An ethical hacker plays a crucial role in cybersecurity by intentionally probing systems to identify vulnerabilities before malicious hackers can exploit them. These professionals utilize the same techniques as hackers but with permission and for protective purposes. They conduct penetration testing and security assessments, providing companies with insights on potential risks. By simulating real-world attacks, ethical hackers help organizations understand their weaknesses and strengthen defenses. Their work is vital in developing robust security protocols and fostering a culture of cyber resilience within organizations, ultimately protecting sensitive data.
