Nmap 7.80

You can use this utility to scan your network for vulnerabilities and fix potential issues that might be exploited. It is a tool intended for network administrators who need it to monitor the inventory, make upgrades when it’s necessary, receive alerts when computers are down, etc.

Here are the key features:

• You’ll receive detailed reports based on raw IP addresses about the operating system installed, what programs are available on the remote computers, the status of the firewalls, etc
• As the name suggests, Nmap (Network Mapper) will map all the computers available on the network, no matter the obstacles (firewalls, routers, filters, etc)
• Can handle hundreds of thousands of machines
• Support for detecting all major operating systems (Windows, Linux, Solaris, Mac OS X, Sun OS, OpenBSD, FreeBSD, to name but a few)
• You have access to both the regular version and command line, particularly useful if you want to integrate Nmap with other utilities or want to run it in batch mode
• Although it’s probably not the right tool for someone who’s not very technical, it has excellent support files
• It has received numerous awards and nowadays comes packed with several operating systems (Redhat, Debian, OpenBSD, FreeBSD, etc)
• It is open source, so people around the world contribute to make it better every passing year
