What is one main responsibility of security guards while on duty?

One main responsibility of security guards while on duty is to monitor access points and control entry. This duty is crucial for maintaining a secure environment, as it prevents unauthorized individuals from accessing restricted areas. Security guards are trained to observe and manage who enters and exits a facility, ensuring that only authorized personnel are granted access. By effectively monitoring these entry points, they help safeguard the premises from potential threats, such as theft, vandalism, or other security breaches.

In addition to this primary responsibility, guards may engage in other activities that contribute to overall security. However, the key focus remains on access control, which is fundamental to their role in protecting the assets and safety of the organization they serve.
