The presence of a security guard at a business provides peace of mind and a sense of security to the business owner, employees, and customers. Employees, especially those that work in high-risk areas, are more productive and easier to retain when they don’t have to worry about their personal safety. Visible security also lets customers know that you are concerned about their safety and willing to take steps to insure it. This is particularly important for businesses that deal in very high-end merchandise, like jewelry or are located in high-crime areas.
