The Global CISO Gap: 35,000 Security Leaders For 359 Million Businesses

The 2026 CISO Report from Cybercrime Magazine and Sophos examines a cybersecurity industry under mounting pressure.

Cybercrime costs are projected to hit $12.2 trillion annually by 2031, yet only 35,000 CISOs are estimated to be working globally across roughly 359 million businesses. The report describes a widening gap between cyber risk and the availability of experienced security leadership.

Security leadership now extends far outside technical oversight. CISOs are expected to manage ransomware preparedness, AI adoption, regulatory exposure, and supply-chain risk. The role also carries more visibility inside organizations alongside rising turnover, staffing shortages, legal accountability, and burnout.

Why It Matters: The report frames cybersecurity as an operational and leadership challenge with direct impact on governance, workforce stability, regulatory exposure, and financial performance. It also shows how companies are redesigning security programs through managed services and AI-driven operations as traditional hiring approaches fall short.

• CISO Shortage: Only 35,000 CISOs are estimated to be working worldwide in 2026, up slightly from 32,000 in 2023. Large enterprises have normalized full-time CISO leadership, including deputy CISO roles and direct reporting relationships with CEOs. Small and midsized businesses remain far less protected, with many unable to hire dedicated security executives due to cost and talent shortages. This gap has fueled demand for fractional CISOs and virtual CISOs, along with MSPs and MSSPs that provide governance, compliance support, incident response leadership, and risk management services across multiple organizations.

• Burnout and Turnover: Security leadership continues to face high burnout rates and operational strain. Studies cited in the report indicate that 75% of security chiefs are interested in changing jobs, while nearly all CISOs work overtime every week. Average tenure now sits between 18 and 26 months. Legal liability tied to breach disclosure and compliance obligations has added more pressure to the role. Board visibility also continues to rise, with 82% of CISOs now reporting directly to CEOs.

• AI and Human Risk: Artificial intelligence remains a major operational priority across cybersecurity programs. Nearly all surveyed organizations report using AI to strengthen cybersecurity defenses, while AI and machine learning rank among the top expertise areas CISOs want to build or maintain. AI is also improving phishing campaigns and deepfake attacks, along with automated social engineering and attacker efficiency. Human risk management remains a major concern because employee behavior still contributes to most breaches.

• Ransomware and Supply Chains: Ransomware damages are projected to reach $74 billion in 2026 and $275 billion annually by 2031. Sophos research cited in the report places average ransomware demands at $1 million, while average recovery costs stand near $1.5 million. Supply-chain compromises are also becoming more severe, with third-party software breaches doubling in 2025 according to the Verizon Data Breach Report cited in the study. Gartner projections estimate that nearly half of companies will experience at least one software supply-chain incident.

• Regulation and Quantum Risk: Cybersecurity spending continues expanding across enterprises, with more investment coming from departments outside traditional security organizations. Cyberinsurance markets continue to grow as ransomware and breach costs rise. Regulatory scrutiny is also intensifying through GDPR and SEC rules, along with DORA and NIS2 mandates that place heavier reporting obligations on CISOs and executive teams. The report also warns about “Q-Day,” the predicted arrival of cryptographically relevant quantum computing around 2031.
