Cybersecurity isn’t just a buzzword anymore — it’s one of the fastest-growing career fields in the world. Organisations across every industry are investing heavily in digital defence, creating opportunities for people from a wide variety of backgrounds to step into the field.
But if you’re starting in 2025 with no cybersecurity background, how do you realistically make the switch? The good news: it’s not only possible, but more accessible than ever thanks to hands-on labs, structured learning paths, and AI-powered support tools like Echo.
This guide will walk you through the steps to transition into cybersecurity — even if you’re starting from scratch.
Why cybersecurity careers are worth pursuing in 2025
- High demand: Security teams are hiring across industries, from finance to healthcare to tech.
- Diverse roles: Red team (offence), blue team (defence), incident response, digital forensics, SOC analyst — there’s a niche for different interests and strengths.
- Upward mobility: Entry-level jobs can quickly lead to more advanced positions, especially if you can demonstrate practical skills.
- Global opportunity: Cybersecurity roles are borderless — companies recruit talent remotely, opening doors worldwide.
Step 1: Build your technical foundations
Before you dive into hacking or defending systems, get comfortable with the basics:
- Networking (TCP/IP, firewalls, VPNs)
- Operating systems (Linux and Windows)
- Command line navigation
👉 TryHackMe’s Pre Security Path is built for complete beginners and covers exactly these fundamentals.
Step 2: Explore cybersecurity specialisations
Not every role requires the same skills. A few common paths:
- Offensive security (Red Team / Penetration Testing): Learn how attackers exploit systems.
👉 Jr Penetration Tester Path - Defensive security (Blue Team / SOC Analyst): Monitor, detect, and respond to threats.
👉 SOC Level 1 Path - Digital Forensics & Incident Response (DFIR): Investigate breaches, recover evidence, and strengthen systems.
👉 DFIR module
Exploring these areas early helps you see where your strengths and interests lie.
Step 3: Practise hands-on with real-world labs
Reading theory won’t get you job-ready. Employers want proof you can do the work. Virtual labs let you:
- Hack into simulated machines safely.
- Analyse attacker behaviour in SOC-style environments.
- Investigate forensic cases with real tools.
👉 Labs like Hacktivities provide fresh challenges to keep your skills sharp.
Step 4: Learn continuously with AI support
One of the biggest barriers to switching careers is getting stuck. In 2025, AI tools like Echo, TryHackMe’s learning assistant, help break through those barriers by:
- Giving contextual hints when you’re stuck in a lab.
- Explaining complex concepts in plain language.
- Helping you connect lab exercises to the bigger picture.
This kind of instant support keeps you motivated and progressing.
Step 5: Build your portfolio
Employers don’t just want certificates — they want evidence of skills. Build credibility by:
- Writing lab reports or walkthroughs on GitHub or a personal blog.
- Sharing what you’ve learned on LinkedIn or cybersecurity forums.
- Contributing to CTFs and documenting how you solved challenges.
Even simple writeups show employers you can communicate findings clearly, which is as valuable as technical ability.
Step 6: Target entry-level roles and certifications
Some common entry points include:
- SOC Analyst
- Junior Penetration Tester
- IT Security Support
- Incident Response Analyst
Certifications can help if chosen wisely. For beginners, CompTIA Security+ remains one of the most accessible — especially if combined with hands-on practice. For more advanced learners, certifications like eJPT or OSCP may be worth exploring later.
Step 7: Apply strategically
Don’t shotgun your CV everywhere. Instead:
- Tailor your applications to highlight practical lab experience.
- Emphasise transferable skills (problem-solving, communication, IT fundamentals).
- Look for companies offering graduate schemes, apprenticeships, or junior analyst positions.
Final thought: From beginner to cyber professional
Transitioning into cybersecurity in 2025 isn’t about racking up theory. It’s about proving you can solve problems in realistic environments. With structured learning paths, hands-on labs, and AI support, anyone motivated can make the leap — whether you’re coming from IT, a non-technical role, or university.
