A few years ago, practicing what we learned about hacking/cybersecurity/pentesting wasn't an easy task, as there were no environments or labs that simulated vulnerable systems. Consequently, professionals or students who went through that time often had to create their own simulation environments or even conduct tests on applications and systems of companies without authorization.
However, with the advancement of technology and the growth of cybersecurity companies like HackerSec, it is now possible to learn cybersecurity and practice in real, controlled, and authorized environments.
