A White Hat hacker, also known as an ethical hacker, is a cybersecurity professional who uses their skills to help organizations protect their systems and data. They identify vulnerabilities in software and networks by simulating cyberattacks, allowing companies to fix these weaknesses before malicious hackers can exploit them. White Hat hackers often work in collaboration with organizations, following legal and ethical guidelines. They may hold certifications such as Certified Ethical Hacker (CEH) or Offensive Security Certified Professional (OSCP) to demonstrate their expertise. Their work is crucial in maintaining the security and integrity of digital information.
