Cybersecurity Talent Gap Widens: ISC2 Report Shows Global Shortage of 4.8 Million Professionals

ISC2 releases 2027 Cybersecurity Workforce Study showing global cybersecurity professional shortage reaches 4.8 million, expanding 22% from the previous year.

ISC2 released its 2027 Cybersecurity Workforce Study on January 17. The report shows the global cybersecurity professional shortage reached 4.8 million, expanding 22% from 3.92 million in 2026.

The report notes that AI-driven cyberattack tools have lowered attack barriers, causing cyber incidents to increase 67% year-over-year, while security talent cultivation speed cannot keep pace with demand growth. The US, China, UK, and Japan face the largest talent gaps.

ISC2 CEO Clar Rosso stated: "AI is simultaneously transforming both offense and defense. Attackers use AI to automate attacks while defenders need AI-savvy security talent to respond. This dual demand is accelerating talent gap expansion."

The report recommends that governments and enterprises increase investment in cybersecurity education, calling for an international unified cybersecurity talent certification system. ISC2 also notes that while AI security tools can partially mitigate talent shortages, they cannot fully replace human security analysts' judgment capabilities.
