Possible careers in cyber security

Cyber security offers far more than just one type of job. It’s a diverse and dynamic field that includes everything from hands-on technical work to strategic management roles. Whether you enjoy solving puzzles, analysing data, or leading teams, there’s a cyber career that fits your skills and goals.

  • Security analyst

    Information Security Analysts are among the most in-demand professionals in the IT sector. They’re the ones keeping an eye on IT networks, spotting weaknesses and vulnerabilities, and responding when cyber security threats appear. It’s a hands-on role at the frontline of defence – preventing data breaches and helping stop cyber attacks before they spread.

    Employers recruiting security analysts look for people who understand operating systems, firewalls, and network monitoring tools, but just as important is the ability to think fast and stay calm under pressure.

  • Network security engineer

    Network Security Engineers design, build, and maintain the secure systems that connect people and data. They develop firewalls, VPNs (virtual private networks), and intrusion detection systems to make sure information travels safely across an organisation’s network.

    Because so much data now moves between offices, data centres, and cloud platforms, this role is essential for almost every company, especially those handling sensitive information.

  • Penetration tester

    Penetration Testers, also known as ethical hackers or white-hat hackers, simulate cyber attacks to find vulnerabilities in computer systems, software, and processes. Their goal is to identify weaknesses before malicious actors exploit them.

    As the job title suggests, this career path requires strong hacking skills. In-depth knowledge of operating systems and software is a given and can be supplemented by specific certifications, such as the Certified Ethical Hacker (CEH).

  • Security manager

    As a Security Manager, you are responsible for an organisation’s overall security strategy. That includes technical skills such as risk management, as well as more legal topics, like compliance with ethical standards. Since the jobs hold responsibility at a larger scale, coordination across different departments is mandatory.

    With an interdisciplinary background, Security Managers ensure that cyber security processes and systems are aligned with business goals and that staff follow secure practices. In terms of soft skills, strong leadership and communication skills are definitely essential for this role.

  • Incident response specialist

    Incident Response Specialists are like digital firefighters. When an attack happens, they’re the first to respond - identifying the threat, containing it, and helping systems recover safely.

    Their expertise in intrusion detection and forensics makes them vital for companies and other organisations facing advanced cyber attacks.

  • Cloud security specialist

    As organisations move more data and applications into the cloud, Cloud Security Specialists are in high demand. They design and implement measures to protect cloud-based infrastructure and multi-cloud environments.

    Since threats to these systems are diverse and numerous, the day-to-day work of these specialists is diverse and varies. From risk and access management to making sure even multi-cloud environments are secure - a cloud security specialist does it all.

The best career option in cyber security for you

Choosing the right cyber security role starts with understanding your own strengths and interests. Are you analytical, creative, detail-oriented, or a natural communicator? Each trait can align with different cyber security positions.

The field itself covers everything from protecting computer systems and networks to developing long-term data protection strategies. Knowing what motivates you will help you find the best fit.

Enjoy problem-solving?

For those who enjoy problem-solving and analysis, roles such as Information Security Analyst or Security Operations Centre (SOC) Analyst may be a strong fit. These professionals are responsible for monitoring IT networks, identifying vulnerabilities, and responding to threats.

In the US alone, employment of information security analysts is projected to grow by 32 per cent between 2022 and 2032 (US Bureau of Labor Statistics), much faster than the average for all occupations.

Example: Think of these analysts as the digital equivalent of emergency responders, acting quickly when systems are under attack.

Good with communication and management?

Cyber security isn’t all about code. If you’re good at organising people, communicating clearly, and thinking strategically, roles in security management or risk analysis may suit you best.

These professionals develop company-wide security policies, ensure compliance with data protection regulations, and translate technical risks into language that non-technical teams can act on.

Example: A Security Manager might brief a company’s leadership on how to prevent ransomware attacks or manage an employee training programme to reduce human error.

There is no "one-size-fits-all" solution

Because cyber security spans such a wide range of skills and responsibilities, there’s no universal career path. Some people enter through IT support or computer science, while others transition from law, risk management, or even psychology.

The best choice is the one that aligns with your personal strengths and professional interests. Our Cyber Security Guide provides further detail on common career paths, job titles, and the responsibilities associated with each role.

A word on career flexibility

One of the biggest advantages of working in cyber security is flexibility. Professionals often move between roles as they gain experience or discover new interests. You might start as a junior analyst, develop skills in ethical hacking or cloud security, and later advance to leadership positions such as Chief Information Security Officer (CISO).

Example: Someone who begins by monitoring firewalls and responding to incidents might later design company-wide security strategies or lead a global cyber defence team.

Cyber security is also a field that evolves constantly. New technologies, like artificial intelligence or blockchain, bring new challenge and new specialisations. That means there’s always room to learn, adapt, and grow.

Students and career changers interested in these opportunities may benefit from advanced training. Our MSc Computer Science with Cyber Security provides a structured pathway to gain the technical skills and qualifications required for these roles.

Possible Careers in Cyber Security

Cyber security offers distinct tracks that map to specific strengths: analysts and SOC roles for problem-solvers, network and cloud engineering for builders, penetration testing for adversarial thinkers, incident response and forensics for calm crisis-handlers, and security management/risk for strong communicators and strategists.

Careers are fluid and stackable: you can move between specialities and progress to leadership, as your technical depth and strategic impact grow.
