What term describes security services provided by an organization's own staff?

The term that describes security services provided by an organization's own staff is proprietary security. This type of security involves personnel who are directly employed by the organization to safeguard its assets and ensure a safe environment. Organizations opt for proprietary security to have greater control over their security practices, instill organizational culture within their security team, and ensure that their specific needs and priorities are closely aligned with their security operations.

Proprietary security personnel often have a more profound understanding of the organization's culture and objectives, which enables them to respond to incidents and manage security in a way that reflects the organization’s values and policies. This approach fosters a sense of loyalty and commitment among staff, who are invested in protecting their own workplace.

In contrast, public security typically refers to services provided by government agencies or public sector entities aimed at ensuring public safety, while contracted security involves hiring external firms to perform security functions. Hybrid security combines elements of both proprietary and contracted approaches, utilizing both in-house staff and external contractors. Each of these alternatives serves different needs, but proprietary security distinctly focuses on an organization's own employees as the primary security personnel.
