Abstract
The manuscript argues that the widely cited cybersecurity workforce shortage is partly a measurement problem rather than a single, uniform labour-market condition. Common estimates of unmet cybersecurity demand often combine fundamentally different constructs, including perceived organisational need, job-posting activity, modelled workforce requirements, and empirically observed shortages. When these measures are treated as equivalent, headline figures can create the impression of a persistent and universal shortage even when labour-market evidence suggests a more differentiated picture. This study critically examines cybersecurity workforce evidence across the United States, United Kingdom, and European Union, with particular attention to the methodological differences underlying commonly cited shortage estimates. Using publicly available secondary data from government reports, industry workforce studies, labour-market datasets, and academic literature, the study compares workforce-need estimates with validated or modelled indicators of labour demand. The findings indicate that cybersecurity labour-market pressure is unevenly distributed across jurisdictions, experience levels, and occupational domains. Evidence from the United Kingdom, for example, suggests that the aggregate workforce has expanded while the estimated annual skills shortfall has declined substantially. At the same time, specialised roles requiring substantial prior experience may remain difficult to fill, while entry-level candidates can encounter comparatively greater competition. The study therefore reframes the cybersecurity workforce shortage as a segmented labour-market phenomenon rather than a universal deficit of cybersecurity professionals. The paper concludes that workforce policy, cybersecurity education, professional certification, recruitment strategies, and career guidance should distinguish between entry-level accessibility, experienced-specialist scarcity, organisational demand, and structurally validated labour shortages. Greater methodological consistency and longitudinal labour-market measurement are necessary for producing more reliable estimates of the cybersecurity skills gap.
