In today’s dynamic digital landscape, robust cybersecurity measures are more crucial than ever. With cybercrime and data breaches on the rise, top ethical hackers have emerged as key players in defending against malicious attackers. These skilled professionals possess the technical expertise and ethical code of conduct necessary to identify vulnerabilities in computer systems, networks, and applications, and to bolster their security.

What is Ethical Hacking?

Ethical hacking, also known as penetration testing or white hat hacking, is the practice of testing computer systems, networks, or applications for security vulnerabilities in a controlled and lawful manner. Ethical hackers use the same techniques as malicious hackers to identify and exploit weaknesses in a system’s defenses, but their purpose is to uncover and fix security flaws rather than to cause harm. The goal of ethical hacking is to proactively identify and address security risks before malicious actors can exploit them.
