Sometimes—but there is no evidence-backed rule that every organization should split the CISO role. A second leader can help when enterprise risk and board-level strategy compete with the work of implementing controls and running day-to-day security. The split works only if decision rights, risk ownership, oversight, and incident escalation are explicit; otherwise, it can create handoffs without resolving accountability.
What does splitting the CISO role mean?
It means assigning parts of the security leadership remit to distinct accountable leaders rather than expecting one CISO to personally lead enterprise strategy, governance, control delivery, operations, and incident response. It does not necessarily mean reducing the CISO’s visibility into operations or removing the CISO from incident leadership.
One model described by KPMG International’s 2025 cybersecurity guidance gives the CISO responsibility for enterprise risk management and broader cybersecurity strategy, while a Technology Information Security Officer (TISO), embedded in technology, oversees control implementation and day-to-day operations. Larger, diverse organizations may also have business-line CISOs alongside an enterprise leader.
These are organizational options, not proven prescriptions. The available sources do not establish that a split reduces incidents, improves resilience, lowers liability, or produces a return on investment.

What evidence says about CISO scope and role clarity
Documented examples show that CISO responsibilities can span strategic and operational work, but they do not establish how every organization should structure the role.
- State government scope: Deloitte and NASCIO reported that the share of state CISOs offering strategy, governance, and risk management services rose from 81% in 2022 to 100% in 2026. In the 2026 state survey, about 77% of respondents said their scope covered executive-branch agencies, departments, and offices. These are state-government findings, not estimates for private-sector CISOs. See the 2026 NASCIO-Deloitte Cybersecurity Study.
- Earlier state-government findings: In the 2024 Deloitte-NASCIO study, 98% of state CISO offices covered security management and operations, 98% covered strategy, governance, and risk management, and 96% covered incident response. The study also reported that state CISO privacy responsibility rose from 60% in 2022 to 86% in 2024. These figures describe state CISO offices and the study periods, not all organizations. See the 2024 Deloitte-NASCIO Cybersecurity Study.
- Federal role definition: The U.S. Government Accountability Office reported in 2016 that 13 of the 24 federal agencies it reviewed had not fully defined the CISO’s role in accordance with applicable law and guidance. That finding concerns the agencies reviewed, not organizations generally. The GAO report includes recommendation status updates through 2025.
- Control implementation and monitoring: An ISACA Journal article in 2024 described a qualitative study of five multibillion-dollar organizations using 24 semistructured interviews. All except the bank had not segregated implementation of controls from monitoring; responsibilities were often integrated or distributed across multiple units. The small sample illustrates possible arrangements, but cannot establish which structure performs best elsewhere. See “The Three Lines Model in Cybersecurity Governance and Risk Management.”
Three ways to organize the work
| Structure | How responsibilities are allocated | Potential value | Main design risk |
|---|---|---|---|
| One integrated CISO | The CISO owns strategy, risk, governance, operations, and incident leadership, delegating execution to teams. | Unified accountability and fewer executive handoffs; may fit where a separate senior role is not warranted. | Scope overload, or insufficient independent oversight if the CISO lacks authority or capacity. |
| CISO plus TISO or security operations leader | The CISO leads enterprise risk, governance, and strategy; a technology-embedded TISO leads control implementation and daily operations. | Dedicated operational leadership while preserving enterprise-level risk leadership. | Split decisions, weak handoffs, or unclear escalation and oversight. |
| Enterprise CISO plus business-line CISOs | An enterprise leader sets overall direction while business-line CISOs address distinct business contexts. | May suit a large, diverse organization with materially different risk environments. | Duplicated work or inconsistent standards without clear enterprise authority and coordination. |
The options above are described in KPMG guidance; the sources reviewed do not provide comparative performance data or a universal threshold for choosing among them.

When is a split worth considering?
Consider a separate operational security leader when the organization has enough scale and distinct work to support both roles, and the current arrangement consistently forces tradeoffs between strategic governance and delivery. A split may also make sense when a technology organization needs a dedicated leader for control implementation and daily operations.

For each activity, establish who decides, who implements, who monitors, who accepts residual risk, and who can escalate. Include:
- Enterprise risk appetite, risk reporting, and board or executive communication.
- Security policy, governance, and control design.
- Control implementation, security operations, and incident response.
- Assurance and monitoring, including the path for independent review where needed.
- Privacy and other adjacent responsibilities that currently sit with the CISO or the CISO’s office.
Then test the proposed arrangement against six practical questions:
- Risk accountability: Is it clear who owns enterprise cyber risk and who is authorized to accept residual risk?
- Delivery and oversight: Are control implementation and monitoring appropriately separated or deliberately integrated, with any necessary independent assurance preserved?
- Authority: Can each leader make the decisions their remit requires, and can either escalate a material concern without obstruction?
- Capacity: Is operational workload actually displacing strategy, governance, or executive risk work, or would better delegation within one function address it?
- Coordination cost: Will the extra handoffs improve focus enough to justify the time and ambiguity they can introduce?
- Organizational fit: Do the organization’s scale, business diversity, and available senior talent support distinct accountable roles?
How to prevent gaps after a split
A split is defensible only when the operating model is explicit. A job title alone does not create accountability or independent oversight.
- Write down the boundary: Document which leader sets policy and risk direction, which leader implements controls, and where authority is shared.
- Connect risk to operations: Give the CISO regular visibility into control performance, operational risks, and incident conditions. The operational leader needs a clear route to raise issues that could change enterprise risk.
- Set incident-time authority in advance: Specify who can direct operational action, who coordinates enterprise decisions, and how disagreements are escalated when time is short. KPMG’s guidance emphasizes clear authority, autonomy, and accountability, especially during incidents.
- Assign monitoring deliberately: If implementation and monitoring are separated, identify the independent assurance path and its access to decision-makers. If they remain integrated, define how conflicts of interest or weak control performance will be surfaced.
- Keep standards coherent: For business-line CISOs, establish enterprise-wide minimums and a process for handling local exceptions, shared services, and duplicated responsibilities.
Should your organization split the role?
Split it when distinct strategic and operational workloads, organizational scale, and governance needs justify separate leaders—and when the organization can define accountability, oversight, coordination, and escalation before the roles are created. Keep responsibilities integrated when a separate executive layer would add handoffs without addressing a real capacity or governance problem.

The evidence supports treating the choice as a governance design decision, not as a universal best practice. State surveys, a federal agency review, professional guidance, and a small qualitative study describe scope and structures; none provides a controlled comparison proving that split or unified CISO arrangements produce better outcomes.
