How to Become a Certified Penetration Tester?

Introduction

Penetration testing is one of the most exciting and rewarding careers in cybersecurity. A certified penetration tester is a professional who simulates real-world cyberattacks to identify vulnerabilities in systems, networks, and applications before malicious hackers exploit them. Becoming certified in this field not only validates your technical skills but also demonstrates your commitment to ethical hacking practices, which can open doors to high-paying cybersecurity roles across industries.

What Does a Penetration Tester Do?

A penetration tester, often called an ethical hacker, evaluates the security posture of systems using authorized simulated attacks. They identify weaknesses, exploit vulnerabilities responsibly, and provide remediation advice to strengthen defenses. Penetration testers use a combination of manual techniques, automated tools, and creative problem-solving to stay ahead of evolving threats.
