A Chief Information Security Officer (CISO) is responsible for governing information security, managing security risk, ensuring regulatory compliance, and reporting security posture to executive management and boards. The role focuses on accountability and decision-making, not day-to-day technical operations.
A Chief Information Security Officer (CISO) is accountable for the organization’s information security posture at an executive level. The role centers on governance, risk oversight, compliance assurance, and strategic decision-making rather than managing technical security tools or infrastructure.
In the current regulatory environment, CISOs are expected to demonstrate clear ownership of security risks, especially under regulations such as GDPR, NIS2, and DORA. Security incidents are no longer treated as isolated IT failures but as governance failures with potential legal, financial, and reputational consequences.
Practically, a CISO defines and oversees the information security program, including policies, risk management processes, incident management structures, and performance metrics. They ensure that security controls are aligned with business priorities and that residual risks are explicitly accepted by the appropriate level of management.
A CISO also acts as the primary interface between technical teams and executive leadership. This includes translating technical vulnerabilities into business risk, advising executives on investment decisions, and preparing security reporting suitable for boards, regulators, and auditors.
In many organizations, the CISO does not directly manage all security teams. Instead, the role focuses on influence, governance authority, and cross-functional coordination across IT, legal, compliance, and business units.
We see many organizations struggle because they misunderstand the CISO role. They expect deep technical expertise and overlook governance skills. Effective CISOs know how to structure reporting, define risk acceptance thresholds, and push decisions to the right level of management.
One practical tip: strong CISOs invest early in metrics. If you cannot explain security posture in three or four indicators that executives understand, you will struggle to influence decisions. This is where many technically strong professionals fall short when stepping into executive roles.
““If you’re spending most of your time configuring tools, you’re not acting as a CISO—you’re acting as a senior engineer with a different job title.””
