Number of Cybersecurity Pros Surges 194% in Four Years

Why It Matters

The rapid expansion underscores escalating cyber risk and the urgent need for skilled talent, while the gender imbalance threatens long‑term innovation and resilience in the sector.

Key Takeaways

• Cyber workforce grew 194% from 2021 to 2025
• 83,700 pros, one per 68 businesses
• Cyber is fifth fastest‑growing occupation nationwide
• Women represent only 21% of cyber workforce
• Talent shortage persists despite rapid growth

Pulse Analysis

The unprecedented growth of the UK cyber talent pool reflects mounting digital threats and regulatory pressure on organisations to bolster defences. By 2025, the sector boasts 83,700 specialists, a figure that dwarfs growth in other IT roles, which averaged under 10% over the same period. This surge positions cybersecurity as the nation’s fifth‑fastest‑growing occupation, signalling that businesses are finally prioritising security as a core capability rather than an afterthought.

However, the headline numbers mask a deeper talent crunch. With one cyber professional for every 68 enterprises, many firms—especially outside London and the South East—struggle to secure adequate coverage. The shortage drives higher salaries, increased reliance on managed detection and response providers, and heightened burnout risk among existing staff. Industry leaders stress that expanding training pipelines, investing in employee wellbeing, and decentralising talent hubs are essential to sustain growth without compromising service quality.

Gender diversity remains a critical blind spot. Women now comprise just 21% of the cyber workforce, a decline from 24% four years earlier despite a 163% increase in absolute numbers. Initiatives such as NCSC’s CyberFirst Girls competition and women‑focused networking groups aim to reverse this trend, but systemic barriers persist. Closing the gender gap will not only broaden the talent pool but also enrich problem‑solving perspectives, bolstering the sector’s capacity to counter sophisticated adversaries in the years ahead.
