This shift means cyber security careers are becoming more multidisciplinary. From protecting NHS patient records to defending financial services, securing supply chains & safeguarding national infrastructure, cyber security now touches every sector. Employers increasingly want professionals who understand law, ethics, psychology, linguistics & design alongside traditional technical skills. In this article, we’ll explore why UK cyber security careers are expanding in this way, how these five disciplines shape the profession, and what job-seekers & employers need to know to thrive in this new landscape.
