How to Start a Career in Cybersecurity in the UK

Cybersecurity is becoming an important career choice for people who enjoy technology, problem-solving and protecting information. You do not necessarily need years of experience to start. There are several routes into the industry, including entry-level IT roles, apprenticeships, university courses, professional certifications and self-directed projects.

If you are considering a cybersecurity career in the UK, the first step is to understand what employers actually look for and which route fits your current skills.

Why Choose a Cybersecurity Career in the UK?

Almost every modern organisation depends on computers, networks, cloud services and digital information. That creates a need for people who can help protect systems, identify risks, investigate incidents and improve security.

UK government labour-market research estimated that around 143,000 people were working in cyber security roles across the UK economy in 2024, with an estimated workforce gap of about 3,800 professionals. The same research also found that only 17% of core cyber security job postings in 2024 asked for candidates with less than one year of experience, showing why practical evidence can be important for beginners.

Cybersecurity is also a broad field. You do not have to choose one specialised role on day one. You can begin with a general IT or security position and specialise as your knowledge and experience grow.

What Does a Cybersecurity Professional Do?

The exact work depends on the role. A security analyst may monitor alerts and investigate suspicious activity, while a security engineer may help design and maintain technical controls. Other professionals work in penetration testing, cloud security, incident response, risk management or governance.

Common Cybersecurity Career Paths

• Security Analyst: Monitors security events, investigates alerts and helps respond to threats.
• Security Engineer: Helps build, maintain and improve security systems and controls.
• Penetration Tester: Tests systems and applications for weaknesses using authorised security testing.
• Incident Response Analyst: Helps organisations investigate and respond to security incidents.
• Cloud Security Specialist: Focuses on protecting cloud infrastructure, accounts, data and services.
• GRC Professional: Works with governance, risk, compliance, policies and security controls.

Do You Need a Degree to Work in Cybersecurity?

Not always. A degree in computer science, cybersecurity, information technology or a related subject can be useful, particularly for graduate roles, but it is not the only route.

Employers may also consider practical skills, relevant certifications, previous IT experience, apprenticeships and evidence that you can solve real problems. If you do not have a degree, building a strong foundation and gaining relevant experience can make a significant difference.

For people starting from scratch, an IT support role can be a practical first step. Jobdoor’s guide to choosing an entry-level job based on your skills and personality explains how technical support roles can lead towards cybersecurity and other technology careers.

Skills You Need for a Cybersecurity Career

You do not need to master everything before applying for your first role. Focus on building a solid foundation.

1. Networking Basics

Understand concepts such as IP addresses, DNS, TCP/IP, ports, routers, firewalls and how devices communicate across networks.

2. Operating Systems

Become comfortable with Windows and Linux. Learn basic command-line usage, users and permissions, processes, files and system configuration.

3. Security Fundamentals

Understand common threats, authentication, access control, malware, phishing, encryption, vulnerability management and basic security principles.

4. Problem-Solving

Cybersecurity involves investigating unusual behaviour and working out what happened. Analytical thinking is often as important as technical knowledge.

5. Communication

Security professionals regularly explain technical issues to managers, colleagues and customers. Clear communication is a valuable skill.

Cybersecurity Qualifications in the UK

There is no single qualification that every employer requires. Your best choice depends on your current experience and the type of job you want.

Entry-Level Certifications

Beginner-friendly certifications can help demonstrate your understanding of core security concepts. CompTIA Security+ is one example that is commonly associated with entry-level security knowledge.

Networking and Cloud Certifications

Networking knowledge is useful across cybersecurity roles. Certifications and training focused on networking or major cloud platforms can strengthen your technical foundation.

University and Degree Routes

A university course in cybersecurity, computer science or a related subject can provide structured learning and may be useful for graduate recruitment. Compare course content, placement opportunities and overall cost before choosing one.

Apprenticeships

Apprenticeships can combine paid employment with structured training. They can be particularly useful if you want to gain practical experience while developing your qualifications.

How to Get Your First Cybersecurity Job

Your first job may not have the word cybersecurity in its title. That is completely normal.

Start With Related IT Roles

Roles such as IT support technician, technical support assistant, junior systems administrator or network support can help you develop experience with users, devices, accounts, operating systems and troubleshooting.

From there, you can target junior security positions as your technical knowledge grows.

Build a Small Security Portfolio

Practical evidence can make your application more convincing. You could document a home lab, security exercises, a network configuration project, a basic vulnerability assessment or a write-up explaining how you investigated a simulated security incident.

Only test systems that you own or have explicit permission to assess. A portfolio should demonstrate responsible security practice, not unauthorised access.

Tailor Your CV

Do not send exactly the same CV to every employer. Highlight the skills and experience that match the vacancy.

Jobdoor’s guide to writing a CV explains how to structure your experience and present your skills clearly. If you have little or no work experience, a CV focused on education, projects, volunteering and transferable skills can still be effective.

Read the Job Description Carefully

Look at the essential requirements first. Identify the technologies, skills and responsibilities that appear repeatedly and make sure your application addresses the ones you genuinely meet.

Our guide on what to look for in a job description can help you separate essential requirements from desirable ones.

Entry-Level Cybersecurity Jobs in the UK

Depending on your skills and experience, useful job titles to search for include:

Job titles vary between employers, so always read the full vacancy rather than relying only on the title.

How to Build Experience Before Your First Security Job

If you are struggling to get your first cybersecurity interview, look for ways to build relevant evidence.

• Create a small home lab using legal and safe test environments.
• Practise networking and Linux fundamentals.
• Complete structured security training.
• Document personal or academic technology projects.
• Apply for IT support and technology internships.
• Look for apprenticeships and graduate schemes.
• Attend professional or community technology events.

Internships can also provide useful workplace experience. Jobdoor has a guide covering technology internships in the UK.

How Much Can You Earn in Cybersecurity?

Cybersecurity salaries vary significantly depending on location, employer, role, qualifications and experience. Entry-level positions generally pay less than specialist and senior roles, while areas such as cloud security, security engineering, penetration testing and security leadership can offer higher earning potential as experience increases.

Rather than choosing a career based only on salary, compare the responsibilities, skills required, progression opportunities and working environment.

Cybersecurity Career Progression

A possible career path might look like:

IT Support → Junior Security Role → Security Analyst → Senior Security Analyst → Security Engineer, Specialist or Security Manager

This is only one example. Some people move from networking, software development, systems administration, auditing or risk into security.

Common Mistakes to Avoid

Trying to Learn Everything at Once

Cybersecurity is a large field. Start with networking, operating systems and security fundamentals before moving into advanced topics.

Collecting Certifications Without Practical Skills

Certifications can help, but they work best when you can explain how the knowledge applies to real situations.

Applying Only for Jobs Called Cybersecurity

Related IT roles can provide valuable experience and may make the move into security easier later.

Ignoring Communication Skills

Security is not only technical. You may need to write reports, explain risks and work with people across an organisation.

Using a Generic CV

Match your CV to the vacancy and show evidence of the skills the employer actually needs.

Frequently Asked Questions

Can I get into cybersecurity without a degree?

Yes. A degree can be useful, but practical skills, relevant training, certifications and experience can also support a cybersecurity career.
