What is Metasploit Framework?

Metasploit is an open-source penetration testing framework used for exploiting vulnerabilities, post-exploitation, and security research. It provides a vast collection of exploits, payloads, and auxiliary modules, making it a go-to tool for ethical hackers and penetration testers.

Metasploit can be used for both red teaming and blue teaming, enabling security professionals to understand, exploit, and defend against real-world threats.
