Kali Linux vs. Metasploit vs. Nmap

Kali Linux is especially well suited in environments where high security is needed for your custom developed applications. This is well suited for offensive testing your high security in house developed applications. It is also very good for doing penetration testing on in house developed applications and safe guarding them from external attackers. Kali Linux is tough for use as a day to day Linux operating system as this was never intended to be used by beginners and occasional Linux users.

It is easy to use with sufficient documentation on how to use the tools for end users or newbies. Experienced testers will find it easy to customise and configure the test cases. Just wished that I could have taken up a course on using this tool in my study days so that I could had explored more and improved my familiarity with the tool, unlike when working where access and time to explore the other features of the tool is limited

If you're a sysadmin, or anyone who's had to deploy network services, you've almost certainly had to use Nmap at some point or other. Need to see what devices are on your LAN? Nmap can tell you that. Want to check which ports your web server has open to the internet? Nmap is your friend.

Nmap is a powerful command-line tool and has many options that require some reading of documentation to get the best out of (although generally straightforward). If the thought of working at the command-line scares you (presumably not if you're reading this review), then you may want a much simpler tool, or at least check out Zenmap GUI.

• 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.

• The GUI version on Nmap could use some improvement with the options that are available to do scans. For example, they could make it easier to select options for the different types of scanning for people who are beginners
• There are no abilities to schedule a scan in the Nmap tool.
• An intensive scan sometimes takes too much time to complete.

Nmap uses are very practical and I don't think there is a better tools for what Nmap does. It is open-sources that therefore there is no cost to use it. It offers a number of benefits, including but not limited to network mapping, port scanning and more. It is very reliable as a network scanning tool.

There is a very large support community and a robust selection of add-ons and scripts. Once you get the use down this is one of the most powerful tools and you can find anything you are looking for as far as examples on the web. While not having official support its not lacking by any means.

Metasploit is the most well-known tool in the average pen tester's toolkit. It's hard to compare to its neighbor's due to its size and following.

Alternatives to Nmap (other IP scanners) are often much more limited in what they can do; They often only allow you to scan a specific subset of ports or a limited number of IP addresses in one command. Nmap is unrestricted in that regard. What makes Nmap stand out above the rest, is the complete network analysis package you get with it. It allows IP scanner, network deep-dives, hardware analysis, vulnerability analysis, encryption detailing, and so much more, in one free application

• Nmap with Wireshark is free, so it's been a great combo team to gather info and test.
• It's allowed us to avoid fines from false positives and to fix actual issues ourselves.
• Great for finding hosts, helps keep the network secure.
