What is a security tester?

Security testers, also known as penetration testers or ethical hackers, are professionals who assess the security of computer systems, networks, and applications. They simulate cyberattacks to identify vulnerabilities that malicious hackers could exploit. Their work helps organizations strengthen their defenses by discovering and addressing security weaknesses before they can be exploited. Security testers use a variety of tools and methodologies to conduct their assessments and often provide detailed reports with recommendations for improvement.
