What is one benefit of a security guard being visibly present?

A visibly present security guard serves as a powerful deterrent against potential criminal activity. The mere appearance of security personnel can make individuals think twice before attempting to engage in unlawful behavior, such as theft or vandalism. This proactive approach helps to maintain a safe environment, as potential wrongdoers are less likely to act if they perceive that there is a risk of being caught by a security professional on-site.

The presence of security guards not only contributes to immediate safety but also fosters a sense of security among employees and visitors. When individuals feel secure, they are more likely to thrive in their work environment, leading to enhanced productivity and a positive workplace culture.

In contrast, the other choices do not align with the primary function of a security guard's presence. While keeping a workplace quiet may be a desired effect in certain contexts, it is not a primary benefit of security personnel. Similarly, creating a negative atmosphere or intimidating employees contradicts the intended supportive role of security guards, which is to promote safety and security rather than to instill fear.
