UK employers' tech hiring plans run into a cyber workforce that grew 2% in a year

Robert Half's survey measures intent. Government data on the cyber workforce is the nearest check on it. Against 2% growth in that workforce ^[10], core cyber security job postings rose 7% ^[11], and postings for roles that need cyber skills without carrying the label rose 10% ^[12]. Postings count advertisements and the workforce figure counts people. The gaps of 5 and 8 percentage points ^[1][2] show a direction and cannot be read as a count of missing staff. The skills-gap figure moved the same way, up 8 points in a year ^[3].

The skills list is flatter than the top line suggests. Cyber security leads at 54%, followed by agentic AI at 50%, generative AI at 48% and cloud at 44% ^[2]. That is a spread of 10 points from first to last ^[4], so employers want all four. ITPro's account of the research does not give a sample size, or say whether those shares are of all employers or only of the 47% planning to grow ^[1].

The board-deck version is a headcount line: add security and agentic AI people before year-end. Robert Half's own description of demand is harder to fill. "Businesses continue to invest heavily in cyber security, cloud infrastructure, and artificial intelligence, but they're not simply looking for more people. They're looking for professionals with the right blend of technical expertise, commercial understanding and the ability to work effectively alongside AI," said Matt Weston, senior managing director for the UK and Ireland at Robert Half ^[4]. Asking for that blend in one candidate narrows a pool the government says grew 2% ^[10].

People already on the payroll carry the rest of the demand. In the same research, 45% of UK technology professionals said they are now expected to develop new AI-related skills ^[5]. Over half, 53%, said AI has cut the time they spend on routine tasks, and 37% said their roles have become more strategic ^[7]. "AI is automating some tasks, but it isn't replacing the need for skilled technology talent," Weston said ^[8]. Robert Half's researchers said the findings point to demand for people who apply human judgment to ensure accuracy, quality, security and compliance ^[16].

A skeptic would say a hiring plan is cheap to state in a survey and easy to drop by December. The objection holds for the 47% ^[1]. It is weaker against the postings figures ^[11][12]. Those count roles employers have already advertised. Robert Half expects competition for specialist talent in cyber security, AI and cloud to stay strong ^[9].

This quarter's trade-off is between buying scarce specialists and training the staff who already check AI output. Contract and project hiring ^[3] adds capacity for some employers. The government's free courses ^[14] and the NCSC's training for novice and experienced security professionals ^[15] lower the cash cost of training. I'd expect the choice made before year-end to show up next quarter. A team that hires for agentic AI and trains no reviewers will produce more machine output with the same number of people able to check it.
