A proactive security approach prevents major incidents before they happen. Preventative measures taken by a company anticipate potential situations and save the organization from experiencing devastating events that can lead to crippling losses from theft, fire or natural disaster. In addition, the physical manifestations of a proactive security system such as signs, cameras and passwords act as visible deterrents to thieves, vandals and hackers. On the other side reactive security approach calls for companies to respond to past and present threats, rather than anticipate future dangers. When the company falls victim to a threat, the owners determine the level of the threat, assess the amount of the damage and install measures to prevent such an event from reoccurring. Since no business can anticipate every possible threat but businesses can choose to take a proactive approach, in which they act to prevent any dangers before they occur, or a reactive approach, in which they respond to a security breach after it has happened. There’s a difference between crime prevention and crime reaction, though many take the reactive approach and don’t consider purchasing an alarm system, for example, until after they’ve been burglarized or property has been stolen.
