This is one if the best cybersecurity training courses you can take. Offensive Security's training courses focus on offensive security, specifically the field of penetration testing. Due to the large number of specializations from the information security domain, the most suitable course for you depends on what you are interested in.
The Offensive Security, Penetration Testing with Kali Linux (PwK) course focuses on modern techniques used by penetration testers all across the globe, so it would be a great start for you.
Cracking the Perimeter (CTP) focuses on exploit development, web application, and WAN attacks, which are also useful for pentesters; however, PwK teaches you the core skills that are required to be a good pentester. CTP also requires advanced knowledge of different offensive techniques, so it is not recommended for beginners. If you feel you possess the required knowledge to take it, feel free to try the following CTP course-registration challenge: http://www.fc4.me/.
In addition to PwK and CTP, they also have a course devoted to wireless penetration testing, Offensive Security Wireless Attacks (WiFu).
