"3) When it comes to hiring security guards, it doesn't matter whether the guards are employed by an agency or hired directly by the end user; interviewing is essential in order to find the right person for the position. The advantage of using a security guard service is that the company is bonded, background checks have already been made, a certain amount of training has been completed, and the guard can be terminated easily since he works for the agency. The advantage to directly hiring the security guard is greater control over hours, appearance, behavior and in many cases, lower overall costs."
