How to Get Into Cyber Security With No Experience

“You need experience to get the job, and a job to get the experience.” Cyber security has a reputation for that catch-22 — but it’s actually one of the most realistic technical careers to break into without a degree, precisely because the UK has more roles than trained people to fill them. What it takes isn’t luck; it’s a deliberate path: the right foundations, a recognised certification, hands-on proof you can do the work, and a sensible first role that gets your foot in the door. Here’s how to build that from a standing start.

Can you really get in with no experience?

Yes — but not by jumping straight to “hacker.” Employers hiring at entry level aren’t expecting a portfolio of breached systems. They want someone who understands how IT works, thinks methodically under pressure, and has proven they’ll put the hours in. Cyber security is a well-documented shortage skill in the UK, and most people who land a first role came from adjacent jobs — IT support, service desk, networking, even admin — rather than a computer-science degree. If that’s you, you’re closer than you think; you just need to package it and fill the gaps in the right order.

Start with the IT foundations (don’t skip them)

The biggest mistake career-changers make is chasing cyber tools before understanding the systems those tools protect. You cannot secure a network you don’t understand. Before anything security-specific, get genuinely comfortable with the basics of how computers, operating systems and networks work. In practice that means:

• CompTIA A+ — hardware, operating systems and troubleshooting (the bedrock of any IT role).
• CompTIA Network+ — how networks are built and how traffic actually moves.
• Then CompTIA Security+ — the entry-level cyber certification that sits on top.

If you’re not sure how these stack together, our guide to CompTIA stackable certifications lays out the order.

Get a recognised certification — the CV door-opener

At entry level, employers can’t judge you on experience, so they lean on certifications instead. CompTIA Security+ is the one most UK entry-level cyber adverts ask for by name — it proves you understand core security concepts, and it’s what gets a career-changer’s CV past the first filter. Free resources like Professor Messer’s videos are excellent for revision, but pair them with a structured Security+ course when you want the exam pass and the certificate on your CV, not just the knowledge in your head.

Build hands-on proof

A certificate says you know the theory; a lab says you can do the job — and the second is what separates candidates who get interviews from those who don’t. You can build all of this for free at home:

• TryHackMe and Hack The Box — guided, beginner-friendly paths that teach real skills in a browser.
• LetsDefend or Blue Team Labs Online — if you’re aiming at defensive/SOC roles (where most first jobs are).
• A home lab — spin up a Windows and a Linux virtual machine with VirtualBox or VMware, and practise. Learn to read logs, use Wireshark, and get familiar with a SIEM (Splunk has a free tier).

Then write it up. A short blog or a simple GitHub page describing what you built and what you found turns “I studied for Security+” into “here’s a suspicious login I investigated and how.” That evidence is gold in an interview.

Get real-world experience — the piece most people miss

This is where the catch-22 actually bites, and it’s the part certifications alone don’t solve. Two routes work:

1. Start adjacent, then move across. A service desk or IT support role is the classic on-ramp: you’re already inside the environment, and you can move into a SOC or security-admin role internally within a year or two. Volunteer for anything security-flavoured — patching, access reviews, incident triage — and make your interest known.
2. Use a structured “into-cyber” pathway. Programmes built specifically to close the experience gap can fast-track this. Cerco’s Cradle to Cyber programme is a good example: IT foundations, then 6–12 months of paid, real-world experience as an IT service engineer, then practical cyber training (SIEM, threat hunting, incident response) — so you finish with verified industry experience, not just a certificate. Routes like this exist precisely because employers want people who’ve done the work, not only read about it.

Make your CV and LinkedIn speak cyber

Reframe what you’ve already done in security language, and put your certification and labs near the top where they get seen. Use the words the adverts use — Security+, SIEM, incident response, vulnerability management — so both the hiring manager and the CV-screening software recognise you. Set your LinkedIn headline to something like “Aspiring SOC Analyst · CompTIA Security+ · home-lab projects,” follow the people who hire, and post the write-ups from your labs. It signals momentum, which is exactly what employers look for at entry level.

Target the right first roles

Don’t apply for “Cyber Security Analyst, 5 years required” and get disheartened. Aim at the genuine entry points: SOC Analyst (Tier 1), IT Security Administrator, Junior Security Analyst, and service-desk roles with security duties. It helps to know where the demand is concentrated — our roundup of the industries hiring for cyber security skills is a useful steer. And network: the TryHackMe Discord, r/cybersecurity, and local BSides events fill a lot of first roles that never hit the job boards. It’s also worth setting up alerts on a specialist board like Cyber Security Jobsite so entry-level roles come to you.

Nail the interview

Entry-level interviews test attitude and structured thinking, not war stories. Have two or three examples ready in STAR shape — Situation, Task, Action, Result — and be ready to walk through your labs out loud: what you set up, what you looked for, what you’d do next. Show curiosity and a genuine learning habit. At this level, that’s what gets the offer.

What it pays — and where it leads

The numbers: the median UK cyber security analyst salary is around £55,000 (rising to about £70,000 in London), and it climbs steeply from there into senior and management roles.
