Global digital transformation, accelerated by the COVID-19 pandemic and the rise of remote work, has expanded the scope of security challenges.
As businesses increasingly adopt cloud-based technologies, artificial intelligence tools like ChatGPT, and interconnected systems, security risks have multiplied. These developments, along with the rising sophistication of cyberattacks, have pushed organisations to adopt a more comprehensive approach to security.
Today, Chief Security Officers (CSOs) and Chief Information Security Officers (CISOs) are often seen as interchangeable roles. The distinction, however, marked by “information” in the title is significant. While both positions are responsible for safeguarding an organisation’s assets and ensuring security, their scope and focus can differ considerably.
Traditionally, ais a C-Suite executive focusing on safeguarding information systems and ensuring data confidentiality, integrity, and availability. A CSO encompasses a broader remit and addresses both physical and digital security threats.
With so much overlap between the roles, many organisations wonder if they need both a CSO and CISO, or if one leader can handle physical and digital security responsibilities.
For larger companies with significant physical and digital assets, having both roles can be essential, with the CSO typically focusing on physical security and overall risk management, while the CISO is dedicated to cybersecurity and protecting digital infrastructure.
In smaller organisations, these roles are often combined and sometimes even absorbed by the Chief Information Officer (CIO).
Jason Clark, Chief Strategy Officer at Cyera and former CISO, explains: "Security leadership is about adapting to the business's needs—whether that’s managing risks across the board or focusing on specific areas like data or operational resilience."
This flexibility has driven the evolution of these roles, with modern threats often spanning both physical and digital domains.
Ultimately, whether separate or combined, the CISO and CSO must work closely together to ensure security strategies align with business goals and stay ahead of emerging risks.
The change from CISO to CSO marks a significant shift in responsibilities, requiring technical expertise and strategic foresight. While this transition is challenging, it also offers opportunities for growth and influence.
Developing the skills required to transition from CISO to CSO is a priority for organisations seeking future-ready leadership. For those aspiring to step into this expanded role, programs like the EC-Council's Chief Information Security Officer (C|CISO) certification offer invaluable training.
The C|CISO certification equips cybersecurity professionals with expertise in governance, strategic planning, and advanced security controls, which are essential tools for navigating the challenges of modern security leadership. By investing in such programs, professionals can position themselves as leaders capable of driving innovation, managing risk, and aligning security with business goals.
