#ZENMAP ALTERNATIVE FREE#
This method detailed below will get you a network view and is very simple to do with a widely used, free tool called Zenmap.

It’s important to know how to see all those devices at the network level.

ZMap has also been used to detect vulnerabilities in universal plug and play devices and search for weak public keys in HTTPS website logs.
#ZENMAP ALTERNATIVE SOFTWARE#
One of the developers of ZMap, Zakir Durumeric, used his software to determine a computer's online state, vulnerabilities, operating system, and services. The application has been used for port 443 scans to estimate power outages during Hurricane Sandy in 2013. ZMap can be used for both vulnerability detection and exploitation. This results in about 2% of IP addresses being missed during a typical scan, but when processing billions of IP address, or potential IoT devices being targeted by cyberattackers, 2% is an acceptable tolerance. ZMap also speeds up the scanning process by sending a probe to every IP address only once by default, whereas Nmap resends a probe when it detects a connection delay or fails to get a reply. This process ensures that once ZMap starts sending probes out to different IPs, an accidental denial of service could not occur because an abundance of transmissions would not converge on one subnet at the same time. Building the initial list of numbers for every IP address takes upfront time, but it is a fraction of what is required to aggregate a list of every sent and received probe. The ZMap software takes every number from 1 to 2 32-1 and creates an iterative formula that ensures that each of the possible 32-bit numbers is visited once in a pseudorandom order. In contrast, ZMap uses cyclic multiplicative groups, which allows ZMap to scan the same space roughly 1,300 times faster than Nmap. As replies return, Nmap compiles them into a database to keep track of responses, a process that slows down the scanning process. Nmap sends out individual signals to each IP address and waits for a reply. ZMap iterates on techniques utilized by its predecessor, Nmap, by altering the scanning method in a few key areas.
