Reviews
(1-17 of 17)- Comprehensive port scanning of both TCP and UDP ports.
- Clever 'interrogation' of services listening on open ports. It will use all sorts of techniques to try and work out what service is listening on a port, and potentially even version and host information, etc.
- Very configurable. You can choose exactly what you want to scan for, limit to port ranges, protocols, IPs, etc.
- Very scriptable. Being a command-line utility (check out Zenmap if you want a GUI), you can call it from your own scripts, automation pipelines, etc.
- Not a problem with Nmap, per se, but the related Zenmap GUI could do with some love! It does the job perfectly well so I shouldn't complain, but it would benefit from a modern makeover.
- It is open source, so you can verify how it works
- It is very extensive, with lots of advanced networking features
- It is very lightweight and easy to start up
- The learning curve is quite steep
- On Windows, not all functions are available
- If you do not limit your scan range, a command can take a really long time to complete
- Scanning multiple IPs for open ports
- very lightweight and not heavy
- First step in auditing, pentesting, etc.
- Bit of a learning curve
- Syntax can be confusing
Also, when we set up a new product or do a proof-of-concept of a software we're looking into, we like to scan it and see what ports may be used and open and then bring it up with our sales engineers.
General review of Nmap
- Nmap is fast and flexible, It allows me to perform custom scan across my network(s)
- Nmap provides crucial OS information when possible
- comes in GUI and command-line versions
- allows me to scan individual IP, ranges and full subnets
- The ability to throttle the scan progress helps me to avoid triggering alarms
- exporting, There's a serious lack of ability to export the information in a readable format to present to VPs and such. I always find myself doing a lot of data massaging to get it in a pretty format
- some scans can trigger sensitive IDS/IPS
- SYN scans can be particularly aggressive and cause problems on remote systems.
Exporting the results from these scans do not always format nicely when imported into spreadsheet programs. much data manipulation is required.
Nmap, best network discovery tool.
- Ease of use
- Completeness
- Good interface
- Lots of options
- Curve of learning
- Fluent design
- Better docs
Nmap is the basis for all other scanners
- Nmap is great at finding live hosts on the network
- Nmap is great for teaching new cyber specialist how network reconnaissance works
- Nmap is built into every major recon tool on the market, it just works when it comes to scanning
- There could be more built in tools for further vulnerability scanning
- command line Nmap should store recent scans automatically
- More detail in the help menu for what some of the triggers actually do
The best hacking tool you will ever need!
- Very user-intuitive.
- Built-in scripts allow for vulnerability testing.
- Better GUI for ZenMap.
- Can be difficult to learn and master.
Brilliant tool for occasional network scanning.
- It's quick (and depending on the options and your preferences for scanning can be made to run even quicker)
- Huge amount of options
- User community support is ubiquitous
- Hardly anything to mention
NMAP is an absolute MUST for any sysadmin!
- Open port scanning is a great tool to ensure your internal and external networks are secured.
- being able to identify endpoints and ensuring they are configured correctly.
- Great to be able to script within NMAP. It truly can be tailored to your exact needs
- Wish it had a gui and a better UI experience.
- Even though it's free an enterprise support option would be great.
You should already be using Nmap
- Highly accurate endpoint identification
- Vulnerability scanning is detailed and clear.
- Easily scripted and analyzed
- CLI only; there is an unofficial graphical interface (but it isn't too great)
- Not supported by a vendor
- Somewhat steep learning curve
Nmap is a great tool for any network admin
- Detects open ports
- IDs hosts
- Checking firewall rules
- Maybe take some of the features of Zenmap and bake them in?
- Include fancy extra graphical results charts or graphs or something to show people who you want to convey info too but have no idea what Nmap is actually doing.
- I don't really think I'd change a lot actually.
Network mapper for finding the open ports
- Nmap is an network mapper
- Finding the open ports is very easy using the Nmap
- I recommended this tool all the other employees .
- If there is no network we cannot use this tool
- I recommended to use this tool
Nmap to the stars
- The GUI is very helpful for those that don't like the classic way.
- Intensive Scan, Ping and port scans
- Make a little topology of the Host found.
- Does not work all the time depending on the network and the security on it.
- Network monitoring
- Port Scanning
- Service enumeration.
- It works perfectly as it is where features are concerned. If it is combined with Zenmap for those preferring a GUI, it's invaluable.
Nmap
- Scans for open ports, giving you the option of how aggressively or lightly to scan.
- Can help determine which OS and services are running on a device, again, giving the option of how aggressively to scan a device.
- There is something of a learning curve in using the tool. A number of shortcuts and GUI options are available in Zenmap to simplify the process, but perhaps a more visual interface can help simplify the selection process prior to executing the Nmap command.
Nmap - Get the IP address you need
- Nmap allows you to search IP ranges that you as the user determine
- Nmap gives you a detailed list of utilized IP addresses in the range that you have identified
- Nmap provides what type of device is utilizing an IP address
- When scanning, you have to put in the exact numbers for it to scan, which can be annoying
- Nmap is very simple and just pings IP ranges, I wish it could do more
NMap is your network security blanket. Literally.
- NMap provides a very fast and a very thorough network "sweep" that allows you to quickly map out exactly what's on your network.
- NMap is highly configurable. The "canned" choices are very good in most instances, but using various switches and options, you can create a very specific scan and get exactly the results you're looking for.
- NMap is easy to use. Even a new administrator will be able to use the graphical version (Zenmap) with efficiency right away.
- Running stealthier scans would be a bonus. Current scans are pretty noisy.
- Scans run fast, which sometimes can make it look like a system is being attacked. There is a slow, comprehensive scan option, though.
- NMap scripts are written in Lua, which is not a mainstream language.
