This may sound like a no-brainer, but there are a few characteristics that you should consider when choosing a security guard!
Personality
First, do they fit within the company culture? Does their personality match or compliment the other employees? If tnot, major issues can arise. This comes down to basic human instinct! If your security staff does not get along with their coworkers, they likely do not enjoy going to work or respect their company. As a result, when there is a security threat, they may not care or do their best to resolve the problem.
Are they calm? Or more importantly, are they calm under pressure? If the security guard is not calm by nature, they likely will not be calm during a heightened situation. If they cannot stay calm, the person that is causing the problem will not calm down, either.
Are they well spoken? Communication is key! If they cannot effectively and efficiently communicate, issues can quickly escalate. Additionally (and unfortunately), they also may not be taken seriously.
Dependability
Bad situations can happen in an instant and when a security guard is late (or worse — does not show up for work), your company is exposed to risk. Therefore it is critical that you employ a reliable security team.
