MASSCAN - TCP port scanner, spews SYN packets asynchronously, scanning entire Internet in under 5 minutes

•    C

MASSCAN is Mass IP port scanner. This is the fastest Internet port scanner. It can scan the entire Internet in under 6 minutes, transmitting 10 million packets per second. It produces results similar to nmap, the most famous port scanner. Internally, it operates more like scanrand, unicornscan, and ZMap, using asynchronous transmission. The major difference is that it's faster than these other scanners. In addition, it's more flexible, allowing arbitrary address ranges and port ranges.

Zeus-Scanner - Advanced reconnaissance utility

•    Python

Zeus is an advanced reconnaissance utility designed to make web application reconnaissance simple. Zeus comes complete with a powerful built-in URL parsing engine, multiple search engine compatibility, the ability to extract URLs from both ban and webcache URLs, the ability to run multiple vulnerability assessments on the target, and is able to bypass search engine captchas. Running without a mandatory options, or running the --help flag will output Zeus's help menu: A basic dork scan with the -d flag, from the given dork will launch an automated browser and pull the Google page results: Calling the -s flag will prompt for you to start the sqlmap API server python sqlmapapi.py -s from sqlmap, it will then connect to the API and perform a sqlmap scan on the found URL's.

The full set of options available to you are as follows.

furious - Golang IP/port scanner with SYN (stealth) scanning and device manufacturer identification

•    Go

Furious is a fast, lightweight, portable network scanner. I haven't done any proper performance testing, but a SYN scan of a single host, including all known ports (~6000) will typically take in the region of 4 seconds. On the same machine, nmap took 98 seconds and produced exactly the same results.
