From Banking to Cyber Security: Meet Caroline

Switching into cyber security doesn’t usually start with a certification plan or a roadmap. Sometimes, it starts with watching something go wrong, repeatedly, and realizing you want to be part of the solution.

That’s how Caroline Liu began her journey from banking to cyber security.After years working with mutual funds and mortgages, Caroline regularly dealt with fraud cases, scams, and phishing attacks. She watched people lose their lifetime savings and resetting accounts stopped feeling like enough. She wanted to understand how these attacks worked, and more importantly, how to stop them.

What followed was a career switch many aspiring cyber security professionals will recognize. Uncertainty, steep learning curves, and moments of self-doubt. But one thing consistently bridged the gap between theory and real-world readiness: TryHackMe.

Choosing Cyber security for the Right Reason

Caroline didn’t switch careers because cyber security was trending. She chose it because it directly connected to problems she had already lived through:

• Financial fraud
• Social engineering
• Phishing attacks targeting vulnerable people

Cyber security gave her a way to move from damage control to prevention. That sense of purpose mattered especially when the learning became challenging. She also wanted a field with a high ceiling:

“Something I could keep growing in for years, not a role I’d outgrow quickly.”

“You Don’t Have an Cyber Background” And Why That Didn’t Stop Her

Like many career switchers, Caroline felt familiar doubts:

• No IT background
• No coding experience
• Too late to start

What she learned early on is something many people underestimate about cyber security: it’s not just about tools, it’s about how you think. Learning how to question systems, spot weaknesses, and understand why things break mattered far more than where she started. That shift turned doubt into confidence.

Where College Stopped and TryHackMe Picked Up

Caroline enrolled in a cyber security diploma program that gave her structure and a strong theoretical foundation. Like most formal programs, it followed a defined curriculum designed to introduce core concepts.

As she progressed, she realised that truly mastering those concepts required more time inside real tools and environments than structured lab sessions alone could offer. After hearing professors and classmates repeatedly recommend TryHackMe, she decided to try it. A few labs in, she subscribed, later calling it:

“The best investment I made that year.”

Why? Because TryHackMe didn’t just explain concepts it put her inside them, helping everything she learned in class finally click.

How She Challenged Herself to Learn Faster

When Caroline first started on TryHackMe, she didn’t approach it casually. She set a clear personal rule:

“At least three rooms per week. No less.”

That structure mattered. It turned learning into a habit. But something unexpected ( actually expected) happened…she quickly fell in love with the hands-on nature of TryHackMe. Three rooms became five and five became more and more. Learning stopped feeling like an obligation and started feeling like progress. TryHackMe became part of her daily habits, alongside her college coursework, reinforcing and expanding what she was learning in class.

Learning What the Classroom Couldn’t Fully Cover

Through TryHackMe, Caroline was able to practice areas that are often difficult to explore in depth within a formal academic setting:

• Realistic phishing scenarios, including building attacks, not just identifying them
• Hands-on experience with tools like SIEMs, beyond memorising definitions
• Progressive difficulty, allowing her to go deeper when curiosity struck

Alongside her studies, she worked through regularly updated scenarios that mirrored how real-world attacks actually happen, and how defenders respond in practice.

From Abstract Concepts to Interview-Ready Confidence

One of the biggest shifts TryHackMe gave Caroline was confidence. Before hands-on practice, cyber security concepts felt abstract ports, alerts, tools, workflows. After working through realistic scenarios, interviews became different.

Instead of saying:

“This is what a SIEM is…”

She could say:

“Here’s how I investigated an alert.”

“Here’s how I handled this type of incident.”

In a job market that often demands experience even for junior roles, TryHackMe gave her the closest possible alternative to real-world exposure and experience, something tangible she could explain, justify, and defend in interviews.

The Role of The TryHackMe Community

One thing Caroline didn’t expect but deeply valued was the TryHackMe community.

Instead of competition or gatekeeping, she found:

• People openly sharing write-ups and methodologies
• Supportive discussions on TryHackMe rooms and challenges
• Learners helping each other improve, not trying to “out-rank” one another

“For a career switcher, that environment matters. Learning cyber security can be isolating especially without a technical background. Having a community that encourages progress rather than perfection made it easier to stay consistent and keep going”

Why She Chose Blue Team and Why Career Switchers Should Pay Attention

Like many beginners, Caroline initially thought Red Teaming looked more exciting. But through mentorship and experience, she realized that starting with Blue Team (defensive security) made more sense.

Blue Team work helped her:

• Understand how attacks really unfold
• Learn how systems behave under pressure
• Think like an analyst, not just a tool user

From there, switching into Red Team, GRC, or leadership roles becomes easier not harder. Blue Team gave her a wide foundation instead of a narrow specialization too early.

The Full-Circle Moment: From Learner to Intern at TryHackMe

Perhaps the most powerful part of Caroline’s story isn’t just that TryHackMe helped her learn. It’s that after starting with zero IT or cyber background, setting weekly learning goals, and committing to hands-on practice, she’s now an intern at TryHackMe.

From learner to career switcher to practitioner-in-training to contributing to the platform that helped her get there. That full-circle moment didn’t happen because of shortcuts. It happened because of consistency, hands-on learning, and community support.

Final Thought: Why This Matters for Career Switchers

Caroline’s journey shows what many people need to hear:

You don’t need to know everything to start. You are never “too late to start”. You don’t need to feel ready. For her, TryHackMe wasn’t just a learning platform it was:

• The bridge between theory and real-world practice
• A supportive community that made learning less intimidating
• The best investment she made during her career switch

And eventually, it became part of her story not just as a learner, but as someone now helping others learn too.
