Corporate espionage is a threat to any business whose livelihood depends on information.
To a medium sized company in the service sector, the information could take the form of detailed client lists or supplier agreements. Regardless, should any of this information find its way to a competitor this would surely have a devastating effect on the business. The basic first line of defense against any form of corporate espionage is a two-pronged approach. Controlled access and knowing your employees and customers. Controlled access means using good quality deadbolt locks and steel clad doors at your place of business, adequate security lighting at night, and installing a monitored alarm system on the premises.
