What role do security guards play in physical security?

Security guards play a crucial role in physical security by serving as both a deterrent to potential criminal activity and as responders to security incidents. Their presence can discourage unauthorized access and improper behavior, providing a visual reminder that surveillance is in place, which can help to prevent incidents before they occur. In the event of a security breach or emergency, security guards are trained to respond quickly and effectively, ensuring the safety of individuals in their vicinity and mitigating potential threats.

In contrast, the other options describe roles that either do not align with the primary responsibilities of security guards or focus on unrelated functions. For example, simply monitoring access points—while part of a security guard’s duties—is not the full scope of their role, which includes active engagement and incident management. Managing financial transactions or performing technical maintenance is outside the typical responsibilities of security guards, emphasizing the specialized nature of their function within the broader context of physical security.
