Growth in Global Cybersecurity Workforce Continues, But Record-Breaking Gap of 4 Million Cybersecurity Professionals Looms

In a world increasingly reliant on technology, the importance of a robust cybersecurity workforce cannot be overstated. The International Information System Security Certification Consortium, or ISC2, has recently published its 2023 Cybersecurity Workforce Study, shedding light on both the growth and challenges within this critical field. Despite a record-breaking increase in cybersecurity professionals, a staggering gap of 4 million experts still threatens the security of digital assets worldwide.

The Cybersecurity Workforce’s Growth

The ISC2’s report indicates that the global cybersecurity workforce has reached 5.5 million individuals, marking an impressive 8.7% increase from the previous year. This growth equates to 440,000 new jobs, representing the highest workforce ever recorded in the field. The significant expansion of the workforce is undoubtedly a positive development, but it’s overshadowed by the alarming reality: the demand for cybersecurity professionals far exceeds the supply.

The Looming Cybersecurity Workforce Gap

The standout finding from the 2023 ISC2 Cybersecurity Workforce Study is the existence of a gaping workforce gap. This gap has reached a record high of 4 million cybersecurity professionals required to adequately protect digital assets. In other words, we need to double the current workforce to ensure the security of organizations and their critical information in the face of an ever-evolving threat landscape.

Challenges Facing the Cybersecurity Workforce

The report identifies several challenges facing cybersecurity professionals today:

  1. Workforce and Skills Gaps: A staggering 92% of cybersecurity professionals report skills gaps at their organizations. The top three areas with skills gaps are cloud computing security (35%), artificial intelligence/machine learning (32%), and zero trust implementation (29%). Importantly, organizations that have experienced cybersecurity layoffs are more likely to face significant skills gaps.
  2. Economic Uncertainty: Nearly half (47%) of respondents have experienced cutbacks, including budget cuts, layoffs, and freezes on hiring and promotions. These cutbacks have negatively impacted productivity, team morale, and increased workloads. They have also hindered organizations’ ability to respond effectively to threats.
  3. Emerging Technologies: A significant portion (47%) of respondents admitted to having minimal knowledge of artificial intelligence (AI). Yet, AI is expected to be a top challenge for cybersecurity professionals over the next two years. Additionally, 47% believe cloud computing security is the most sought-after skill for career advancement.

Fostering Diversity and Inclusion in Cybersecurity

To address these challenges, organizations are actively adopting strategies to strengthen their cybersecurity teams. These strategies include staff training, flexible work conditions, diversity, equity, and inclusion (DEI) programs, support for certifications, and expanding teams by recruiting new staff. DEI initiatives are crucial for promoting a more diverse workforce, enhancing workforce effectiveness, and improving preparedness in dealing with cyber threats.

Hiring for Non-Technical Skills

In addition to technical proficiency, cybersecurity professionals emphasize the importance of non-technical attributes. Problem-solving skills, curiosity, eagerness to learn, and effective communication are essential qualities that complement technical expertise in this field.


The 2023 ISC2 Cybersecurity Workforce Study paints a complex picture of a growing cybersecurity workforce amidst numerous challenges. While the increase in professionals is commendable, the massive workforce gap remains a pressing concern. To address this gap and fortify our digital defenses, organizations must invest in their cybersecurity teams, embrace diversity and inclusion, and recognize the value of non-technical skills in addition to technical expertise. Only by taking these measures can we ensure the resilience and security of our digital world in an era of increasing cyber threats.
