What is a CSO in Security?

A Chief Security Officer (CSO) is a senior executive responsible for developing and overseeing an organization’s overall security strategy, including the protection of people, physical assets, information, and business operations. Depending on the organization, the CSO may oversee both physical security and cybersecurity or work alongside a Chief Information Security Officer (CISO) who focuses specifically on information security.

The scope of the CSO role varies by industry, organizational size, and governance structure. In some organizations, the titles CSO and CISO are used interchangeably, while in others they represent distinct executive positions with different responsibilities.

What does a CSO do?

A CSO establishes enterprise-wide security policies and coordinates security initiatives across multiple business functions. The role typically balances strategic planning, operational oversight, and risk management to protect the organization from a wide range of threats.

Common CSO responsibilities include:

Responsibility  Purpose 
Enterprise security strategy  Develop a comprehensive security program aligned with business objectives. 
Risk management  Identify and manage physical and cyber risks. 
Security governance  Establish security policies, standards, and oversight. 
Incident management  Coordinate organizational responses to security incidents and crises. 
Business resilience  Support continuity and resilience planning. 
Executive collaboration  Work with leadership teams on security-related decisions and investments. 

The CSO also collaborates with IT, legal, facilities, compliance, and executive leadership to strengthen organizational security.

CSO vs. CISO

Although the two roles often work together, their primary focus may differ depending on the organization’s structure.

Feature  CSO  CISO 
Primary focus  Enterprise security, including physical and organizational security  Information security and cyber risk 
Scope  Physical security, business resilience, governance, and security strategy  Cybersecurity strategy, information protection, and compliance 
Leadership  Cross-functional security leadership  Information security leadership 
Relationship  May oversee multiple security functions  May report to or collaborate with the CSO, depending on the organization 

Some organizations combine both responsibilities into a single executive role, while others separate them based on business needs.

Why is the CSO role important?

Security risks extend beyond cybersecurity to include physical threats, insider risks, operational disruptions, and regulatory obligations. The CSO provides executive leadership that helps organizations coordinate security efforts across departments and align security initiatives with business priorities.

As organizations adopt hybrid work, cloud services, and distributed operations, the CSO plays a key role in improving organizational resilience and enterprise risk management.
