From IT Intern to Junior Penetration Tester: Madelyn's Story

Job-ready skills

Madelyn was a curious IT intern stuck on routine tickets, fascinated by how systems break but never allowed to find out. Without a formal certification, she built a hands-on offensive toolkit in CertLabz's labs and landed a junior penetration testing role on proven skill alone. Here's how she did it.

Can you tell us what you do now?

I'm a Junior Penetration Tester. I get paid to break into systems, ethically and with permission, and then explain clearly how to fix the weaknesses I find. I was an IT intern stuck on routine tickets, so doing offensive security for a living genuinely feels like a dream. I get to think like an attacker all day and help organizations get stronger. It's the most exciting work I can imagine doing, and I still can't quite believe it's my job.

Where did your journey start?

I started as an IT intern, mostly handling tickets and resets all day. I was endlessly curious about how systems could be exploited, but my role never let me explore any of that. I wanted to test and attack systems, not just maintain them and keep them running. That curiosity needed an outlet, and my day job wasn't giving it one. I knew I had to go and build those skills somewhere on my own.

What made you want to move into penetration testing?

I was fascinated by how things break and, even more, by how attackers actually think. Defending is important, of course, but I really wanted to understand the offensive side deeply. Penetration testing let me channel my natural curiosity into a real, valuable, and in-demand skill. The challenge of outsmarting a system was simply irresistible to me. It felt like the perfect match for the way my mind works.

How did CertLabz help you get there?

CertLabz gave me a safe, legal place to actually attack things and learn. The labs let me practice real techniques in an environment built specifically for it, where breaking things was the entire point. The performance-based questions put me in realistic engagements from reconnaissance all the way to reporting. I learned by doing the actual work a tester does, not by memorizing definitions. That hands-on experience became my real qualification.

"It wasn't a certificate that got me hired. It was demonstrable skill, built in the labs."

Madelyn, Junior Penetration Tester
What skills did you build?

These aren't tools I just read about somewhere; they're tools I used until I was genuinely fluent with them. That practical fluency is exactly what got me hired, even without a formal certificate.

What landed you the role without a certification?

In my case, it honestly wasn't a certification that landed the job, it was demonstrable skill. I could show real, hands-on experience with the exact tools and techniques the role required. When I proved I could actually do the work in front of them, that mattered far more than any piece of paper. My lab work effectively became my portfolio. Employers cared that I could perform, and I could clearly show that I could.

What did you value most about the experience?

What I valued most was being able to learn by actually attacking systems safely. You can't really learn offensive security from a textbook, and CertLabz understood that. The realistic labs let me build true, usable skill rather than surface knowledge. I also loved that it rewarded curiosity and experimentation. That freedom to explore is what made me genuinely good at the work.

What advice would you give someone starting out?

If you want offensive security, you have to get your hands dirty in a safe, legal environment. Learn the real tools by actually using them, not just by reading about them in theory. Build a portfolio of practical work you can point to and talk through. Sometimes proven, demonstrable skill speaks louder than a certificate ever could. Focus on what you can actually do, and let that open the door.

What's next for you?

Next, I'm sharpening my skills in web application and cloud penetration testing, which are areas I find fascinating. I'd eventually like to earn a respected offensive security certification to formalize what I can already do. For now, I'm learning as much as I can on real engagements and from senior testers around me. I also want to contribute to the security community by sharing what I learn along the way. The field never stands still, and neither do attackers, so neither will I. Staying genuinely curious is what makes me good at this work.
