Rapid7

Hudson Rock offers a partner program to MSSPs and other technology vendors. To date, Hudson Rock has partnered with Rapid7, Kovrr and other cybersecurity companies.

Metasploit is an open-source computer security project maintained and developed by Rapid7. It includes a set of tools that can help a cyber security analyst of an organization to find some bugs in their system and recommend some potential ways to solve them. It usually comes pre-installed in Kali Linux. It contains over 590 sets of modules that are essentially useful. Some of the Important ones are mentioned below

Above is a somewhat extensive list that should cover you. Rapid7 can also be configured to send you notifications IIRC.

I cannot comment on price, as I do not foot the bill (I am not on the InforSec Team!), but where I work we use Rapid7. It is on Windows, Linux, macOS, servers,...

1-) Learn Hacking on a debian based distro like Kali Linux - I personally started with tools like nikto, camhacker... and then moved to more complex frameworks like metasploit.

I once had to give a presentation about Metasploit, and whether it was ethically correct for the creator to make it free and open-source, available to everyone. And in researching this I realized that there were a lot of parallels between the arguments for or against hacking tools being readily available and the arguments for or against gun control. I'll just list a few quickly:

Metasploit Framework (mentioned earlier)

This phase is where the pen testers practically prove that there exist potential vulnerabilities in the target system. The pen testers do the hacking using an array of technical approaches and social engineering methods to exploit the vulnerabilities. The ethical hackers commonly use Metasploit framework to automatically execute exploitation against the target systems. Moreover, they may install malwares such as rootkit to persistently maintain their foothold and further compromise the target system.
