Masscan alternatives

Although there are many port scanning utilities, sometimes it is specific functionality that makes a tool really powerful. For example, QuickScan saves the results of a scan, which then can be processed later for follow-up.

Zenmap is a graphical user interface (GUI) for Nmap. It can be of great help to start a network scan by simply selecting the options you want. Besides Linux, it also runs on Microsoft Windows, macOS, BSD, and other flavors of Unix.

One of the strengths of Zenmap is the ability to store profiles, which can be reused for later scans. The command creator is another one, which helps interactively create the right nmap commands. Recent scans are stored in a searchable database and scan results can be saved and compared.

This small utility can retrieve information from the WHOIS database, to see who owns an IP address or domain name. Besides that, it can obtain information from the system itself, like the uptime. DMitry also has the option to search for email addresses, perform a TCP port scan, and use modules specified by the user.

Nmap is short for "Network Mapper". It is a free and open source utility for network discovery and security auditing. It was release in September of 1997 by Gordon Lyon, commonly known under his pseudonym "Fyodor".

Leviathan is a security tool to provide a wide range of services including service discovery, brute force, SQL injection detection, and exploit capabilities. The primary reason to use this tool is to do massive scans on many systems at once. For example to include a huge network range, country-wide scan, or even full internet scan.

Portspoof is a small utility with the goal to make port scanning by other much harder. It achieves this by showing all configured TCP ports to be in the 'open' state instead of closed or filter. The related ports are also emulating valid services. This way a port scan on the system will reveal many open ports and look to have legitimate services running.
