Not every incident of unauthorized access is a criminal break-in – some of the most common types spring from common courtesy, like holding the door for a colleague.

 Tailgating is one of the most common and innocent security breaches – an employee opening a door and holding it open for others, visitors without badges, or the passive acceptance of a uniformed worker. The problem with these lax situations and common courtesy is that they open your building to undocumented and unauthorized entry by individuals who could intend harm to your property and employees.
