What is the primary function of a security department within a private business?

The primary function of a security department within a private business is the protection of its own property and grounds. This encompasses a wide range of responsibilities including safeguarding physical assets, ensuring the safety of employees and customers, and preventing theft, vandalism, or any security threats to the organization. The security department focuses on creating a secure environment where the operations of the business can proceed without interruption.

While other functions such as offering security services to the public or providing consultancy may be aspects of larger security firms or services, they do not represent the central purpose of a private business's internal security department. The primary objective remains the protection and preservation of the company's own resources and environment, thereby supporting its overall mission and operational integrity.
