The Skills Gap in Cyber Security Jobs: What Universities Aren’t Teaching

Cyber security has become one of the most critical disciplines in the modern economy. From protecting financial systems and healthcare data to securing national infrastructure, cloud platforms and supply chains, cyber security professionals now sit at the frontline of digital trust. Demand for cyber security talent in the UK has surged. Job vacancies remain high, salaries continue to rise, and organisations across every sector report difficulty hiring skilled professionals. Yet despite this demand, many graduates struggle to break into cyber security roles and employers consistently report that candidates are not job-ready. The problem is not intelligence, ambition or academic effort. It is a persistent and widening skills gap between university education and real-world cyber security work. This article explores that gap in depth: what universities teach well, what they routinely miss, why the gap exists, what employers actually want, and how jobseekers can bridge the divide to build sustainable careers in cyber security.

How to Write a Cyber Security Job Ad That Attracts the Right People

Cyber security is now a board-level priority for organisations across the UK. From financial services and healthcare to critical infrastructure, SaaS platforms and the public sector, demand for skilled cyber security professionals continues to grow. Yet despite this demand, many employers struggle to attract the right candidates. Cyber security job adverts often generate large volumes of applications, but few are a genuine match. Meanwhile, experienced security engineers, analysts and architects quietly ignore adverts that feel vague, unrealistic or disconnected from real security work. In most cases, the problem is not a lack of talent — it is the quality of the job advert. Cyber security professionals are trained to assess risk, spot weaknesses and question assumptions. A poorly written job ad signals organisational immaturity and weak security culture. A well-written one signals seriousness, competence and trust. This guide explains how to write a cyber security job ad that attracts the right people, improves applicant quality and positions your organisation as a credible security employer.
