If you're searching for how to become a penetration tester, how to become a pen tester, or how to become pentester, this guide will help you understand the exact steps to begin in 2026—even if you’re starting from zero.
Whether you’re a student, IT professional, or career switcher, the roadmap remains achievable with the right skills, tools, and certifications.
What Does a Penetration Tester Do? Key Roles & Responsibilities
A penetration tester (also known as an ethical hacker or pen tester) simulates cyberattacks on systems, networks, and applications to find weaknesses. The goal is to fix vulnerabilities before real hackers exploit them.
Core Responsibilities Include:
Performing simulated attacks on websites, servers, mobile apps, and networks
Identifying security flaws using tools like Burp Suite, Nmap, and Metasploit
Reporting vulnerabilities to security teams or clients
Documenting findings in detailed penetration testing reports
Working with IT and development teams to patch issues
Staying updated with the latest cybersecurity threats
Pen testers think like hackers but act ethically. This makes their work both strategic and technical.
