillermo R. University Professor in Telecommunications Enginee Used the software for: 2+ years ### "Versatile open source software very important to find vulnerabilities" May 17, 2018 4.0 Pros \- Easy to use and very quick to use. - Very used in the laboratory practices to carry out the Audits or pentesting. - This tool has allowed students to learn to evaluate the security of the different computer systems. Cons \- You must be aware of the update to try to avoid a failure. - When the scan is more complex it may take longer to do it. Review Source Ben S. IT Consultant Information Technology and Services Used the software for: Less than 6 months ### "Gold Standard Network Scanner" September 26, 2018 5.0 Any person working with or learning about networks should learn and use this. Could not recommend it more! Pros This program is crazy powerful if you have learned the ropes. Lots of professionals rely on it for their job and for good reason. -Free -Extensive track record -Crazy amounts of help for it through documentation and community -Feature Rich Cons Two cons I have noticed when using this software: -There can be a bit of a learning curve for this software, particularly when using command line vs GUI. -Scans can be slow depending on two factors. Type and amounts of scans can make scans slow. Additionally you can set the speed of the scan to remain undetected. This can also slow scans down, but that's to be expected. Review Source Jaikaran S. Developer Information Technology and Services Used the software for: 6-12 months ### "Powerfull Tool" March 5, 2020 5.0 Been great, had an issue with mysql server and turns out there was skype blocking those ports. Pros Finding those vulnerabilities with those open ports in a contained environment, just the perfect choice to do that.

Main pros: - Virtually unlimited scanning options for almost every possible scenario - Scripting engine for automation - Optimized performance - Both command line and GUI interfaces for all tastes Cons I think that adding it's own TCP stack implementation is a huge plus, which will leverage it to supersede softwares like hping and unicorn Review Source AM Alejandro M. support analyst Internet Used the software for: 2+ years ### "The most powerful scanner is here!!"

Easy for testing local and remote networks. The command line is simple enough to use, though most of the time on Windows I will use the GUI. The documentation is also pretty straightforward as it's helps me with some concepts that I should have known. Pros The included Zanmap GUI makes using it pretty straightforward for a beginner with some basic networking knowledge. Cons The GUI, while functional, looks quite old and may be off-putting for some users. However, I'm more interested in the core fiunctionality . Review Source Jonathan G.
