Which type of security involves hiring third-party security firms?

The type of security that involves hiring third-party security firms is known as contracted security. This approach allows organizations to outsource their security needs to external firms that specialize in providing security services. By doing so, organizations can leverage the expertise, resources, and specialized skills of these firms, which may be more cost-effective and efficient than maintaining an in-house security team.

Contracted security is often used by businesses that require flexible security solutions for specific events, locations, or periods, enabling them to focus more on their core operations while ensuring their security needs are met by professionals who are trained to manage various security challenges.

In contrast, proprietary security typically refers to security personnel who are employed directly by an organization rather than contracted from an external source. Public security often involves government-operated agencies responsible for general public safety, and hybrid security combines both in-house and outsourced security services. Each of these alternatives serves different operational needs but does not involve the direct engagement of third-party security firms for the primary security functions, as contracted security does.
