To save money, many companies opt to use a shared server to host their site's files. This means many different sites are running on the same machine, sharing the same programs and scripts to run applications that are common to all of the sites - things like email services or control panels, for example. This means that it's not just one or one company's staff that has access to one server. Hundreds (If Not Thousands) of other people in other companies do as well. If one provider or a fellow customer is lax in its security and a site on one shared server gets compromised, one site and its data are at risk as well.
