Cyber security is one of the fastest-growing job sectors in the UK and it’s not hard to see why. In this article, we explore how to get into cyber security.
Recent high-profile hacks have served to highlight that businesses are under constant threat from cyber attacks and consequently, they need skilled people to keep their systems safe.
That means opportunities are booming, salaries are competitive and you don’t always need a traditional degree to get your foot in the door.
This is a well-established industry. In fact, the UK cyber security sector generated £13.2 billion in revenue in 2024, reflecting a 12% increase from the previous year, according to the Department for Science, Innovation and Technology.
Further growth is expected, meaning more jobs, more training opportunities and more room for career changers to make their move.
So if you’re wondering how to get into cyber security – whether you’re a graduate, a career changer, or someone with a keen interest in tech – here’s what you need to know.
Think of cyber security analysts as the digital bodyguards of the modern workplace.
Day to day, a cyber security analyst might be investigating security alerts, helping set up firewalls, or even training colleagues on how to avoid risky behaviour, like clicking on dodgy email links.
There’s no one-size-fits-all route into cyber security, which is good news if you’re not coming from a traditional tech background.
Some people start out in general IT or tech support roles, learning the ropes before moving into security. Others come through graduate schemes or apprenticeships, especially in large companies or government agencies.
Then there are those who teach themselves. Thanks to a growing number of online resources, you can build up your skills through virtual labs, free courses, and cyber competitions – without ever setting foot in a lecture hall.
For people looking to retrain, there are funded programmes like Skills Bootcamps that offer fast-track cyber training in just 8 to 16 weeks.
The key is to show employers that you understand the basics and have the mindset to solve problems under pressure.
Not necessarily – but having the right certifications can make your CV stand out.
If you’re just starting out, look into beginner-friendly options like:
For those further along, certifications like CISSP or GIAC show a deeper understanding of security systems and leadership.
And if you do prefer the academic route, some universities offer cyber security degrees or master’s programs, both in-person and online.
Whatever route you take, employers will want to see proof that you’ve got practical skills – not just theory. CV writing is going to be key here to ensure you demonstrate the appropriate balance.
While qualifications help, hands-on experience always counts.
If you’ve worked in IT support, networking, or systems administration, you’re already halfway there. You understand how systems work – which means you can spot when something’s wrong.
Don’t have direct experience? No problem. Try building your skills in simulated environments like TryHackMe, Hack The Box, or even open-source projects.
These platforms let you explore real-world security scenarios in a safe way, and many employers value that kind of self-motivation.
Internships, volunteer roles, or bug bounty programs can also give you something to talk about at interviews.
You might also consider joining professional networks like (ISC)² or BCS, which can offer mentoring, training, and a foot in the door.
Entry-level cyber security analysts in the UK can expect to earn between £25,000 and £40,000 per year according to CyberArrow.
An entry-level cyber security analyst salary depends on things like your qualifications, location, and employer. In London, where demand is high and costs are steeper, starting pay tends to be higher.
With a few years of experience, mid-level analysts can see their salaries rise to £45,000–£72,000, especially if they pick up in-demand certifications or take on more responsibility.
And at the top end, senior analysts with advanced skills and leadership roles can earn between £65,000 and £80,000, and sometimes more in bigger companies or specialist roles.
Roles like penetration tester, incident responder, or security architect often come with salaries of £80,000 to £100,000+, particularly if you’ve got niche expertise like cloud security or digital forensics.
It’s not just about salary, either. Many roles offer solid benefits – think remote work, training budgets, and generous pensions – especially if you go down the public sector route.
