History

Kali Linux was released in 2013 as the successor to BackTrack, a popular penetration testing distribution. It was developed by Offensive Security, the company behind the OSCP (Offensive Security Certified Professional) certification.

Since its inception, Kali Linux has become the de facto standard penetration testing distribution, used by security professionals, ethical hackers, and cybersecurity teams worldwide.

Today, Kali Linux continues to evolve with regular updates, new tools, and enhancements that keep security professionals equipped with the latest capabilities for conducting authorized security testing and research.
