An ethical hacker, also known as a white-hat hacker or a penetration tester, is a cybersecurity professional who specializes in identifying vulnerabilities and weaknesses within computer systems, networks, and applications. Unlike malicious hackers (black-hat hackers) who exploit these vulnerabilities for personal gain or harm, ethical hackers use their skills and knowledge to help organizations fortify their digital defenses. They engage in legal and authorized hacking activities, conducting thorough assessments and simulated attacks to uncover security gaps. 

By simulating real-world cyber threats, ethical hackers play a critical role in preemptively identifying and addressing potential risks. Their work is instrumental in safeguarding sensitive information, maintaining the integrity of digital assets, and ensuring the overall security posture of businesses and institutions in an increasingly interconnected and technologically reliant world. Ethical hackers are valued for their expertise, dedication to cybersecurity ethics, and their pivotal role in enhancing the resilience of digital infrastructures.
