The main goals of a security department include:

The primary goal of a security department is to ensure the protection and safety of all stakeholders, which encompasses employees, customers, assets, and the organization's reputation. This goal is fundamental because the security department is responsible for implementing measures that protect people and property from various threats, including theft, vandalism, and potential hazards. A secure environment not only fosters a sense of safety but also contributes to the overall functioning and success of the organization.

Additionally, when stakeholders feel safe, their trust in the organization increases, enhancing employee morale and customer loyalty. This protective mandate involves risk assessment, security planning, and the development of policies and procedures that safeguard against potential vulnerabilities. The other choices do not align with the core functions and objectives of a security department. For example, while sales and marketing, change management, and public relations are important areas within a business, they are not the primary focus of a security department's responsibilities.
